摘要： 该文提出的算法首先利用DPS系统获得一对表面方向图,然后,基于geodesic dome分割这对方向图并计算图中对应区域间的视差,最后,经适当融合及精确的视差匹配,确定景物物体3D表面绝对深度。这一方法对进一步研究如何确定任意3D表面深度及恢复景物结构有着十分重要的意义。

Abstract: This paper proposes an algorithm of combining multiple needle maps for recovering 3-D surface depth. The algorithm can produce first a pair of the needle maps by the dual photometric stereo system and solve disparities between the corresponding areas in the two needle maps,then it combines the disparities correctly and matches them accurately, and finally it reconstructs the 3-D depth of the object surface. This method is very useful for us to conduct research on 3-D surface depth reconstruction and to recover scene structures.

Key words: dual photometric stereo system, multiple needle maps for stereo images, absolute depth, global coordinate system
