Algorithms for Surface Smoothing in Reverse Engineering
-
摘要: 反向工程是根据产品模型快速制造复杂产品的主要方法之一,是CAD/CAM技术的重要组成部分.曲面光顺是反向工程中的重要技术.给出了一套简单的、实用的对曲面进行光顺的算法——检查处理错误点、单步光顺、手动光顺和自动光顺,详细介绍了前3种更偏向于工程实践的算法,讨论了这组算法的关系以及它们在反向工程中的应用.Abstract: Surface smoothing is one of the important technologies of reverse engineering. This paper introduces a set of simple and useful algorithms for surface smoothing, including disposing error points, step smoothing, hand smoothing and automation smoothing, relationships among these algorithms and skills of using these algorithms in engineering are discussed in detailed. The feasibility of these algorithms are verified by their application in automobile engineering.
