I have a problem with stereocalibrating images using opencv StereoCalibrate. Basically this is because of rather poor quality of photos I use (640x480 blurry images). However, I have got an idea, that I can put a good quality texture over the photos in some image editor (e.g. Photoshop), for it seems to me now that to determine relative camera position you just need somehow to find out where are the corresponding points are, and this approach seems to preserve this information. Of course, I will loose some information about distortion coefficients.
How do you think, is it correct way?
