Abstract

This paper deals with motion estimation from image corner correspondences in 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-dimensional structure of a corner is recovered easily from its image by introducing a new coordinate system; second, it is shown that the one corner and two points correspondences over two views are su4cient 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.
