Hi, I'm working on a project about 3d reconstruction. Now, I have camera intrinsics such as fx fy cx cy image_height image_width but I can't find other infos. Is that translation means position of camera? Since I only have 1 camera so I can't provide 9 number for rotation. Can you point it out for me please? or some resources to research will be good. Thank you very much! Have a good day ^^

Hi, I think you can retrieve the rotation and translation matrices by decomposing the homography matrix (you can read about how to compute homography matrix for agiven image pair). I am not a professional but maybe that could help. Thanks.
