摘要：

In this short paper, we present some new results for the problem of motion estimation under orthographic projection. We refine some basic results obtained by previous researchers and provide more detailed and precise results. We show that, in the two-view problem, when the rotation is around the optical axis, the motion (but not the structure) is uniquely determined. We show that, in the three-view problem, only under certain conditions are the motion and structure uniquely determined. We show that, for any motion problem, if two-view matching cannot determine the motion, only under certain conditions can three- or multiview matching help.
