摘　　要：提出一种典型结构的建模技术与局部匹配方法。选取零件已有的典型结构,利用基于图的理论用邻接矩阵来表示典型结构的面与面之间的拓扑关系,再用基于面的几何与拓扑关系匹配方法,加速检索出含有所选典型结构的零件。A modeling technology about typical structures and a method of local matching is proposed. Selecting the existed typical structures of apart, building the topologic relations between faces based on the graph-theoretical using the relation matrix. Then quickly retrieving parts which possess the typical structures using the matching method based on the geometric and topologic relations of faces.

关 键 词：局部匹配 典型结构 拓扑关系
