Abstract

An algorithm of motion estimation using straight line correspondences and its error analysis are presented in this paper. First, a linear algorithm of motion estimation is briefly reviewed. The input data of the algorithm are point set correspondences from which line correspondences are derived. At least thirteen line correspondences are needed for the algorithm. Then, a method for error analysis for this algorithm is proposed. The error analysis is statistical and based on first order perturbation. Some simulations are carried out. The relationship between the errors in the motion estimation results and the 3D motions are also investigated.
