you really should find and delete the
errant marked points. That task is something you need to learn how to
do. In time you will learn what parts of an image are likely to fool
the automatic point generators. Sometimes it is best to manually
enter all the marked points associated with the rotated picture.
This post did contain valuable advice but I'm often dismayed by the
condescending treatment ("in time you will learn...") in this group of
users that provide good input on making Hugin better. There's no
better way to make sure that Hugin stays an obscure and difficult
to use tool for enthusiasts only.
To do
that you probably will want the picture properly rotated in the
Control Points tab after it has already been improperly rotated by
Hugin and after you have deleted the marked points for that picture.
Yes, exactly. Autopano-sift-c loves to line up control points along
the edges of the images or in clouds and making ridiculous matches.
To find them you open the control point window, sort it on bad matches
(you have to click *twice* on the column although this should really
be the default sort order!). Then you click on the worst point.
This takes you to the control point window.
Now the images are rotated in different directions, some
even upside down. How easy is it to find the bad points?
Naturally you would like to rotate the images then and there.
One could have used Celeste if it didn't have the habit to remove
only half of the cloud points and then half of the good points as well.
Rotating pictures is simply accomplished by manually changing the
"roll" value in the Images tab for that picture. Select the image in
the Images list and then type in the new roll value. Pictures appear
90 degrees clockwise rotated in the Control Points tab when the roll
value is 45 or greater. Pictures appear 90 degrees counter-clockwise
Could you imagine how frustrating it would be in Irfanview if you couldn't
press R/L to rotate the image in front of you, but instead you would need
to go to a different window, search for the image file name, click on it,
then you naturally can't change the roll value right there, but you have to go
down to a different window, click on the roll field, then think about what
value you need to enter there (-90, 0, 90, 180) without immediately
seeing what effect it has. Then you go back to the image display window
to check if you happened to use the correct value - if not, go back to the
other window, etc. And then repeat this for several images in your pano.
Since I started using Panomatic I no longer have these problems. So I offer
this as advice: download Panomatic, unpack it somewhere. In the Hugin
Preferences go to Control Point Detectors. Click on Panomatic and Edit.
Browse for the EXE. I use the following options:
--fullscale -o %o %i
Since Panomatic is so fast I can allow it to work on my fullscale 12M images
and it then does a much better job of fine tuning the control points than Hugin
does.
(Although Hugin does a much better job than Autopano-sift-c.)
Set Panomatic as Default.
Your mileage may vary - I just do cylindrical panos from rectilinear
images, no sphericals.
