(close) AB = ( ) A B + B AB + (AB) B The pinhole imaging model Pinhole perspective equation NOTE: z is always negative.. is the magnification. When the scene depth is small compared its distance from the Camera, m can be taken constant Weak-perspective projection Orthographic projection When the camera is at a (roughly constant) distance from the scene, take m=-1.
