Re: [hugin-ptx] Mac builds of Hugin

[dgjohnston]

If you’re still looking for feedback on the Hugin-2023.0.0_GPUFIX.dmg build  …  
I just tried it out on a simple file and it works great. The blending before 
created intermediate images with the left side all wonky.

Apple M1 Max, 64GB,, macOS Version 14.2.1 (23C71)

Re: [hugin-ptx] Hugin 2023.0 beta 1 released

[dgjohnston]

To test the GPU I ran a set of images that were in a previous Hugin mail chain. 
18 images, 99MB each, 3307x4961.
My machine is a MacBoo Pro, M1 Max, 64 GB with Ventura 13.6

The GPU did the creation faster (3:07 minutes down to 1:22) but the image was 
garbled. Here are the images with GPU on and off. If you want full size images 
I can send a link.

Re: [hugin-ptx] Multi-row panorama

[dgjohnston]

Greg, thanks for the additional information. The images in this set are well 
suited to the quick run though using the Fast Pano Preview because of the 
randomness of the rocks, trees, and water. It’s hard to detect any minor 
discrepancies like one would with images of manmade structures. With those the 
iterative process that David covered works well to get the best alignment.

I don’t know why David’s version of Hugin wasn’t able to find connections 
between so many images. He used 2022.0 and I’m using 2022.1 (listed as 
pre-release).

1. Another reason that Hugin might be coming up with the “image stacks” is the 
difference in shutter speed of the images … they run from 1/125 s to 1/500 s 
(but I don’t know what Hugin is basing its decision on).
Stanley … I’ve seen many suggestions that pano images be taken in manual mode 
with the settings base on the brightest part of the image. Also, keeping the 
white balance fixed might help the colour tinting that shows up.

2. After Align, I get a mean error of 5.5 pix with max 38.6.

I received the same colour tint issues that showed in David’s stitched image. 
The top-right corner has a green tinge.

Yes, same here. Under “Appearance” in the Mac System settings I changed between 
Light and Dark and the text is readable.

Now it’s just the big ugly 1, 2, and 3 … (smilie face) … seriously that’s not 
an issue.

What’s missing also is the “lens type” and “Focal length” etc. between the 1 
and 2 buttons. The drop down is connected to the “Load Images” button so it is 
not obvious.

Re: [hugin-ptx] Mac builds of Hugin

[dgjohnston]

Dudek53 … additional testing of various size PTO file I have is showing a time 
reduction of 28% to 30% with your load of hugin for M1.

Will you be doing some additional testing on the graphic interface for hugin 
that I sent previously?

Re: [hugin-ptx] Mac builds of Hugin

[dgjohnston]

I’ve done some testing on older .pto files I have. They seem to be running 
similar to the previous versions of hugin.

One of the largest .pto files I have took 39 seconds to stitch on hugin 2022 on 
my Mac and only 28 sec using your compiled hugin 2023 (about a 30% reduction).

I’ll try some testing by redoing the larger set of images that I have and see 
if the interface is usable with the problem I highlighted in my last email.

Thanks for the work you’ve done on compiling this for the M1.

After having to create an Atlassian account to login and access bitbucket, I 
get the error message "You do not have access to this repository.”
Is there a less intrusive way to access this download?

Re: [hugin-ptx] Shooting Panoramas in Tight Spaces

[dgjohnston]

Here is an image of something I did a few years ago that sounds similar to what 
you may be trying to do.


If’s made up of 12 images. I moved along across the street from these buildings 
trying to be at 90 degrees to each “section” of the buildings; hoping to reduce 
any parallax problems later in hugin. I stitched the images together then used 
masking to cut out anything of the images that wasn’t part of the “section” 
straight across from where the picture was taken.

If you want to download and see the details of how I did this here is the link 
to the folder with the images and hugin files.

Re: [hugin-ptx] Mac builds of Hugin

[dgjohnston]

Also just tested the 2022 prerelease (MacBook Pro with M1 chip).

Would run … got a message "The application “Hugin.app” can’t be opened. -47”.  
I was however able to the Hugin from the “Contents/MacOS”.

Seemed to run good after that.

Thanks again Max.

Re: [hugin-ptx] PyImageFuser 0.5.0 released

[dgjohnston]

Hi Harry,

Yes I have used the Contents/MacOs directory before to get an application to 
run properly … but I hadn’t thought about testing PyImageFuser that way.

But … I gave it a try from terminal and received:

…..-MBP MacOs % ./PyImageFuser &
[1] 31277
…..-MBP MacOs % 
[1]  + killed ./PyImageFuser

Just after the 31277 was listed a pop-up window gave the same error about Py 
being damaged.

Harry, I have an M1 based MacBook Pro and I have Rosetta 2 install to simulate 
an intel 86. When I try running you PyImageFuser for Mac OS I get the error 
message: "“PyImageFuser.app” is damaged and can’t be opened. You should move it 
to the Trash.”

Re: [hugin-ptx] Using align_image_stack for focus stacking

[dgjohnston]

Thomas and Bruno.  Thanks for the feedback.

I had tried the use_given_order but without thinking about putting the images 
in order of front to back focus.
I’m hitting the road tomorrow so I’ll be able to try some real stacking with 
landscape images and I’ll try to ensure that I have a bit of overlapping 
in-focus sections from one image to the next

[hugin-ptx] Using align_image_stack for focus stacking

[dgjohnston]

Hi, this is a link to the test subdirectory I’m using to get align_image_stack 
to process a few files for focus stacking. Don’t mind the laundry, these were 
just some quick test shots I made.
https://ln5.sync.com/dl/1535e65f0/fxrj8uqv-yuw77g77-wf4gv4sy-m4sa6k47 


If you look at the jpg images you’ll see that the files are well aligned from 
the start (I had a tripod with a remote trigger); but I’m testing the batch 
file I created (AlignFocusStack.command). After running this command the first 
tif image is not aligned to the other four images at all and you can see the 
ghosting in the output1.tif file that this creates.

In the DGJVine.pto file you’ll see that there are 9 control points between 
image 4 and image 0 but they are all in the lower left.

These are somewhat blurry images in some areas but that is the intent of focus 
stacking.

I did try adding the -x, -y, -z options to align_image_stack and tried setting 
—core down as low as 0.5 and as high as 0.95 with any success.
I was able to use the Hugin GUI to add control points between image 4 and image 
0, and between image 0 and image 1 in the blurry areas.

Any suggestions on how I might improve on the ability of align_image_stack in 
this situation?

Bruno … thanks for your quick responses on this forum.  It is very much 
appreciated.
1. Am I correct in saying that when hugin optimizes for translation 
that the canvas always stays at 0,0,1 and then the x,y,z values basically move 
the camera position of each photo so that the control points line up as best as 
possible?
2. When hugin optimizes for translation is there one photo that stays 
at Z=0?

Re: [hugin-ptx] New release for mac?

[dgjohnston]

After telling MacOS that everything was okay (and setting Full Disk Access) 
everything is now working on my MacBook Pro
 15-inch, Mid 2012) running Catalina 10.15.7, Intel Core i7 16GB 
memory, Intel HD Graphics 4000 1536 MB.

So you can caulk this up as a great success.

Thanks for putting this together for us Mac users!

Hi Bob … I have a MacBook Pro (15-inch, Mid 2012) running Catalina 10.15.7,

If you need some additional testing of you build I would be willing to test it

Re: [hugin-ptx] [Request]: Resolve confusion between "Distance" and "Correlation"

[dgjohnston]

Before I use hugin I usually use DxO PhotoLab to correct for lens and camera 
body distortion. Does anyone know if DxO uses the Brown-Conrady lens model for 
their routines or anything similar?

In the wikipedia entry for “Distortion” there is one comment about this:
DxO Labs ' Optics Pro can correct 
complex distortion, and takes into account the focus distance.

Optics Pro was renamed to PhotoLab in a previous release.

Also look at DxOMark the company that does the lens and camera testing to 
create the correction modules for lens-camera pairs.

Re: [hugin-ptx] Does anyone have any image sets, particularly ones that don't blend well, that they could share for testing purposes?

[dgjohnston]

Hi Monkey … these are links to some file sets I have on Sync.com 
.  Let me know if they are useful.

Re: [hugin-ptx] An addition for the Hugin Tutorials page

[dgjohnston]

That link is at a second level so I’d recommend that the link be on the 
tutorials page. It would be a lot easier for someone to find … I don’t usually 
think of looking for links inside other tutorials.

Thanks

[hugin-ptx] An addition for the Hugin Tutorials page

[dgjohnston]

Could I recommend that the following link on linear panoramas be added to the 
tutorials page.

https://panospace.wordpress.com/2010/09/19/linear-panoramas-mosaic-tutorial/ 


It’s provides an excellent procedure for an advanced mosaic technique for 
building facades.

Re: [hugin-ptx] Can you calculate position and FOV of cameras using Hugin for 3dsmax?

[dgjohnston]

Terry, you were correct. Here is the link to the tutorial by Yuval Levy:

https://panospace.wordpress.com/2010/09/19/linear-panoramas-mosaic-tutorial/

Richard, take a look at this and see if that provides any ideas for what you’re 
looking for.

Re: [hugin-ptx] Hugin 2019.0 beta 2 released

[dgjohnston]

Thanks for testing this Frederic.  Here are the conditions that I’ve noticed 
when the problem occurs ...
Two different panos I’ve tried.  -  images: jpg, first set:1400x934 (2 images, 
14 control points) and second set: 1000x667 (7 images, 12 to 17 control points 
per pair) … both show same issue.
Zoom - "fit to window” and “50%" … doesn’t happen … at 50% all of the image 
shows in the window.
Zoom - 100% (part of image shows in windows) … happens ... unless the viewable 
part of the images changes (i.e. the preview window is refreshed to 
display/center the control point)

Re: [hugin-ptx] Dimension position parameters TRx Try TRz

[dgjohnston]

Sorry, I’ve exhausted my knowledge on how hugin might be calculating and using 
these numbers; it doesn’t seem to match the theory written up in the links I 
put up.

Would any of the developers / support guys have any thoughts on this for Kai?

Perhaps this link might help … I had to read it very carefully a few times …

If you’re in a plane taking a picture straight down just think from you point 
of view as laying down pointing the camera straight down … so Z is “in” to the 
ground (it’s always relative to what your camera is looking at).
I believe from this then that TRx of 0.521 being 30cm is relative to the 
“Projection Plane” at Z=-1 (and the panosphere radius r=1); r must be at about 
twice (1/0.521=1.919) 30cm or 57.6cm.

Re: [hugin-ptx] Dimension position parameters TRx Try TRz

[dgjohnston]

Kai, is this a 3D object?  I believe Mosaic Mode is meant for 2D images like a 
picture or mural.  A 3D object will introduce parallax errors that will make it 
hard to stitch unless you are really careful in placing control points and then 
masking out any overlaps.

Kind regards from Canada.

I added in the ransacdist parameter and put in the two images at full

I didn’t want to put images up at first in case I was missing something

but one set (5000 wide) works and the other (7000 wide) doesn’t work.

[hugin-ptx] cpfind - no control points on large images

[dgjohnston]

Hi, I running hugin as follows:
2017.0.0.eac5e8cc546e built by Niklas Mischkulnig
MacBook Pro, macOS Sierra 10.12.6 with 8GB memory
When I load in large images cpfind doesn’t generate any control points and I 
get an error message about “Warning 2 unconnected image groups found:[0], [1]”
This depends on the size of the two images I’m using in this pano. The breaking 
points seems to be at about 6043x4033 pixels (each of the two images at about 
24.5MB jpegs). I say “about” because most of the time 6043x4033 works but that 
size has failed at times; and … 6044x4034 fails most of the time but has worked.

Am I missing an image size limitation? I tried searching for this but can’t 
find anything.

Fantastic, thankyou.
Ok I am not sure how to put my replies below the quoted text. But trying.
Is there a program that I can use to assemble multi row 360 views. 
I have a program that does single row 360's (fly arounds) as well as the 
automated hardware that comes as an automated product photography package and I 
sell the imagery commercially. 

As such I apologise for any incorrect terms however my focus is not verbage it 
is simply to find a program that can assemble a presentation of a multi row 360 
that, when it (the program) pumps out an HTML5 or flash image, enables the 
viewer to see 360 x 360. 
That to me means all the way around on more than one plane, like a spherical 
panorama but viewed from the outside of the sphere.
Take for example a shoe. I want to be able to look all the way around that shoe 
along its horizontal plane as well as its vertical plane so I can see the top 
and bottom as if I am holding it in my hand. UX stuff you know. Its all about 
UX in online sales.
Thanks again to all that can help.

Please make sure to reply-all to keep the mailing list in the loop, and

also try to put your replies below the quoted text.



Turntables are completely different from panoramas. The way they work is

by switching between separate, descrete images like a video does. You

cannot "stitch" these images because there is nothing to stitch; they

are each of a different perspective.



Panorama stitching is basically the act of simulating having a wider

lens (or in the case of mosaics, a larger flatbed scanner). A turntable

360, on the other hand, simulates flying a camera around an object.



There is a technique called slit-scan that may be causing some

confusion, as it technically is a form of panorama, however I do not

think it is what you want:



http://petapixel.com/assets/uploads/2016/03/slitscanhead.jpg



In short, you can't stitch turntable flyarounds. You just need a viewer

that can play your normal images in sequence.

It's not surprising that you can see the seams: there is a very serious 
parallax issue in your shots.  See this animated gif that illustrates the 
problem: https://www.sendspace.com/file/231rdz .  You need to maintain a 
constant viewpoint for all the shots, which means rotating the camera about the 
entrance pupil of the lens (the no-parallax point).  See:

Re: [hugin-ptx] align_image_stack running for 3 days

[dgjohnston]

Just out of curiosity why are you using that many images. Do you have 450 
different light levels or are you creating a time lapse video?

I'm trying to run align_image_stack on 450 images of size 4000x3000, with a 
simple command line invocation:

align_image_stack -a aligned -C *.jpg
However it ran 3 days and never finished! Are there options you can use to make 
it faster?

These are pictures of my yard from the same angle, but different lighting

Re: [hugin-ptx] Strings from translation file

[dgjohnston]

I read this as:The loaded images, all the same view but with different exposure 
values (EV), are fused into a single HDR image.
A "stack" because the images don't form a panoramic image but are piled on top 
of each other.

Subject: [hugin-ptx] Strings from translation file 

Hi

I'm having my (new and old) translations reviewed by my local translator group. 
This brought up a couple of questions and comments.

--- Line 495 (da.po) ---

+#: hugin1/base_wx/StitchingExecutor.cpp:303 hugin1/hugin/xrc/pano_panel.xrc:472

+#: hugin1/hugin/xrc/pano_panel.xrc:1260

 msgid "Exposure fused from stacks"

In Danish I can translate the first part as either "Eksponeringsfusioneret" or 
"Eksponering fusioneret", but they have two different meanings which the 
English sentence is ambiguous about when viewed out of context (by someone like 
me who is not into all the technical details). So does this mean that:

- The exposure is being fused, or
- Something else is being fused by help of/in relation to the exposure?

-

--- Line 2205 (da.po) --
+#: hugin1/hugin/ImagesTree.cpp:144

 msgid "# Ctrl Pnts"


This needs to be very short, obviously. Why not use the acronym CP which is 
used in many other strings? (e.g. "# of CPs" or "CP count")

--

+#: hugin1/hugin/ImagesTree.cpp:163

+msgid "Translation remap plane yaw"

I am somewhat in doubt of the meaning of this string. Can somebody 
explain/elaborate?

 I just tested the MP part of enblend on this beta. The monitor program showed 
enblend hit almost 770% on my MacBook Pro. The log file shows "Blender: enblend 
4.1.1”.I didn’t have to use an extension like _mp.
So it works?I am currently compiling Hugin and the other tools with OpenMP, 
they weren't before.  
2. The end of the log file shows the following error:
Updating metadata... Error opening arg file

I checked the contents of 
/Applications/Hugin/PTBatcherGUI.app/Contents/Resources/xrc and there is 
nothing with that name in the directory.

Fixed in the next build. For now you could copy it from 
Hugin.app/Contents/Resources/xrc to PTBatcherGUI.app/Contents/Resources/xrc

If there was a way to keep the source up-to-date then building a release binary

It's vice versa. The source code was still working at Mac OS. But nobody of the

There are some minor glitches which can be easily solved if someone build on

Re: [hugin-ptx] Need help / Feedback on my workflow

[dgjohnston]

My first recommendation would be for you to find out the hyperfocal focus 
distance for your aperture, lens, and camera combination; then use that to set 
your focus rather then infinity. For example your XS with an 8mm lens at f16 
would use a focus distance of 8 meters.

Subject: [hugin-ptx] Need help / Feedback on my workflow 

I need some feed back on how I work with making panoramas. I documented my work 
on my blog and copy/pasted it here. I would really appreciate any advice. 
Thanks.
I often thought my workflow 
was a bit unique. Though recently I found that it is not that unusual. I
 wanted to document the workflow for reference and because I've been 
running into some difficult results in my final panoramas and having the
 steps I took to get there might allow myself to get better feedback 
from others. At the bottom of this post is the final output. For those 
interested I am also offering my original images
 (in RAW format) to see if anyone might be willing to offer advise. I 
don't know if my troubles stem from my Lens, my Camera, my software, or 
my workflow. Any advice would be greatly appreciated.
Taking the pictures
I am using a Canon EOS Rebel XS (A.K.A. EOS 1000D) with a Bower 8mm Fisheye 
lens (A.K.A Pro-Optic, Samyang, or Rokinon). I mount my camera on a Panosaurus
 panoramic head on a tripod. I believe I've calibrated the parallax 
correctly to the best I could through the view finder and by taking 
several pictures with a close object and far object and rotating back 
and forth.I setup the tripod and start taking photos every 60 degrees (six 
images) around, one zenith, two nadir images 180 degrees from each other, and a 
final hand held nadir just in case.I
 use a wired remote shutter to lessen the jitter. I try to sample 
several angles before picking the final settings I use in manual mode. 
Since the lens doesn't have any communication with the camera I manually
 dial in the F-stop. I set the focus to infinity. I use the Raw format.
Pre-processing photos
I used RawTherapee
 to pre-process the Raw files I downloaded from the camera. Since the 
auto settings seemed pretty good I kept them except I set the white 
balance to Shade. I batch saved all the images to 16 bit TIFFs (Uncompressed).
Stitching
I used Hugin set to the Expert
 mode. I'm using version 2014 on the Mac because (at the time of this 
article) it is the only version available for the Mac. In Expert mode I 
add all the images including the hand held nadir. I used the Full Frame Fisheye
 with the Focal Length of '8' which in the past seemed like it worked. 
Mostly guess work here. Anyway Hugin auto populates the field of view 
for me and I go with it.Than I opened up the mask section and 
carefully draw exclusion masks around the tripod in all three nadir 
shots. Finally I click optimize and then open the GL Previw window. And 
everything looked great. I then opened the stitcher view and selected a width 
of 1024
 so the rendering would be super fast while I previewed. I found that 
the GL Preview glossed over some artifacts that you don't notice till 
the final renders.I noticed that the hand held nadir shot 
(although almost aligned) had parallax issues. Mainly since the nadir 
was a set of wood boards. So I gave up on the idea that the hand help 
nadir image was worth anything and deleted it from the image list in Hugin. I 
went back to the stitcher and selected Calculate optimal size and created a 
final version. Now with a gaping hole where the mask for the tripod was.
Editing the nadir
Since I use the GIMP to edit photos I have to convert the 16 bit TIFF to an 8 
bit TIFF using GraphicsMagick:
$ gm convert MillPano.tiff -depth 8 MillPano8.tif
Then I use the Panotools scripts to create my set of cubes:
$ erect2cubic --erect=MillPano8.tif --ptofile=cubic.pto
$ nona -o cube cubic.pto
In the GIMP I edited cube0005.tif and used the clone tool to carefully 
reconstruct the wood planks from the sides (this was challenging using a 
touchpad). Saved it to cube0005a.tif.Finally I reconstructed the panorama:
$ cubic2erect cube000{0,1,2,3,4,5a}.tif MillPanoFinal.tif
And this is the result:




Ye Olde Town Mill


QuestionsIs there a way to get Hugin
 to use a hand held nadir shot when the shot doesn't line up well with 
the shots taken via the tripod head? Would make nadir editing easier.Why is the 
final output blurry? Is it chromatic abrasion? Bad stitching? Crappy 
camera/lens?Download the Original Images. (100MB Zip)

I've always wondered: rotate each frame 90 degrees and now all the horizontals 
are verticles. Run linefind, rotate each frame back, then can you use a script 
to turn "vertical" lines into horizontal lines inside the PTO?
Always thought that rotation was the only conceptual difference between the two 
line types.

I've tried to level the first frame by hand and then stitch the other 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

Any suggestions?

Re: [hugin-ptx] video for Hugin

[dgjohnston]

Is any of this getting to sourceforge? Not sure we have to do anything new, 
either of these two videos would be far superior to what they created.

    Hi,

    I just saw the video Sourceforge is planning to put in the Hugin summary.
    The idea of having a video is good, but the video at 
 should have been prepared in order to show a 
real use case. None of the situations shown in the video are of a real panorama 
editing/stitching (altough the "panorama" with the animals could have its 
purpose), so, they are absolutely misleading. 
    Some of the tutorials, as 
Stitching two photos togetherorStitching Multi-row photos togethercould be used 
in order to create a new video which really shows what Hugin is intended for, 
and how to use it correctly. 
   In few words: please don´t put the video at  
in Hugin project summary!   Luis Henrique

Re: [hugin-ptx] Shooting and stitching to make Giclee prints

[dgjohnston]

Terry, at 6.5m and with a relatively flat painting I can't see there being 
anything to produce parallax errors. Or am I showing my naivety here? Feel free 
to let me know if I'm out to lunch on this! ;o)I'd try experimenting with just 
rotating the camera and doing a normal piano stitch.

I think the camera will be about 6.5m from the painting, but I don't have  
a pano head, hence the current obsession with mosaic mode.
There will be quite a lot of experimental stuff going on at the time, and  
one is to shoot a conventional pano, but I have been thinking that mosaic  
mode would be my best approach.
Thanks for your thoughts on this.

Fwd: [hugin-ptx] Shooting and stitching to make Giclee prints

[dgjohnston]

I also use DxO. And hugin of course. The nice thing about DxO is that 
correction modules are available for most cameras and lens combinations. It 
corrects for distortion, vignetting etc. Then hugin can do its magic without 
having to also correct all that stuff.

I suggest a prime lens rather than any kind of zoom. They are much sharper. 
Many lens are sharpest at f8. Check the literature for your lens. 
Assuming a size of six feet for the largest dimension of the canvas, then at 
300 ppi you will need your output to be 300 x 12 X 6 or 21,600 pixels along 
that side. This comes out to 466,560,000 or about 450 megapixels. You do not 
want to use the entire frame of each source image since the peripheral pixels 
are always less sharp than the ones closer to the center. Even though I use the 
free hugin for stitching, I use a commercial product,  DXO,  for preprocessing 
my images. 

One way to ensure that your images are all taken with the lens pointing 
directly at the portion of the canvas you want is to mark that point with 
masking tape or using two crossed segments of mason twine. Both artwork and 
camera should be absolutely level, something you can accomplish ith a 
carpenter's level. Attach a laser pointer alng one leg of a large 45 degree 
right triangle. Place the other leg of triangle at the intersection point and 
swing it back and forth to see if the laser points at the center of the lens. 
If it does with the triangle oriented along the two perpendicular lines define 
by the mason twin, then your camera is in exactly the right spot. The laser 
pointer method is from watching James Barker, a professional photographer, take 
professional medium format slides. You will have probably do better if you hire 
him to do the photography for you.

[hugin-ptx] Vertical horizontal lines in overlap area?

[dgjohnston]

I have two overlapping images of a building that I'm creating an architectural 
rending from.  I auto generated the control pints and then added vertical and 
horizontal line control points.  In the overlapping area I put the same 
vertical line in both images. It did a great job of squaring up the building. 
My question. Did I have to put the same vertical line on each image or would it 
have been better to put it on only one and let all the other CPs straighten the 
other image to match?

Re: [hugin-ptx] How to best shoot and stitch this?

[dgjohnston]

My best suggestion would be to make sure that you are always at 90 degree to 
the tangent of the centre point of the section of the wall you're 
photographing. And have lots of overlap so you only use the vertical centr of 
each image.

 Because of the considerable curve of the walk I don't think it is  
 possible to shoot it as a linear pano...i.e. many different camera  
 positions. There is a continual change in Trz value, which is small from  
 one panel to the next and may allow a linear pano stitch of 2 images,  
 each with 2 panels, overlapping one panel for a 3 panel linear stitch,  
 but would I then be able to stitch all these linear panos together?
 One other approach I have pondered on, is to shoot a couple of panels to  
 my right and and a couple to my left and stitch as normal, and make  
 about 12 or 13 of these sub-panos, each with one panel overlap on the  
 ends with the next sub-pano. Then try to stitch these normal sub-panos  
 together using the one panel overlap and do these as linear panos, but  
 I'm not sure that the overlap will be enough.
 So, not really sure if any of the above has any hope of success.

The more I think about this, the more I am convincing myself that none of  
the above can produce a reasonable result.

 projection unique or how they are similar to other projections. Now that
 I've written this, it sounds like an entire tutorial could be devoted to
 projections alone.


I think you are right, it could turn into a magnum opus.
I won't have space to cover stuff like this in any detail, and given that

Re: [hugin-ptx] Mosaic of Non-flat surface

[dgjohnston]

A judicious use of masking might be something to check into. Use the overlaps 
to align all the images then mask out most of the overlap at left and right of 
each image so only the central, least distorted, part of each image ends up in 
the final panoramic. Might require more images with heavy overlapping.

One more thing,

I said that the project couldn't get any tougher for my first Hugin project...I 
was wrong.

The second wall that I have to shoot has mirrors on it!!

We can worry about that little problem after we find a solution to the parallax

Hello Donald,

 Matthieu, to answer the question about starting hugin … I mostly start hugin 
 without a project.
 That is I start hugin, load images, do align, and create pano.  So, as soon 
 as I start hugin I'm getting the triangle problem.

  I have made a new build with a possible solution to the problem you
are facing :

http://matthieu.desile.free.fr/hugin/Hugin-Release-2013.0.0.6282-a9991501efd8-10.6.dmg

  If you encounter any other problem with this build, do not hesitate
to tell me,

Cheers,

Matthieu

Re: [hugin-ptx] CHDK

[dgjohnston]

I've used CHDK for years now. Great program. I still use my Canon powershot for 
holidays even though I own a DSLR. I get raw images that way. I've also done a 
lot of time laps using CHDK. It's well worth the effort to learn how to use it.

Anybody use CHDK? How do you like it? What is your experience with it?

I was thinking of buying a little used Cannon ELPH and loading this on it 
to use as an inexpensive pocketable camera that can be used for snapshots 
or bracketed images enfused images and/or panos. From my search, it seems 
there is little mention of it here, which surprised me.

Thanks,
John

If you are in the preview window you have to close it down. That one had me 
stumped the first time.

Re: [hugin-ptx] Hugin 2012.0.0 released

[dgjohnston]

First thanks again for all your work on this. 
When I first read your other email I thought it was a response to a problem. It 
makes more sense now that I've reread it. I had looked at the file sizes and 
worried that the installer being 5.7 MB smaller was missing something.

Re: [hugin-ptx] when to sharpen?

[dgjohnston]

With any image processing it is always recommended that sharpening is the last 
thing you do. Any adjustments after that affect the perception of sharpness 
that the eye sees.

 This probably an FAQ, but I couldn't find an answer: when do you sharpen
 spherical panoramas? Before compositing (i.e. sharpen the original images)
 or afterwards, and if so, using what type of projection (I need to output
 equirectangular in the end)?

I've been experimenting with the projection to do the sharpening on
quite some time ago. I was mainly trying to sort out if there is a
practical difference between:
(i) Sharpening the final equirectangular. In theory this should be a
bad idea due to the messed up neighbourhoods near the poles.
(ii) Create six rectilinear 90x90 images, sharpen those and reassemble
to an equirectangular.

While the difference images showed some very minor differences I was
unable to distinguish the images created by those two methods
visually. I've been sharpening equirects ever since...
