Restating the question: If I were flying over a 2 dimensional world, at a constant altitude, how would I patch those images together?
I'm using some tools right now that assume I'm doing a panorama ("AutoStitch", works for 2 images sort of) or am taking real aerial photos ("MapTiler") and thus somehow screw this up for me. That "somehow" is, I think, the coordinate reference system (CRS) being used by those programs as the model for patching those images together.
The algorithms that use image recognition to patch the photos together are being misinformed in these latter two programs. The first one, AutoStitch works wonderfully for 2-3 images compared with other programs I've used. I can't actually get MapTiler to work, but it appears to be for real aerial mosaic patching. I need one for a 2D world at constant zoom ("altitude").
BOUNTY UPDATE: StackExchange is only allowing me to keep this bounty offer up for 2 more days as of Monday night. I do not have a workable answer yet.
EDIT: To imagine what exactly it is I'm trying to do, consider this. You have a very high resolution image that takes up multiple monitors, you take screenshots of the the different areas of the photo and then want to stitch them together. Its purely rectilinear, no curvature. all 90 degrees down same zoom/distance.
