一种新的多面体投影线图的匹配方法

A New Approach to the Matching Perspective Views of a Polyhedron

论述了一种新的关系结构匹配方法。利用轮廓边界回路 ,简单回路 ,一阶回路 ,T型结点以及一阶树作为关系结构的基本特征。本匹配方法算法简单 ,匹配速度快 ,在多面体投影线图中部分顶点的凹凸性由于中心投影点位置不同而发生变化的情况下 。

A new approach to the relational structural matching is described.The outline circuits, simple circuits, one order circuits, T\|type node and one order trees are adopted as basic features of the relational structure. The algorithm of this matching approach is simple and the speed of matching is high. Even though the convex or concave nature of some vertexes in the perspective views of a polyhedron changes with the difference of central perspective points, this matching approach still demonstrates a strong adaptability.
