OpenCV: Descriptor matching with predefined constraints
up vote

I have a bunch of keypoints on leftImage and rightImage. Given that the camera can move only horizontally, how can I efficiently find the distance moved by the camera horizontally?
I believe, using homographyMatrix, __ = cv2.findHomography(pointsRight, pointsLeft, cv2.RANSAC) would be just a waste of computation, and not only that, there is no guarantee that the final homography matrix would only translate horizontally.
Or in other words, if I know the homography matrix can only be
[ 1 0 x
0 1 0
0 0 1 ]
how do I find x given keypoints and descriptors?
