Relative Orientation Based on Intersecting Lines

In this paper，a new relative orientation algorithm based on intersecting lines is proposed. Relative orientation parameters are obtained with the intersection equations of the extracted corresponding intersecting lines.The algorithm needs no corresponding points and can be used to solve the problem of relative orientation lacking corresponding points.Experiments with aerial images，close-range images，and oblique images show that the proposed algorithm can get robust results. Relative orientation results are more accurate and robust when combining the proposed algorithm and the traditional relative orientation method using corresponding points.
