  • Abstract
    Some new results for the problem of motion estimation under orthographic projection are presented. Some basic results obtained by previous researchers are refined and more detailed and precise results are provided. It is shown that, in the two-view problem, when the rotation is around the optical axis, the motion (but not the structure) is uniquely determined. In the three-view problem, only under certain conditions are the motion and structure uniquely determined. For any motion problem, if two-view matching cannot determine the motion, only under certain conditions can three-view or multiview matching help
