I get the feeling this is a problem we can solve with (better) code. Planar stitching isn't very hard. Might want a calibration target to determine the lens distortion parameters first and then it should be easy.

thats what hugin attempts to do, but there are still a lot more variables than you'd think. Consistent movement in the x-y plane would help a lot, but you also have microwarps in the surface etc that can be serious issues for image stitching.

hugin tries to take 2 images that you tell it are adjacent, and use a set of key pairs of points to distort, deblur, etc using excess information. You can get somewhat decent results, but not better than what you can get with a hi-res scanner, which should absolutely be doable.

Honestly, hugin already does pretty good job. I did this one with hugin. Not the highest resolution, but it's also a very dense IC (Wii U GPU). Literally just pushing the die around with tweezers. https://marcan.st/transf/latte_stitched.jpg …

how many images did you stitch it out of? because when working with the switch PCB I ran in to several issues. required a huge amount of manual work to get something more complete. admittedly, my microscope was a piece of shit, lighting was terrible, etc etc.

I think that one was 15 images (3x5 probably)

oh ok my switch pcb stitch that was giving me serious issues was 120 that explains the difference. when I say hi-res im talking /very/ hi res

I get the feeling you must've had some calibration issues. I've done bigger stitches with hugin before. Should try another IC soon...
