2D-3D homography matrix estimation
I am working with my Kinect on some 2D 3D image processing. Here is my problem: I have points in 3D (x,y,z) which lie on a plane. I also know the coordinates of the points on the RGB image (x,y). Now I want to estimate a 2D-3D homography matrix to estimate the (x1,y1,z1) coordinates to a random (x1,y1) point. I think that is possible, but I don't know where to start. Thanks! What you're looking for is a camera projection matrix , not a homography . A homography maps a plane seen from a camera to the same plane seen from another. For estimating the camera matrix, look up solutions to solving
