1. after research surface reconstruction with triangular facets, contours of first layer and the last layer are triangulated with layer separation algorithm firstly . and then the least polar-angle criterion is presented for linking two convex contours, and the method is also given in which non-convex contour is transformed to a set of convex contour . with the splitting and integrating algorithm, the single-to-multi-contour reconstruction with triangular facet has been simplified to one-to-one contour
   首先采用層析式算法對(duì)起始層和結(jié)束層中的輪廓進(jìn)行三角剖分；然后采用最小極角法實(shí)現(xiàn)兩凸輪廓間的三角片重構(gòu)，并討論了非凸輪廓變換為凸輪廓的方法；最后，使用分裂與合并技術(shù)將單輪廓匹配多輪廓的三角片重構(gòu)簡(jiǎn)化為單輪廓之間的三角片重構(gòu)，最終完成整個(gè)骨骼表面的三角片重構(gòu)。
