Abstract :
A hybrid pyramid machine has been built for real-time computer vision applications. An algorithm for line-based motion stereo is presented. Input data is obtained from a single camera and a moving belt. A parallel and hierarchical (pyramidal) algorithm for line merging and matching is described. It is shown that the problem of matching lines among the multiple motion stereo images can be effectively carried out in a 3-D Hough space. Preliminary experimental results from the hybrid pyramid are presented. The system is capable of producing depth maps along the linear features in less than a second
