Findhomography lmeds
http://kyamagu.github.io/mexopencv/matlab/findHomography.html WebIf you have 3D-2D point correspondences, it's easier to just call solvePnP instead of findHomography as it will give you the pose (rotation and translation) of the object directly, instead of having to manipulate the homography further. Then you just need to get the inverse of that pose, and that's the camera pose.
