摘要
提出了一个基于轮廓线骨架点的三角片曲面重构的算法 .首先对散乱骨架点进行拓扑连接 ,得到一个由骨架点构成的多边形 ,然后分析骨架多边形得到所需的特征骨架点 ,进而得到断层间轮廓线的相似特征部分 ,把断层间轮廓线分割为相对应的简单曲线段 ,最后 ,重构的曲面由这些分段重构的子曲面拼接而成 .
An approach is proposed for surface reconstruction from contours based on the analysis of skeleton points. The scattered skeletal points are connected into a polygon, and then skeletal points with specific features are chosen. An optimal match between featured skeletal points is calculated, thus the contours are divided into several matched segments. Finally, the surface is composed of the pieces of sub surface reconstructed from these matched contour segments.
