I have multiple images taken simultaneously pointing at the same direction from the same starting location. However, there is still a slight offset because these cameras wer
Are the images taken standing from the same position but you're just rotated a bit so that they're not aligned correctly? If so then the images are related by a homography - i.e. a projective transformation. Given a set of correspondences between the images (you need at least 4 pairs), the standard way to find the homography is to use the DLT algorithm.
