Abstract

Abstract: 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 changeable and very complex.

Key words: multi-contour reconstruction, matching shape, surface rendering

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。
