Cv2 find homography inliers
WebJan 3, 2016 · We need at least 4 corresponding points. ''' h, status = cv2.findHomography (pts_src, pts_dst) ''' The calculated homography can be used to warp the source image to destination. Size is the size (width,height) of im_dst ''' im_dst = cv2.warpPerspective (im_src, h, size) Let us look at a more complete example in both C++ and Python.
