Hi can you help find a code witch takes 2 images in input and stichs them. I found a lot when the camera does rotation (homography, etc..) but not translation. (parallax error, distortion?)

Thank you in advance.

Thank you for your reply @LBerger I've tryed to reach you since i've seen you reply for some other questions. link textlink textlink text and some others.. but like i said i've tryed homography but it only works for a camera witch does a rotation not a translation. i've tryed it but it doesn't give good results, ie we can see a gap between the 2 images. can't find a code witch works for translating camera. the camera goes on an axe and takes images of somthing on a screen witch is like 72cm far away. Merci d'avance Laurent BERGER

The size of the images are too big i think, can't attach them! How can i send them to you? @LBerger

What code did you use? (homography?) Did you see the result? Are the 2 images aligned correctly? @LBerger

You can send to me the final stitched image so i can see if it's working: nadhir.abdellatif@gmail.com
