摘　　要：提出了一种基于立体视觉的三维表面重建的新方法。该方法以立体视觉为基础,结合网格投影,把被动的立体视觉与主动的非结构光网格投影相结合,采用一种算法简单的由粗到精网格图像立体匹配方法,有效地解决了常用的立体视觉系统中存在的算法复杂、处理时间长、容易产生误匹配等问题。基于该方法的三维表面重建系统具有结构简单、操作方便、数据采集速度快、实时性强等优点。实验结果表明该系统能够有效地对三维表面,特别是对无明显特征的光滑自由三维曲面进行重建。A novel system for 3-D surface reconstruction based on stereo vision is proposed. By combining the passive binocular vision with active non-structure projection through a grid raster and matching from coarse to fine grid image the system effectively solves the problems such as complex algorithm, long processing time and image mismatching existed in common stereo vision system. The 3-D surface reconstruction system based on this method has the advantages of simple structure, convenient operation, fast data sampling and strong timeliness. The experimental results show that 3-D surface especially the smooth 3-D curved surface without obvious characteristics can be effectively reconstructed.
