I use self-compiled 2024.01 on Debian Bookworm.
*Images get left out of generated EXR files*
When I make a panorama, I usually use the Autocrop option (not
HDR Autocrop or Autocrop Outside) and have Hugin output both a
TIF and an EXR version. Quite often now, the TIF has the full
panorama, but the EXR version is missing the first image when
only part of the first image is included in the crop. I would
think that Hugin would include all parts of images that are
included in the crop area in both formats.
Ideas?
No. Essential informations are missing. You are outputting a HDR
pano, right?
Sorry. Yes. The TIFF is 16-bit, the EXR is its usual color depth.
32-bit floating point, I think.
One time type set the EXR and then to TIF?
I usually select both the TIF and EXR formats for output at the same
time. They're using the same crop.
Which images are affected?
Usually the first image in the panorama. Sometimes the last image.
Very rarely, I'll spot a black notch at top or bottom somewhere in the
panorama. The TIFF version shows no notches
Manually adjusting the crop to exclude it eliminates the notch, but I
wonder if they appear because Hugin left out an image in the EXR
panorama that covered that notch, but didn't leave it out when
producing the TIF version of the panorama.
The remapped single images, the stacked images or the blended images?
The blended panorama image. Although I suppose I can check to see if
it's actually outputting the missing single images or if they're
coming out wrong. In the blended panorama image, the missing images
just show as black.
If the latter, which blender used: enblend or the internal? When
enblend which version?
Thanks. I only use enblend, v4.2, which comes with Debian Bookworm.
I just did a test of a 3-frame panorama, enblend vs internal blender.
Results:
Enblend: Last image on the right end of the panorama is missing. That
part of the panorama shows as black.
Internal: No image is missing, but the image colors are all wrong and
there's a noticeable straight seam between the middle frame and the last
frame.
*Hugin PTO Generator misreads focal length information*
I often output a series of TIF images using RawTherapee, select
those images and use the Send To Hugin PTO Generator, then open
the resulting PTO file. When I checked the focal length settings
in the generated PTO file, the focal lengths will be noticeably
off. I just checked now; images with focal lengths of 28mm were
read by the PTO Generator as 46mm focal length.
This throws off subsequent alignment, barrel distortion, and
other corrections.
If I start a new PTO file, then drag and drop the same images
into the Hugin Photos tab, Hugin reads the focal length
correctly. Why is the PTO Generator misreading it while Hugin
gets it right?
Ideas?
Both program use the some code. Maybe you set the field of view in
your call of pto_gen (- -fov switch)?
Check of progress messages from pto_gen. Or run pto_gen from the
terminal and check the output in the terminal.
I did that. Running pto_gen *.tif without any other command line
options produced a PTO file that shows image focal lengths of 57mm
when opened in Hugin, for images that were shot at 35mm. My camera's
crop factor is 1. It's a Sony A7R IVA, 61-mpix full-frame.
I've never used any command line options with pto_gen. I just select
files, right click, and pick Open With > Hugin PTO Generator. Is there
some place where such options might be set?
If it is still wrong, provide a sample image for checking.
At 270-280MB per image, they're a bit large. Here's a link to one:
https://drive.google.com/file/d/109neMWTMHWKZjOCobESej7raZ5EM7Ivu/view?usp=sharing
Note that Hugin reports the correct focal length when that image is
dropped into the Photos tab.
Thanks again!
