摘　　要：当轮廓线比较复杂,常用的三维表面重建方法就不是很有效,有时还会出错。为此,提出一种新的基于相邻层轮廓线几何形状匹配的三维重建算法:首先提取轮廓线的关键转折点,再根据相邻层的几何形状来匹配关键点,然后连接上下匹配关键点将轮廓线分成几个独立的部分,再分别拼接各个独立部分,从而完成整个重建的轮廓拼接。实验证明,该方法对凹凸多变、复杂的封闭轮廓线有较好的效果。Conventional algorithm of three dimensional surfaces reconstruction is not very effective when the contours are complex.The paper proposed a new algorithm based on matching shape of adjacent contours:first,got the key-points of shape contours,and then matched the key-points according to shape of the neighboring layers,connected the key-points,got several independent parts,at last,reconstructed the segments respectively.The experiment proves that the algorithm is effective despite the contours are convex cha...
