散乱数据的三角剖分及其在快速原型制造中的应用

Triangulation of scattered data and its application to rapid prototyping manufacturing

在考虑反求工程中通用数据分块方法的基础上 ,给出了一种快速、实用的任意多边形区域的自动三角剖分方法 .探讨了基于三角剖分的反求工程技术与快速原型技术集成的可能性 ,以及直接生成快速成型机接口文件的可行性 .

Combined with the edge\|based segmentation technique in the reverse engineering, this paper presents a rapid and practical algorithm of the triangulation for the scattered points in arbitrary polygons. In addition,the possibility of the integration of the rapid prototyping technology and the reverse engineering based on the idea of construction of triangles is discussed in detail. Also addressed in the paper is the issue of the feasibility of directly generating the interface file of rapid prototyping machine. The algorithm has been used in the reverse engineering. Some effective applications have been gained.
