Re: [hugin-ptx] Optimizer GUI x Script

[Carlos Eduardo G. Carvalho (Cartola)]

Hi LF,

the reason for samples it that I would be able to understand better what
your intention is and maybe could be able to suggest alternatives. I'm not
a developer, maybe someone could explain better how hugin deals with
translation optimization, but I were never, really never able to use it
with good results. From what you say I imagine that using the GUI it is
working. I have already tested translation in PTGui and it worked as I
expected: I was able to join a displaced nadir picture in a full sphere
panorama.

Well, a possible workaround to this image set you sent is using different
lenses for different images instead of translation. This will work only if
the translation is like this: getting closer or away from subject. This way
you can avoid translation and optimize only other parameters.
Here are the optimization steps I've already used to stitch full sphere
panoramas. They ran after all the process of finding CPs on image pairs,
vertical lines and so on.

pto_var --opt y,p,r -o final.pto final.pto
autooptimiser -n -o final.pto final.pto

pto_var --opt y,p,r,v -o final.pto final.pto
autooptimiser -n -o final.pto final.pto

pto_var --opt y,p,r,v,b -o final.pto final.pto
autooptimiser -n -o final.pto final.pto

pto_var --opt y,p,r,v,a,b,c,d,e,g,t -o final.pto final.pto
autooptimiser -n -o final.pto final.pto

Re: [hugin-ptx] Batch script cannot reproduce what I do in GUI

[Carlos Eduardo G. Carvalho (Cartola)]

Hi LFOM,

I've already done a script once for video frames, but I have some doubts
about what you are doing.

I didn't really understand how you get your images, you said the second is
a projection of the first and so on, but anyway, I also don't know if this
is relevant. Maybe you can make some samples available somewhere.

Maybe a more important question is: Did the camera move between frames? If
not then you can do a stitch just for the first 4 images and then use the
PTO file as a template for the rest, just doing the final image rendering.

Re: [hugin-ptx] Align image stack where photos have different dimensions

[Carlos Eduardo G. Carvalho (Cartola)]

Hi Judson,

make sure to specify each image a different lens, so Hugin can resize them
independently when doing visual optimization. You can change lens at the
Photo tab (advanced or specialist interface) by clicking with the right
mouse button over an image.

Re: [hugin-ptx] Re: Problems running Hugin on a MacOS Sierra

Yes, I also understood that it occurs at startup. I passed your suggestion
to him, but he didn't find the Preferences and also said he did't use Hugin
before, the 2017 was the first version installed.

He got 2013 version working after downgrading one at a time.

[hugin-ptx] Problems running Hugin on a MacOS Sierra

[Carlos Eduardo G. Carvalho (Cartola)]

Hi everybody,

I'm trying to help a user at panoforum.com.br that posted a problem he had
when running Hugin 2017.0.0 for the first time. I suggested him to try
older versions, which he did, but the problem persists. He posted the last
two error screens at this post here
, including
a XML process context description generated bu Hugin. I mean the two images
at the fifth message posted.

Any hint? For me those messages say nothing and I also don't have a Mac,

probably many people here already know about "VLC goes 360°"

I've waited for a possible linux binary, but it looks like it doesn't come
out, so I've decided to try to compile it and I've finally finished it
today.

Hi Brian, we would need to know what operational system you are in to be
able to help you with it. On the other hand, this is not a doubt related to
Hugin itself, but to the use of the system, so you will find a lot of
information about it if you search on the web. You can use "Your_OS command
line" to search. Let's say you are on a MacOS computer, search for MacOS
command line
.
Just change the search according to your OS (like Windows, Linux, FreeBSD,
...).

Re: [hugin-ptx] Hugin output without blending

[Carlos Eduardo G. Carvalho (Cartola)]

What size do you want to measure? The image final size is specified in the
Stitch tab. At the same tab you can unset any "Panorama output" and set the
first "Remapped Images" to get one file corresponding to each input image.
If you want it to be the same size of the entire blended image, just open
Nona "Options" and unset "save cropped images".

Re: [hugin-ptx] New to hugin - panoramic image seems to not have blended properly

[Carlos Eduardo G. Carvalho (Cartola)]

As Greg I also think I have seen this before. Did you use any mask? Did you
change the blender or any of its parameter?

Maybe you can also try to change the blender, like using multiblend.

Re: [hugin-ptx] Which distros have Hugin preinstalled ?

I also have this point of view, although hugin also doesn't come
pre-installed on Ubuntu or its variants. Some specific sidtros might have
it, like those intented to graphic people, like Ubuntu Studio or ArtistX. I
just think this is not a very good criteria for choosing a distro. I've
already used ArtistX once and I really didn't like its standard iterface.
Surely I can change it, but it would probably be a harder job thatn just
installing Hugin once. My point is: be carefull to don't be stuck with a
distro you don't like just for the convenience of not installing a
software, which is made once.

I use Xubuntu and have easily installed Hugin using a PPA.

Re: [hugin-ptx] Aligning photos of the same scene with a moving body of water

Sure, I find this option even faster, but as he said he "tried to play with
masks but that doesnt work very good"...

Just in case, the option to "remove control points in masks" is at the Edit
menu at the main window (Panorama Stitcher) using Advanced or Expert

Re: [hugin-ptx] Aligning photos of the same scene with a moving body of water

[Carlos Eduardo G. Carvalho (Cartola)]

You can remove the Control Points (CP) found at the water. You can easily
do that visually at the fast preview window using the "Edit CP" button at
the preview tab (second tab). After activating this button you can drag
rectangles over the image to create new CPs or remove them.

Re: [hugin-ptx] Seams in enblend

2016-11-07 6:43 GMT-02:00 Marius Loots :

> So the question is, how do I get enblend to use the same seam for

>

About this specific question, you can run it in a first moment with the
option "--save-masks" and then you can use this mask with the option
"--load-masks". From the execution of "enblend -h":

  --save-masks[=TEMPLATE]
 save generated masks in TEMPLATE; default:
"mask-%n.tif";
 conversion chars: "%i": mask index, "%n": mask
number,
 "%p": full path, "%d": dirname, "%b": basename,
 "%f": filename, "%e": extension; lowercase
characters
 refer to input images uppercase to the output image
  --load-masks[=TEMPLATE]
 use existing masks in TEMPLATE instead of
generating
 them; same template characters as "--save-masks";
 default: "mask-%n.tif"

Re: [hugin-ptx] more photos?

To see the Control Points at their places, go to the Fast Preview Panorama
windows and then to the Pre-Visualization tab (second tab). Click "show
control points" to see them. You can also click the "Edit CP" button to see
and add or remove CPs in rectangular areas.

Note that the names of windows and tabs I've used might be a little
different as my Hugin is in Portuguese and I've just translated them here
myself.

Before doing that I suggest that you first check if you have shot using a
fixed axis considering the NPP (no parallax point). This is very much
important and you can achieve this by using a panoramic tripod head or a
philopod. If you are shooting hand held then you surely have pictures with
parallax.

There is a "defish" effect on Kdenlive, but I really don't know if it can
do what you need. You can test Kdenlive runnint linux on a pendrive if you
can't install it on your Mac.

Re: [hugin-ptx] Re: Can Hugin change the projection of a video?

[Carlos Eduardo G. Carvalho (Cartola)]

There are many documentation on the Internet on how to make a bash script. Here
is one example .

I guess here you will need basically a loop:

---
#!/bin/bash

for number in $(seq -w 1 18000); do
  /Applications/hugin.2014.0.0/Hugin.app/Contents/MacOS/nona -o output
test.$number.pto test.$number.png
done
---

And if you install ffmpeg you can automate all the job

---
#!/bin/bash

# split the video in frames using 5 digits
ffmpeg -i yourVideo.mp4 -qscale:v 2 frame-%05d.jpg

# count the frames
total=$(ls frame-*.jpg | wc -l)

# loop on the frames
for number in $(seq -w 1 $total); do
  /Applications/hugin.2014.0.0/Hugin.app/Contents/MacOS/nona -o output
test.$number.pto frame-$number.jpg
done

ffmpeg -i output%05d.jpg final_output.mp4

Very nice to find someone from that french forum here! I've created a
Portuguese forum inspired on it in 2011 :) http://www.panoforum.com.br/

It is quite impressive the number of members and quantity of messages that
you have there! I'll try to get involved with it, as it will also help me
studying French ;)

Is there an English open forum dedicated to panoramic photography? I think
that the IVRPA has a closed one (the open is quite poor) and kolor.com also
has its own, which is obviously more focused on their tools.

Re: [hugin-ptx] Samsung gear 360

[Carlos Eduardo G. Carvalho (Cartola)]

2016-07-01 2:44 GMT-03:00 Edmund Ong :

> BTW how do you share your 360 pictures?


There are many ways to share. The last one available is to directly upload
it to facebook, which is very popular and accessible, but doesn't give the
best experience IMHO. To do that you also need to have the right EXIF
parameters, so that facebook recognizes it as a 360 image. Probably it will
recognize the EXIF from Gear 360, but if it doesn't you can set them
manually or just copy exif from a Ricoh Theta image, which is what I've
been doing with "exiftool".

I share my 360 first in my blog, where I've already used Salado Player,
#VR5 and nowadays (and since a long time already) I've been using krpano,
which I still find the best plugin. It is also one of the only ways I've
found to make it available for VR online. IMHO one of the best free plugin
nowadays is Marzipano  and you can use it online
.

In a doc I've written in PT_BR I also list many sites that can receive the
erect upload and will make your pano available:

   - http://www.360cities.net/
   - http://www.tourwrist.com/
   - http://www.viewat.org/?i=pt
   - http://sky.easypano.com/
   - http://photosynth.net/ice.aspx
   - http://round.me
   - http://plus.google.com
   - http://www.spinattic.com/
   - http://www.picbox360.com/pt
   - https://kuula.co/

I guess google plus also need adequate EXIF info and not only a 2x1 image,
like many other sites.

There are also offline desktop viewers like Panini (which I use frequently
in linux), DevalVR and others.

On Android cell phones I use the Google Cardboard app and you just need to
name your panos correctly (like "PANO_xxx") and put it on the camera DCIM
folder to experience it with VR. I don't know an offline app to navigate on
a 360 image without VR. Anyone?

Re: [hugin-ptx] Samsung gear 360

[Carlos Eduardo G. Carvalho (Cartola)]

I have done that for Ricoh Theta S and my workflow included a first step to
split the frames in two images using imagemagick. Then Hugin could
understand better each file as a fisheye image and stitch it.

I don't have my script here to give you more details. From what I remember:

- separate frames from video
- split each frame in two images
- stitch one pair to use as a template
- stitch every pair with the template
- generate erect video with stitched frames

I didn't do, but I guess its possible to use enblend with fixed mask,
because it takes too much time to stitch every frame having to calculate it
every time.

Doesn't Samsung offer a program to do this? Ricoh theta has its own free
software (for windows) that does this automatically. You can also try it.

If you have more results please publish them here. I will receive a Gear
360 in August.

Re: [hugin-ptx] woa: NO control points added?

[Carlos Eduardo G. Carvalho (Cartola)]

I've tested here in a Linux box and it found 84 control points.

Some suggestions:

1) remove the spaces from them PTO file name

2) update the Hugin, I'm almost sure a few time ago someone published here
a newer windows version

3) Try adding manual CPs and/or use the "Edit CP" at the Fast preview
window, second tab

Re: [hugin-ptx] Re: Enfuse v4.2 question

[Carlos Eduardo G. Carvalho (Cartola)]

I would also suggest that you fuse with enfuse generating a 16 bits image,
like a TIF, and then process it in Rawtherapee, that is also free and can
deal separately with dark and light areas. It is really powerful.
 Nowadays I have practically stopped doing image fusion (also mainly
because of the use of a philopod instead of a tripod) and have been
treating the RAW directly with Rawtherapee. I usually shot a little darker
to then recover the details of dark areas on it.

Cheers,

Re: [hugin-ptx] Automatic Hugin

I would script that in shell to have, for example, a final pto to open in

I haven't done 3D panoramas yet, but from what I've read it looks like you
can't do a few number of images. 12 looks ok, as I've already read that 20
would be a good number. There was a post at facebook where people discussed
the small number possible. Nobody was able to do with 4 and the results
were improved when increasing the number.

Maybe some device like this -
http://cdn.instructables.com/FC0/X56G/HFPTJG8S/FC0X56GHFPTJG8S.LARGE.jpg -
can reduce the shots in half.

I would also recommend a philopod for the nadir. In fact nowadays I
practically only shoot with it, without tripod at all, unless when it is
totally necessary. You can try to use it only for the nadir, and you don't
need to turn the camera down, just turn it enough to an angle that reaches
the nadir and make 2 or 3 pictures around.

The workflow could be like: when shooting with the tripod, use a philopod
to mark the nadir point with a coin or any small object. Do your pictures
with the tripod, then do the nadir pictures with the tripod.

Some videos:

https://www.youtube.com/watch?v=ouOEM4cKKGc

https://www.youtube.com/watch?v=znT-kzOXf-A

And here a forum post where I've suggested the use of a philopod + tripod
in cases where you may need long expositions, for example (it is in
Portuguese, but images can illustrate the idea):

Re: [hugin-ptx] Control points editor / Line detection / Projection of a single image

[Carlos Eduardo G. Carvalho (Cartola)]

Once I thought that a good function would be to select what kind of CP we
wish when using the Edit CP functionality at the Fast Panorama Preview
window. If we could specify if we wish regular CPs, horiz lines, vert lines
or just lines it would be great. For lines we might have to select the
desired image too. BTW, I already thought that it could create points only
on visible images.

My 5 cents of suggestions.

congrats on your effort to port to Mac! I've made the first Hugin port to
FreeBSD in 2004 and now Greg Lehey maintains it. It can be a hard work.

>From the Hugin FreeBSD ports page
 I've clicked
in the vigra dependency
 and
then on its Long description

to reach the Vigra page , where you can
see some binaries available to Mac. Maybe it will suppress the need to
compile it as a dependency.

I've mentioned the FreeBSD ports page as another alternative to search for
the dependencies in a place where they're all mapped already.

Good luck,

 These Mac scripts needs probably some tweaking. Since they were used
 last some dependencies have changes.
 From boost Hugins needs now only boost::filesystem (instead of
 boost::thread we are using std::thread)
 In build-all.sh there are references to glib, lensfun, make, tclap,
 liblcms which are not needed anymore (maybe also libffi - I don't know
 which lib is using it).
 So this needs also some more work.

I batch process all images with the same settings. You can copy/paste a
selected image at the browser, Rawtherapee copies the profile. When I do
that, in some rare cases when I think some other picture is not ok, then I
make it better and copy the profile to the others again and batch process
them.

I've done that a lot in the past, but nowadays I usually do only one RAW.
This is mainly because I'm using mainly a philopod. With a tripod I guess
multi bracketing can contribute to reduce noise and improve sharpness, so I
usually like it. CA can be treated in Rawtherapee, photivo or other tools.
A little CA usually doesn't bother me, but sometimes we get a lot :).

As I've developed a small shell script to put live subtitles on screen, now
I tend to make content at least in two languages. I also have difficulties
to find a quiet place to record my voice, so it also helps on it, making it
possible to record tutorials in places I couldn't before. I've been
thinking of writing also in French when I'm able to record audio in
Portuguese :)

And I've just thought that instead of live subtitles written at the video I
could make the script generate a subtitle file, so people could translate
it! Hmmm, thinking about its workflow...

Bests!

Re: [hugin-ptx] Re: Video tutorials

[Carlos Eduardo G. Carvalho (Cartola)]

Hi Sukima,

hope you have seen also other tutorials I have already made with Hugin and
GIMP. Some are in a Playlist together with these two, but others are spread
in my channel (I guess). I have also a blog (link in my signature) where
you can find many references. The reference page is also in English,
although I tend to produce many material in Portuguese as I think many of
my people have almost no material in this language.

I usually do a first image treatment in Rawtherapee and use 16-bit tifs in
Hugin. The Hugin output I do with 8bits and then do post editing at the
final JPG even when converting to cube faces with Panotools::Script and
back.

>From what you've said I would recommend this other tutorial (included in
the same playlist I've mentioned):

[hugin-ptx] Video tutorials

[Carlos Eduardo G. Carvalho (Cartola)]

Hi,


Hi, I've post a survey recently about which tutorial people would like me
to make about panoramic photography. Here the preferred one on how to edit
the nadir without using cube faces:
https://www.youtube.com/watch?v=5RlNsXHq790 Although I've used Hugin, this
is a general concept that can be done in other tools.

And here another one on leveling a panorama
https://www.youtube.com/watch?v=OVJ6mGQlIxU I've shown 3 ways to do that:
automatically, manually or using vertical/horizontal lines. This has been
the second one on the survey.

Re: [hugin-ptx] images to big?

[Carlos Eduardo G. Carvalho (Cartola)]

It's hard for me to understand what you have done and what exactly is your
problem.

After adding 26 pictures, which steps did you do? What interface did you
use (Simple, Adv, Exp)?

Have you checked control points? Are you using automatic or manual stitch?

Describe your steps in more details and send your hugin project file (PTO)
to help us understand what you've done.

It can also help to inform what Hugin version and what operational system
you use.

Cheers,

video using your equirectangular as a frame and repeating it on the video
for as long as you want it to last.

Re: [hugin-ptx] lens project file

[Carlos Eduardo G. Carvalho (Cartola)]

You don't need a lens project file Michael. You can just fill its values in
Hugin after loading the images. Once you fill the values correctly (another
friend has already mentioned them answering another email from you) you
can, optionally, save a lens file as *.ini for reuse.

Optionally you can also "calibrate" your lens yourself:

Re: [hugin-ptx] How do I install Hugin 2016.1 RC2 on a Mac?

[Carlos Eduardo G. Carvalho (Cartola)]

I might be wrong, as I don't have a Mac nor follow the releases for it, but
last time I've seen the 2014 version was the last one compiled for Mac. You
can try to compile it yourself and maybe contribute with the results for
the community. The source code is usually available as a *.tar.*

If you don't know how to compile, there's no other option than to wait for
a good soul to do that job.

Re: [hugin-ptx] indoor photosphere

[Carlos Eduardo G. Carvalho (Cartola)]

Indeed, taking the indoor pics without rotating around the lens pupil will
bring huge difficulties in stitching, probably making it possible only with
post edition.

You can try to use manual control points to improve it.

Re: [hugin-ptx] still pano from video

[Carlos Eduardo G. Carvalho (Cartola)]

Yes, after extracting the video frames, the process turns into a regular
stitch. I usually extract frames with FFMPEG - which runs under many
operational systems. I guess for windows there is a version called WinFF.

The trick is to get good quality frames. If you extract to a compressed
format, like jpeg, you better defined a better quality than the default.
Under linux I would do that with a command line like this:

ffmpeg -i input_video.mp4 -q:v 2 output-%05d.jpg

Some more information here

Re: [hugin-ptx] Level a panorama in batch

[Carlos Eduardo G. Carvalho (Cartola)]

Hi people,

I've tried here to rotate, then use linefind, then rotate back. The problem
is that the linefind wasn't successful enough to level the scene. It has
found 2 lines, one ok, but the other completely wrong and even only with
the OK one the panorama didn't level correctly, it would need at least
another one. I guess maybe it is a problem of the scene itself. Probably
this approach would be ok for a scene with more clear lines.

If it was ok, I guess the order wouldn't matter Don, as I am treating each
frame separately and not in the same PTO file.

I am thinking in new alternatives. Maybe using a mask to let in the image
only the parts where I know where there are correct lines, although not
easy to "auto find".

Thanks!

[hugin-ptx] Level a panorama in batch

[Carlos Eduardo G. Carvalho (Cartola)]

Hi,

I have a video made with a Ricoh Theta S and I would like to level it.

I've tried to level the first frame by hand and then stitch the other
frames with each predecessor, but it fails after some frames.

Is there a way to level an image using a script? I've seen that "linefind"
only finds vertical lines, but this specific scene doesn't have good
verticals. I've tried and it didn't find any. The scene has a good horizon
line, but the Align inside Hugin also didn't work.

Any suggestions?

Re: [hugin-ptx] Install Hugin via powershell

[Carlos Eduardo G. Carvalho (Cartola)]

I don't know anything about power shell, but maybe you can try the
"portable" version, which will only need to be uncompressed. Then you will
probably be able to set other things with power shell, like putting the
binaries in the path and configure possible menu items or desktop icons.

The 7z version only needs to be extracted:

Re: [hugin-ptx] Create 360x180 video after stitching

[Carlos Eduardo G. Carvalho (Cartola)]

You can consider each panorama as one video frame, so you just need to join
them in a video format. You can do that with mencoder, ffmpeg, avconv or
many other tools.

I guess another friend here already answered about panini. It is not
anymore in any actual repository. You would have to really compile it. Here
is an old reference I've wrote about it:

http://www.cartola.org/cartola/index.php?title=Installing_Panini

You might need to update some steps. I have it running in a Linux Mint
17.x, but I really don't remember how I did it.

Re: [hugin-ptx] Re: Requires HUGIN Server Process expert

[Carlos Eduardo G. Carvalho (Cartola)]

Hi, one problem is that I'm too busy nowadays and the main problem is that
I can't make a good automatic stitching with your images. I don't even know
if it's possible. As far as my limited expertise tells me, it is not
possible to solve this level of parallax using hugin. You are taking
pictures of very small places. When I have this level of parallax in my
pictures I just solve the errors with manual stitching and a lot of manual
post editing in GIMP.

Bests,

Re: [hugin-ptx] Re: Requires HUGIN Server Process expert

[Carlos Eduardo G. Carvalho (Cartola)]

In such small places parallax will be always a problem. Ok, you have a good
point on trying do get results as good as in autopano, but couldn't you
afford a robotic head to make pictures with no parallax? I've bought one in
France in 2012 for 220 euros, plus the device to control it with bluetooth
for more 55,00. It is a Merlin/Orion, just like the one autopano developers
sell in kolor.com site. As you can afford 4 cameras I just thought you
could think of it.

Some suggestions I would try to make better stitching of your pictures
(maybe you should tell us what you're already trying, so we could think on
how to improve it instead of think from zero):

- are you setting vertical lines?
- try to set a different lens for each image, so the optimization can set
different lens values for each. If you get a mess, try to set different
lens only after previous optimizations
- try to make progressive optimizations, like first y, p, r, then y, p, r,
v, then y, p, r, b, then y, p, r, v, b, then maybe try to set control
points again, then optimize Everything without translation

Bests,

Re: [hugin-ptx] Re: Requires HUGIN Server Process expert

[Carlos Eduardo G. Carvalho (Cartola)]

Surely you could use panohead, just change your camera too :)

With a fullframe DSLR sensor camera and an 8mm lens you would cover the
full visual sphere with 3 images and wouldn't have parallax.

But ok, if you don't wasn't or can't by that I can understand.

I've tried to find your 12 images set, but it looks like the folders in
your link are empty.

Have you tried the approach I've suggested? A more useful information you
could give us is your stitching workflow in details or maybe the script.
You can also find many scripting hints in the list archive.

It created the panorama here with a smaller size (5700x2850) then the one

Is it? Well, I guess I've misconfused that. I use to use enblend, but as it
appeared "built-in" there I thought that it was the default.

Sorry for other failures in my steps. The thing is that I never use the
Simple interface and my preferences are already customized :)

You see John? How good it is to share this things in public? Many other
opinions and knowledges :)

Re: [hugin-ptx] Paid Help Wanted with Hugin OSX 2014

[Carlos Eduardo G. Carvalho (Cartola)]

Hi John,


I've downloaded your images and I've made a fast successfull stitch here.
You must first tell Hugin the correct lens parameters. Here the steps I've
made in Hugin 2015 (which can probably be repeated at the 2014):

- Loaded images in the wizard first button
- Certified that the lens is a "circular fisheye"
- Met "8" at the "Focal lenght"
- Certified that the "Focal lehght multiplier" is "1"
- Activated the Expert Interface (Interface / Expert)
- At the "Masks" tab changed to "Crop" sub tab (tabs below where there is
two tabs: Masks and Crop)
- Selected all images and put the circle around the image, excluding the
black border (you probably have to drag a little at the border of the
rectangular image to make the inner circle appear and be dragable)
- Back to the other window (Wizard), click the "2. Align.." button

And that was all. Then just finished by clicking the third button. It's
maybe a better choice to go to the "Stitcher" tab at the Expert window to
choose other options, like:
- Calculate optimal size
- Blender: enblend (will do a smoother blend)
- save directly as JPEG

I usually do other things to make a better stitch, but those are manual

Re: [hugin-ptx] Re: Paid Help Wanted with Hugin OSX 2014

[Carlos Eduardo G. Carvalho (Cartola)]

John,

if you're going to deal with a repeated workflow you can automate hugin
with a script or python interface. The other tools won't give you this
flexibility and you can give the script ready made for your students.

I really believe this is not necessary. I think, as I've already told you
at facebook, that you just didn't configure correctly the lens. The second
time I've loaded your images, hugin already recognized it (but not the crop
circle) and did a correct stitch.

If you insist with Hugin you will maybe see that it can be a little hard at
the beginning, but I think it gives wider possibilities than other
softwares.

And you might also consider using GIMP, Rawtherapee, Photivo, Darktable,
Shotwell and other free software instead of Photoshop + LR :)

Re: [hugin-ptx] create cubic projection from 360 degree pans shot with phone?

[Carlos Eduardo G. Carvalho (Cartola)]

Hi,

maybe hugin is not the best tool to convert to cubic. You can find tools
easier to use to transform circular (equirectangular) to cubic, like
Panotools::Script tool "erect2cubic", among others. But you can do that
with hugin too.

The second is a stitch task, which can be stitched with hugin. If you have
never worked with hugin maybe you better get familiar with it, cause I
think this is gonna be a very manual stitch.

Re: [hugin-ptx] Re: Settings for panoramas inside buildings

[Carlos Eduardo G. Carvalho (Cartola)]

I've taken a look at one set of images.

IMHO, I would say that you will have to stitch them manually and each
panorama will require a lot of work and post editing to correct parallax
errors.

In a next time try also to fix camera settings manually and don't change
them between shots, including WB. Maybe a simple philopod would give you
less parallax.

Usually I do the opposite and I've always seen that a panorama should be
shot in manual mode keeping the same settings in all pictures exactly to
allow a better stitching.

To deal with big light differences I usually do multiple exposure and post
fusion of them or take RAW pictures measuring light in a medium light point
of the scene. In any case I also keep the same image treatment on all
images that will be stitched together.

Re: [hugin-ptx] Easier batch CP editing would help when stitching stereo pairs

[Carlos Eduardo G. Carvalho (Cartola)]

Don't know if could be a workaround, but you can select multiple points at
the CPs window. Shift and Ctrl work to select multiple points and then you
can delete selected. A bad thing is that you can't see them in the picture
as you select them. The are only shown in the CP tab if you select only
one. A good thing would be if the last clicked were shown in red. With a
big monitor or two monitors it would be very useful.

Re: [hugin-ptx] kodak sp360

[Carlos Eduardo G. Carvalho (Cartola)]

In short: it will do the job and Hugin is able to deal with it.

You can also think about a gopro, with which you will need some more shots
comparing to the kodak, but if the cost is important, you can find the
simpler gopro for 2/3 of the kodak price. I've already done some panoramas
with a gopro, like this:
http://cartola.org/360/2013/10/21/dia-das-criancas-na-praia-em-360-graus/
with 10 pictures (8horiz, 1zenith, 1nadir), handheld (favorable scene for
handheld).

 I thought to use a kodak sp360 to make spherical panos and to reduce the
 number of shots compared to
 a not fisheye lens camera.
 I know this isn't a best solution for spherical pano like a dslr camera
 with fisheye len, but I'm searcing an alternative cheap solution and kodak
 sp360 sounds the best in this case. I wrote to Florian Knorn (author of
 video
 tutorials suggested in learn PTGui page) and for him kodak sp360 it's ok
 to spherical panos, maybe shotting 4 or 6 photos around and one up and
 one down:
 http://www.pano.guru/tutorials/tutorial-1/
 I ask me if is Hugin is ok to make spherical panos and if Hugin supports
 kodak sp360 (...I prefer open source in sw life so I hope Hugin is fine for
 my task). Here some samples shots:

 http://www.photographyblog.com/reviews/kodak_pixpro_sp360_review/sample_images/
 I'm trying to undernstand which Mode Shot of Kodak sp360 is the best to
 get spherical panos. I thinks is Dome Mode.
 Do you have any suggests about this? Someone has the kodak sp360 and Hugin
 is it ok to make spherical panos with kodak sp360?
 This is the manual Kodak:
 http://kodakpixpro.com/docs/manuals/actioncamera/sp360/sp360-manual-en.pdf


 This is specs sheets:

 Tks
 Cheers

 Any good tutorials on tone mapping? If that is what it takes it sounds
 like something that I should learn about.

 And here is the picture of my first try. I used the default on hugin with
 enblend and the program that came with my cannon camera to convert the
 images. I went with the defaults on both and mine are no where close to
 theirs in quality.


 I don't think that tone-mapping is required for this project.

 With 2015.0 and the assistant I got a better result:
 1.) Load images, the stacks are detected and I selected link position
 2.) Change projection to fisheye circular and apply a crop region to get
 rid of the black border (This is only needed one time - you need to stitch
 such a project. When loading the next image set this is done automatically)
 3.) Run assistant
 4.) Select output: exposure fusion from stacks, using enblend+enfuse,
 maybe masking the tripod legs
 5.) Stitch now.

 The window area looks nearly like in the darkest images, but without the
 halos as in the tone-mapped examples.

 When you want to improve these areas you need a darker variant of the
 images where the window areas are better exposed.
 Variant a) shooting a wider bracketing
 variant b) fine-tune the raw-conversion (e.g. select better suited
 parameters for the darkest images to get better looking window areas)

Re: [hugin-ptx] How to stitch windows better(7 comparision panos)?

[Carlos Eduardo G. Carvalho (Cartola)]

I think many of them might be doing what I do myself. I do image treatment
outside Hugin and don't use stacks in hugin. I usually do image treatment
with Rawtherapee and combine stacks with enfuse, the same tool Hugin uses
for that. I just think I have much more control over the final result using
a complete image treatment tool. All the examples I've seen have some kind
of Tone Mapping and Hugin simply doesn't do that. I don't know if Autopano
or PTGui do that, I've never seen this feature on them (I don't use them,
just have tested them a few times).

I will try to do the job using only opensource tools, including the
publication. For those interested, here is the link directly to the post:

 I have been having problems with windows for a while. I have gotten a lot
 better, but I am still not at pro level. Recently a guy uploaded his raw
 cannon files to https://www.facebook.com/groups/panoramicphotographers/
 and people to did their best with them and they got some pretty good
 results.

 I am trying to figure out how to do the same with hugin and I am coming up
 short with regard to the windows, mine get blown out. Yet almost all of the
 others who have done it have good or great windows. So it can be done. Any
 thoughts on the how other than masking in the dark copy?

 The source files are 4 stacks of 3 images in each stack, with one stack
 having 6 (364 Mb) http://www.360imagery.co.uk/temp/pano_test_set.zip

 edges. Any other thoughts on what I could try?

Re: [hugin-ptx] Re: How to reproject equirectangular image correctly?

[Carlos Eduardo G. Carvalho (Cartola)]

It looks really strange. I usually do that with bigger images with no
problem (12000x6000 usually). I also usually don't touch enblend options.

Maybe you can make available for us your PTO hugin file and one original
image for testing. (don't attach). The difference from your steps is that I
usually don't stitch the remapped images, I go for the default option,
which uses enblend. The remapped images only transform originals with nona.

 Hi Christopher,
 You might improve this by using the --wrap option of enblend.  Add --wrap
 to the enblend parameters on the stitch page in the main hugin window.
 See also: panini-renderer; search for 'panini' on sourceforge.  That tool
 might let you rotate and rerender more easily*.


 Thank you Dex for the helpful advice. --wrap looks like just the sort of
 thing for this sort of problem, especially since --wrap=horizontal is the
 default and correct parameter to --warp for this situation.

 Unfortunately, embarrassingly, it seems I asked the wrong question. I
 turns out that the exposure discontinuity I complained about, is rather a
 consequence of the fact that the leftmost and rightmost ~40 pixels of my
 input image are ignored from each edge. On a hunch, I resized my 3584x1792
 input image to 2048x1024, ran the same process in hugin, and got a
 beautiful perfect reprojected image out. Thus I suspect something in the
 process is silently grumpy about the 3582x1792 image size. I will
 investigate this some more.

Re: [hugin-ptx] 2015 beta2 ram usage

[Carlos Eduardo G. Carvalho (Cartola)]

Usually the RAM problem during stitch happens in the enblend step. You can
try the new internal blender by changing it at the Stitcher tab. enblend is
the default.

You can also try to use enblend with -m 3000 option to limit RAM usage,
but it will use disk.

The bigger the final output you configure the bigger this problem will be.
You can also try smaller final outputs. I usually stitch 23megapixel tif
files with 16pp from raw also treated at rawtherapee and I use 4 images to
make a fullsphere panorama. I usually configure the final output as 12000 x
6000 and I can stitch it in 4GB machines running ubuntu. I've had a strange
experience that I don't know if is related to hardware. On ubuntu 14.04 a
specific hugin project took 52 minutes to stitch, while at the same
machine, rebooted with 12.04, stitching the same project took 2.5 minutes.
I couldn't discover the reason. Some people suggested that it was due to
changes on xorg implementation, but I couldn't solve it. At this machine
nowadays I use ubuntu 12.04.

 Hello everyone,

  i have just installed 2015 beta2 from ppa ubuntu next on lubuntu 14.04 64
 bit and found out a strange problem (and also a crash reported in the 2015
 beta2 thread).

 This time i choosed control points manually, it needed a lot of manual
 adjustments but at the end alignment was almost perfect ;) .

 Trying to stich a panorama consisting of 2 horizontal images (16 megapixel
 each one, tiff files developed from raw with rawtherapee) i have found out
 that ptbachergui uses more than 4gb of ram (all i have in this pc) and it's
 incredibly slow (in fact i had to kill it since it was swapping a lot), but
 it took more than 6 minutes without a result.

 Also with that tiff files the preview windows shows wrong exif values
 (68.882 focal length and 0.599 crop factor) while exiftool shows this:

 exiftool DSCF3061.tif |grep -i focal
 Focal Length: 25.6 mm
 Focal Length: 25.6 mm (35 mm equivalent: 38.0 mm)

 I can upload images and pto if needed.

 Thank you in advance.

 2015-05-28 9:57 GMT-03:00 paul womack pwom...@papermule.co.uk:

 When working on a stubborn optimising problem, it is helpful
 to work stepwise.

 To faciliate this, Hugin's optimiser tab had an option:
 Only use control points between image selected in preview window.

 This works well; however, assuming that an optimisation
 gives a good average and standard deviation, but has a high max,
 it is obvious that some duff control points exist.

 Now, the easiest way to get rid of these is the
 Control Points dialog (F3), which can list control points
 in distance order, making deletion quick and easy.

 But this shows ALL the control points.  In a partially
 completed optimisation, the un-optimised images
 (UN-selected in the preview) will have very large errors,
 and this make removing the large(st) errors
 for the selected images very difficult.

 Proposal/Solution:

 F3 should only show CPs for image selected in preview window,
 possibly also under the control of the option in the Optimise tab.

 As it is I have to click in the CP window, to select a pair, and then
 wiggle the mouse in  the other two windows, and this for every pair, as

Re: [hugin-ptx] control point editing/review - feature request

[Carlos Eduardo G. Carvalho (Cartola)]

Are those really necessary? As you have mentioned the little squared zoom I
think you are talking about the Control Points tab. You can somehow to
these things there.

There is a Zoom: select at the bottom right of the right image where you
can choose the 200% zoom factor.

In order not to see the square zoom you can simply put the mouse over the
image. I just couldn't make it vanish from both sides simultaneously, but I
really don't miss this feature as I can look to each at a time and changing
mouse position is really fast.

Hope it helps.

 When reviewing (and deleting) auto generated control points, I would
 very much like to be able to set the view to 200%
 and NOT to have the little contrast-enhanced accuracy-aid
 appear. The enhanced window obscures the context
 of the control point, which is crucial during this process.

 So the feature I want is the ability to turn OFF
 the enhancement.

[hugin-ptx] Hugin 2015.0 beta - not coloring image numbers at the preview

[Carlos Eduardo G. Carvalho (Cartola)]

Hi, I am running Hugin 2015.1.0.41e868c40876 on a Linux Mint box. Have just
updated the package that showed the version
2015.1.0+hg6958+dfsg-0ubuntu1~trusty while installing.

I have noticed that one function I use is not working as before. At the
fast preview window I use to identify images with the mouse cursor +
pressed control. When the ctrl is pressed the mouse cursor makes the images
colored and you can identify their numbers by the same colors on the number
list that stays above the preview. The images at the preview are getting
colored ok, but the numbers don't, so it is getting difficult to identify
what are the image indexes I want. I use it to make masks and additional
control points for example.

Thanks,

Re: [hugin-ptx] Converting a single image to a particular projection

[Carlos Eduardo G. Carvalho (Cartola)]

Activate the advanced or specialist interface (at the Interface menu item)

I suppose you are using the simple interface, where the wizard works like
what you've described.

 Hi,


 I'd like to convert a single equidistant fisheye picture (Peleng lens on a
 Nikon D7000) to a equirectangular panorama, so there's no stitching
 involved. However, it seems that I'm not able to create the panorama as
 that button remains inactive in the assistant tab.

 Am I trying to do something that isn't supported by Hugin? Or how should I
 go about it?

 Thanks in advance,



 Kristof

Re: [hugin-ptx] leveling horizon commandline

[Carlos Eduardo G. Carvalho (Cartola)]

Hi, when I've made a script I have levelled my pano finding vertical lines
with the linefind command.

You can run it on a pto file using the same pto as output, like:

linefind -o file.pto file.pto

You can also run it on one image at a time with -i option inside a loop:

linefind -o file.pto -i $image_number file.pto

where $image_number goes from 0 to total images - 1.

 Hugin 2013 gets the right result, hugin 2014 doesn't. With hugin 2014 i

Another option is krpano (http://krpano.com/examples/objects/), that is
also capable of publishing the final pictures, that could, indeed, be
aligned with Hugin, but much probably using manual control points and
generating remapped images as frames - a non usual workflow.

 Hi all,

 the default branch of Hugin contains already a lot of changes (bug fixes,
 speed improvements, refactoring) and some new features.
 But for doing a release of 2015.0 we need a release manager who takes care
 of mainly the organisational aspects. But he/she should be capable to
 compile Hugin on its machine for testing purposes and for creating the
 source packages. The process is also described at the wiki
 http://wiki.panotools.org/Development_of_Open_Source_tools#Release

 Are there any volunteers who want to help with that task? Some people have
 already offered a helping hand for this process (in an off list
 conversation), so he/she will not be on its own.

Re: [hugin-ptx] How to create a virtual tour with hugin?

[Carlos Eduardo G. Carvalho (Cartola)]

The free softwares I know that can be used to publish an equirrectangular
panorama or a tour made with many of them are the Salado Player, which
usually I use toguether with #VR5 to make it compatible with iThing
devices, and PanoVisu, a GUI tool to publish using HTML5. This last one is
much easyer to work with, but I haven't publish with it yet. I don't know
how compatible with different devices and browsers it is.

http://panovisu.fr/

Hope it helps. I can help with Salado also, but it is more difficult to
work with it.

 Did you use erect2qtvr to generate a .mov file from your
 equirectangular panorama?

 erect2qtvr creates QTVR files, which were once the only way to deliver
 interactive panoramas over the internet, but you needed Apple's Quicktime
 player to view them (Pablo also wrote a nice Linux viewer called Freepv).
 But Apple dropped all these 'multimedia' bits from Quicktime, so QTVR is
 pretty much useless at this point.

 You can load a panorama into a 3d animation tool, such as Blender, turn
 and zoom the camera, and generate a normal video, but you need Hugin to
 stitch a proper panorama first.

 Usually 'virtual tour' refers to a series of immersive panoramas linked
 together. There are lots of solutions for doing this, but Hugin only
 creates the individual panoramas, it doesn't link them together.

Well, this is a quite broad question... you could check the many tutorials

And, in case of errors, report also your operational system and exactly

Re: [hugin-ptx] Aligning two images one on top of another

[Carlos Eduardo G. Carvalho (Cartola)]

Don't know if you are using windows, but if you have command line skills

two aligned images from the originals.

Inside Hugin you can use the Remapped images to obtain the original
images aligned.

  Try ticking one of the 'exposure corrected' or 'exposure fused' boxes
 under 'Panorama outputs' in the Stitcher tab. You'll get transformed and
 scaled .tiff files of the original scans.
 
  Import them in Photoshop/Gimp, increase the canvas of both images, align
 them manually (shouldnt be too hard as the distortions are identical now)
 and do your operations.  Perhaps in the log files you can find the exact
 shifts needed for perfect alignment.
 
  I am sure there is also a trick to obtain a two-layered TIFF file with

   Knowing that Hugin is made

   I have two scanned images (scanned
  from a roll film). Image A is larger

  it onto image A.
 
   To do this, I need to have both images

   Problem is that as as expected with
  any scanned image, the cropping is
 
   slightly different, there are minor
  distortions etc'.
 
  
 
   I wanted to use Hugin to create a file
  based on image B, that is aligned
 
   according to image A (meaning:
  it's the same size as image A and all
 
   elements in it are aligned correctly).
 
  
 
   Can Hugin, or any of the tools that

   Thank you so very much!

  I think you can do this, it's part of

  what you are doing is some
 
  form of HDR/exposure blending.

Re: [hugin-ptx] Wrong stitched photographs in Hugin

[Carlos Eduardo G. Carvalho (Cartola)]

Try a more advanced interface to make it sure that all lens were corrected.
From your 5th image it looks like only one image got corrected. Using
advanced or expert you can still use this same automatic workflow in the
fast panorama preview window. On the other window that will open select all
images at the Photos tab and correct the lens parameters at the bottom.

If it doesn't solve, try to attach the PTO for us.

 I tried stitching photographs taken with a Nikon D600 + Nikon Fisheye
 10.5mm + Nodal Ninja III.

 The pan head is perfectly calibrated to rotate at the point of no
 parallax. The photographs were taken in RAW, then were exported in JPG,
 preserving all metadata.

 Below I reproduce the steps I did:

 1. I open Hugin 2013.
 2. I select the simple interface.
 3. I load the four images.
 4. I notice that Hugin does not correctly detect the type of lens, and the
 multiplication factor of the camera.

Re: [hugin-ptx] Grid Stitching Senior Design Project

[Carlos Eduardo G. Carvalho (Cartola)]

I have already found vertical CP to stitch a zenith image in a spherical
panorama using cpfind in a script. I agree with Terry's suggestion to try
it.

You don't need to generate so many temporary files, unless you want them
for something. You can just point to the same file as input and output,
like:
pto_var --opt y,p,r -o output.pto output.pto
autooptimiser -n -o output.pto output.pto

Cheers,

 Hello!

 I am a senior computer engineering major working on my senior design
 project in image stitching. For this project I am working with stitching
 hundreds of rice field images with GPS metadata included. I have decided to
 give PanoTools a shot for stitching these images, and have made a prototype
 script for stitching 2 images together. Here you can see the prototype BASH
 script:

 pto_gen -o to_stitch.pto -p 0 -f 10 $1 $2
 autopano-sift-c output.pto to_stitch.pto
 pto_var --opt y,p,r -o output2.pto output.pto
 autooptimiser -n -o output3.pto output2.pto
 autooptimiser -m -o output4.pto output3.pto
 pano_modify -o output5.pto --center --straighten --canvas=AUTO
 --crop=AUTO output4.pto
 echo optimiser done, see optimised.pto. creating make
 pto2mk -o output.pto.mk -p output_stuff output5.pto
 echo done creating make, see final. now making.
 make -f output.pto.mk


 Using this script I am able to successfully stitch two rice field images
 left to right. The problem comes when I rotate each of them 90 degrees. It
 seems that autopano-sift-c can't find control points vertically. It is my
 understanding that SIFT algorithm alone should be able to identify control
 points, but I'm guessing this implementation must have been optimised for
 panoramas.

 So my question: Does anyone know a way to get autopano-sift-c to detect
 keypoints vertically? If not, is there another keypoint finder I should
 look into?
 Also if you see anything in this script that looks dumb or unnecessary
 please let me know.

 Thanks!

Re: [hugin-ptx] Re: Object Recognition

[Carlos Eduardo G. Carvalho (Cartola)]

Do you have an example pair of images? Probably hugin can do that, it is
just a case of guarantee that the images are configured with different
lens. If they have good candidates for control points hugin probably can do
that with the automatic workflow. Have you tried?

 Hello,

 You are probably looking for an image processing library.
 You could take a look at OpenCV scale invariant features.

 Hi

 New here and to this software, could anyone help me with how to make
 hugin recognize an object from image 1 in image 2.

 Example: Image 1 is a small extract image originally taken from image 2.
 Image 1 has been increased in size and the resolution is now poor. Would
 like hugin to locate the place in image 2 where image 1 was originally
 extracted from.



 Thanks for any help or advise.

Re: [hugin-ptx] Re: Change the number of lens automatically

 In case b) feeding images from different focal lengths to the same work
 does not work - it does not provide the correct remapping.


Doesn't it? I have just stiched a panorama in which, by my mistake, I have
rotated the lens zoom ring and changed the zoom from 12mm to 9mm and the
stitch was ok. As you said, it automatically set two different lenses and
correctly did optimization and stitch. So, I didn't understand why did you
say that it doesn't provide the correct remapping.

Re: [hugin-ptx] Re: Hugin Translation x PTGui Viewpoint optimization

2014-10-14 19:51 GMT-03:00 Brandon bran...@flyingtsalers.com:

 Could a person stitch the pano together with everything other than the
 handheld down shot. Stitch it take the result and turn it into a cube. Then
 take the floor side of the cube and using the mosaic stuff that hugin has
 put the hand held down shoot onto the floor side of the cube?

 I have not had a down shot bad enough that I have done it yet, but I have
 wondered about it and if that would be possible.


This is more or less what I've done here:
http://cartola.org/panoforum/viewtopic.php?f=19t=32 - it is in Portuguese,
but the images show the workflow. A cube and a displaced nadir with
perspective corrected using vert and horiz lines. It works perfectly, but
nowadays I am frequently using no tripod.

Re: [hugin-ptx] Hugin Translation x PTGui Viewpoint optimization

[Carlos Eduardo G. Carvalho (Cartola)]

2014-10-14 18:11 GMT-03:00 Bruno Postle br...@postle.net:

 The Hugin mosaic mode fits images to a flat plane, usually in the middle
 of the output panorama.  So if your mosaic is a floor rather than a wall,
 you need to arrange your output panorama so the nadir is in the centre of
 the canvas - This is probably not what you want a spherical panorama to
 look like.

 Hugin 2014.0 has Tpy and Tpp parameters to tilt this plane and put it
 anywhere you like - This is what you need.


Tks Bruno.

Re: [hugin-ptx] Re: Hugin Translation x PTGui Viewpoint optimization

[Carlos Eduardo G. Carvalho (Cartola)]

2014-10-14 16:07 GMT-03:00 panostar houghton.jo...@gmail.com:

 Not long ago I worked out a technique for stitching hand held panoramas
 (no philopod or plumb line) using viewpoint correction in PTGui that has
 been surprisingly effective.  Normally, a hand held nadir shot aligns with
 images shot from a tripod mounted camera without any difficulty, using vp
 correction for the nadir alone.  When all the images are hand held, the
 horizontal row of images won't themselves align with each other well enough
 to accept the nadir image alignment.  The trick I have devised involves
 adding the horizontal row of images a second time into the project.  The
 additional images are treated as nadir shots and aligned with viewpoint
 correction applied.  Image areas that are not part of the flat floor/ground
 are masked away.  A few control points around the edge of this floor area
 are assigned to link it to the normal row of images.  The features used for
 this are in the reasonably far distance and therefore relatively immune
 from parallax effects.  The floor areas in the normal horizontal row of
 images are masked away.  The combined sets of horizontal images then
 provide a nicely aligned floor area to which the handheld nadir shot can be
 aligned very well.

 This technique can be startlingly successful.  This is the first panorama
 I tried this technique on:

 http://www.johnhpanos.com/spherical/peterbor2/peterbor2.html

 Paving is notoriously difficult to stitch well in hand held panoramas, yet
 what you see in the above panorama is straight out of the stitcher without
 any Photoshop post processing to correct minor glitches (other than coping
 with 3D features like people, who are not part of the flat floor and
 therefore distorted by the viewpoint correction transformation).

 I should think the same technique could be used in Hugin too.

 John


Tks John. I guess I've already seen a page where you describe this
workflow. Quite interesting. In my workflow I don't have a nadir picture. I
am usually doing 4 pics with pitch variation and I am searching for ways to
minimize eventual parallax errors. I use to see Zeljko Solectic panos and
he frequently mentions the use of viewpoint correction in similar
situations.

I hope I will have time until next week to study all options suggested here
and if I come to any conclusion I will share here.

Thank you all!

[hugin-ptx] Hugin Translation x PTGui Viewpoint optimization

[Carlos Eduardo G. Carvalho (Cartola)]

Hi,

recently I've been doing many hand held panoramas with a philopod. Some
other people who do the same and use PTGui usually make comments about the
PTGui viewpoint correction. They say that it makes very good results,
allowing more tolerance in the philopod rotation.

In this page http://www.ptgui.com/examples/vptutorial.html there is an
example of a displaced nadir picture being added to a stitch using this
optimization. I guess I've already done that once optimizing translation of
the nadir picture, but usually it works better if I work with it separately
adding vertical and horizontal lines to correct its perspective and then
add it to the complete stitch.

I've been trying to use translation to improve a final result of a handheld
panorama, but it always mess up everything, making the result worse that it
was, showing like a quad, like this:


​
No matter what I try, only one picture, all of them, only some translation
parameters or all with or without positions, it never improves the stitch.

Is there a way to use it in spherical panoramas? Would it be the viewpoint
correction shown in PTGui? Could we have a function like that in Hugin?

Thanks!

[hugin-ptx] Hugin 2014.1 for Windows

[Carlos Eduardo G. Carvalho (Cartola)]

Hi!

I am giving a course in a social project here in Brazil. At the lab I have
installed a linux and compiled the 2014.1 hugin version. What I like most
is the Edit CP funcion in this new version.

The problem is that the students usually have access to Windows computers
(those who have access to any) and I don't have the skills to compile hugin
on it. Does anyone have a windows compiled version of this 2014.1 or knows
where I can find it?

As long as possible I also try to give some feedback to the community, as
this video made for educational purposes for the understanding of the NPP
point and how to find it:
