Abstract
The depth information is lost in the projection from a 3D object to a single 2D image and there are no geometric invariants of such a projection. However, there are invariant relations relating the projective invariants of a 3D point set and those of its 2D image under general projective projection. We present a general method to derive these relations in this paper.
