Abstract

This paper deals with motion estimation from image corner correspondences for two cases: the orthogonal corner and the general corner with known space angles. The contribution of the paper is in three folds: First, the three dimension structure of a corner is recovered easily from its image by introducing a new coordinate system; second, it is shown that one corner and two points correspondences over two views are sufficient to uniquely determine the motion, i.e., the rotation and translation; third, experiments using both simulated data and real images are conducted, which present good results.
