关于融合多针图确定物体3D表面绝对深度算法

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。

ON ALGORITHM OF COMBINING MULTIPLE NEEDLE MAPS FOP RECOVERING 3-D SURFACE DEPTH

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