摘要
本文主要针对逆向工程中的关键问题，特征识别进行了比较深入的研究。由于零件的结构形状的复杂多样，从零件的切片图象识别出零件的各种几何特征，一直是逆向工程中的一个瓶颈。本文采用轮廓多边形化算法以及多边形布尔运算等方法，很好地解决了零件切片图象的特征提取问题，并讨论了实体重构的实现方法。
The solid reconstruction is always a key technology in reverse engineering and the paper deals with a algorithm of features ectraction and three- dimension reconstruction. It may automatically extract featuns from a series of care - sechons.In the algorithm, the feature extraction from the cross - sections of producte can be easily implemented by means of polygonization for each cross - section of products and the intemetion, union and difference algorithms for polygons. The solid reconstruction is simply discussed.
