Still..... I just scetched the way I ran into this item. More
"plausible non-user-error" situations could arise. For example, my
camera doesn't rotate the image, but just uses the exif tag to
indicate which side is up. How about a camera that does the lossless
jpeg rotation itself? And if you're calling me rotating my camera for
a second row a user-error, I want to say that there are good reasons:
It takes about 16 images to make a 360 pano in portrait mode. To
augment that with some extra visual information in the "down"
direction, I need only 5 more images in landscape mode. That reduces
the complexity of the hugin process enormously.
Anyway, with a simple preprocessing trick in hugin, it shouldn't be too
hard to make this work.
When an image is "portrait" (vsize > hsize), rotate it by -90 degrees
internally, and set the default roll parameter to 90. Nobody would
notice.
Now, the "hfov" parameter always refers to the longest side of the
image. (and might need an eventual rename....)
And linking portrait and landscape images from the same lens becomes
easy.
Roger.
