Abstract(in English) | This paper addresses the factorization method to estimate the projective structure of a scene from feature(points) correspondences over images with occlusions. We propose both a column and a row space approaches to estimate the depth parameter using the subspace constraints. The projective depth parameters are estimated by maximizing projection onto the subspace based either on the Joint Projection matrix(JPM) or on the the Joint Structure matrix(JSM). We perform the maximization over significant observation and employ Tardif's Camera Basis Constraints(CBC) method for the matrix factorization, thus the missing data problem can be overcome. The depth estimation and the matrix factorization alternate until convergence is reached. Result of Experiments on both real and synthetic image sequences has confirmed the effectiveness of our proposed method. |
