I have to images, respectively from left and right camera calibrated in stereo configuration. Images are rectified. Now I would like to fit this images together and prepare them for passive displaying (vertical lines interlacing). Has anybody some good tips what should I do now? The images differ a bit in respect of frame (shifted in vertical direction), brightness and one of them is of poorer quality than the other. Does 3D reprojection make some sense in this case? Or do I only need to find corresponding pixels in those images and fit them together?
