逆向工程及其相关技术

在工业生产中，为了设计、分析和制造等目的，经常需要按照实物建立相应的几何模型，为此逆向工程技术受到愈来愈广泛的重视。本文在介绍了逆向工程的含义及其主要应用领域后，重点介绍了逆向工程中的一些相关技术问题，包括：物体表面坐标点的采集方法，坐标点集的精简、分割、拟合处理等。对逆向工程有待进一步研究的问题亦作了简要的说明。

Raverse Engineering and Its Technology

In the areas of industry, It is frequently required to create geometric model of existing objects for design, analysis and manufacturing,so that many researcher have been devoting themselves into the research on reverse engineering.This paper mainly focuses on the review of reverse engineering. After introducing the concept and application of reverse engineering, the related technology problems, such as digitization, reduction of point data, segmentation and surface fitting, etc.,are presented. In addition, the research areas which still need further work in the reverse engineering are also described.
