用金字塔图法匹配边界图象的三眼立体视觉方法

本文在分析了双眼立体视觉面临的本质困难之后，提出了用金字塔图法匹配特征基元的三眼立体视觉方法，这种方法由于建筑在透视投影几何原理的稳固基础上，无须任何先验限制，也不以图象相似性为基础，故可较好地解决精度与匹配难度的矛盾，且运用金字塔图法进行匹配传播使在保证精度的基础上，匹配速度大大提高，对计算机人工图象的匹配结果表明，误匹配率几乎为零，且有较高的匹配速度和精度。

TRINOCULAR STEREO VISION BY EDGE PYRAMIDAL GRAPH MATCHING

After pointing out some essential difficulties in binocular stereo vision systems, we proposedthen a trinocular stereo vision method matching the feature primitives in 3-D space by use of pyramidalgraph.This method is based on the 3-D perspective projection geometry and needs no prior constraints or im-age similarities,so it can solve better the contradiction between the accuracy and matching difflculty. And theuse of pyramidal graph can speed up the matching process also. The experimental result for artirlcial imagesshows that the ratio Of false targets is almost zero,and the matching speed and accuracy is higher.
