A New Method for Epipolar Line Rectification

摘要

An improved algorithm of epipolar line rectification for stereo pairs, which combines Seitz Method with Francesco Method, is proposed. Firstly, the fundamental matrix is calculated using the Improved Eight-point Algorithm (or other improved methods such as weighted normalization algorithm) and then as an input for Seitz Method to get the projective transformation matrices. Finally, these matrices are used to initialize the Francesco Method for optimization, avoiding in this way local minima as well as the dependence on the precision of the fundamental matrix. Experimental results show that the presented method works more accurately with low image distortion in contrast to Francesco Method and Mallon Method.
