| Abstract(in English) | In stereo algorithms with more than two cameras, the improvement of accuracy is often reported since they are robust against noise. However, another important aspect of the polynocular stereo, that is the ability of occlusion detection, has been paid less attention. We have intensively analyzed the occlusion in the camera matrix stereo (SEA) and have developed a simple but effective method using occlusion masks to detect the presence of occlusion and to eliminate its effect in the correspondence search. In this paper, we apply the idea to the occlusion in matching windows, and derive several occlusion masks to reduce the effect of occlusion in the matching window on an occluding boundary. It enables to obtain a dense and accurate depth map even at the occluding boundaries of objects. Experiments using typical indoor scenes showed quite good performance. |
