Given K, an intrinsic camera matrix, a reference image from a camera 1 which pose is known and an image from a camera 2 which pose is unknown, is there a way to compute the pose of camera 2 using the homography matrix found between the two images from matched key-points if I know their 3D coordinates? Or, if not, from anyone of the fundamental or essential matrices?
Could it perform better or faster thant SolvePnP?
