We present a geometric relationship between the image motion of pairs of points over multiple frames. This relationship is based on the parallax displacements of points with respect to an arbitrary planar surface, and does not involve epipolar geometry. A constraint is derived over two frames for any pair of points, relating their projective structure (with respect to the plane) based only on their image coordinates and their parallax displacements. Similarly, a 3 D-rigidity constraint betweendoi:10.1007/bfb0015520 fatcat:wdiwexneongvvi4zrp454smmhy
