Abstract
We present two linear algorithms for 3-D reconstruction: one is for finite motion; the other is for optical flow. We compare their performance by simulation and real-image experiments, using the same data. The two algorithms are both theoretically optimal, extracting maximum information from the input. We observe that the 3-D reconstruction by the finite motion algorithm is generally more accurate than by the optical flow algorithm if point correspondences are identified with optical flow.
