基于独立环路组合的多面体视图三维重建

提出了一种基于平面独立环路组合的多面体视图三维重建完整算法，即先把三视图中的每个视图分解成一个个独立的不可再分的平面独立环路，然后从三面视图的三个环路组中逐个取出可能的环路组合按构造实心体几何方法（CSG）构成局部实心体模型，最后将局部实心体模型组合成整体实心体模型。已按上述算法编制出了能在Auto CAD图形系统中使用的实用软件。

Reconstruction of Polyhedral Model from Orthographic Views Based on Combination of Independent Loops

An complete algorithm for reconstruction of polyhedral model from orthographic views based on combination of independent loops is proposed. In the algorithm, first each orthographic view is decomposed into planar independent loops, then the loops which comes from three loop groups of three orthographic views are made up local solid models by constructive solid geometry method (CSG) and finally the local solid models are composed into a complete solid model. The writer has worked out an active program based on the algorithm that can be run in Auto CAD system.
