Projection matrix + world plane ~> Homography from image plane to world plane
- by B3ret
I think I have my wires crossed on this, it should be quite easy.
I have a projection matrix from world coordinates to image coordinates (4D homogeneous to 3D homgeneous), and therefore I also have the inverse projection matrix from image coordinates to world "rays".
I want to project points of the image back onto a plane within the world (which…
