Determining 3D structure and motion of man-made objects from imagecorners

摘要

This paper deals with motion estimation from image cornercorrespondences for two cases: the orthogonal corner and the generalcorner with known space angles. The contribution of the paper isthreefold. First, the three dimensional structure of a corner isrecovered easily from its image by introducing a new coordinate system.Second, it is shown that the correspondence of one corner and two pointsover two views is sufficient to determine the motion uniquely, i.e., therotation and translation. Third, experiments conducted using bothsimulated data and real images present good results
