This paper presents a new method for estimating motion parameters of a set of 3-D points without correspondences between points at two time instants. All point coordinates are given in projections. Three scaled orthographic projections taken before and after the motion are used to determine the scaled translation vector and to recover the 3-D scatter matrix. Once the 3-D scatter matrix is determined at two time instants, we can find the rotation matrix using eigenvector decomposition method. The proposed method requires neither correspondences in projections nor correspondences between two time instants.
