基于相邻层轮廓线几何形状匹配的三维重建

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。

Three dimensional surfaces reconstruction based on shape of adjacent layer contours

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...
