If you look at Q matrix used in reprojectImageTo3D (we consider first image as main image here) function in openCV you can see that focal length of the first camera is used. My question is what matrix corresponds to reprojectImageTo3D in terms of Q if we do matching from right image to left (right image is main) and try to reconstruct in previous coordinate system.
