摘要
在介绍了逆向工程的定义、逆向工程的流程及应用的基础上,综述了点云数据测量、数据预处理和模型重构的研究现状。首先介绍了点云数据测量方法的分类,然后重点分析了点云数据拓扑关系建立的方法及K近邻域索引的研究,多视点云数据拼合的点位法、固定球法、优化匹配法、特征匹配法及辅助装置法的研究,滤波去噪的方法,孔洞修复的原理,数据精简的方法,特征提取和曲面重建的基本思想和研究成果,最后展望了逆向工程技术的发展方向。
On the basis of introducing the definition, the process and application of reverse engineering, the current research status of point cloud data measurement, data pre-processing and model reconstruction are reviewed. Firstly, the classifications of point cloud data measurement methods are introduced, then focuses on the analysis of the establishment method of point cloud data topological relation and the research of K neighborhood index, point positioning method for multi-view cloud data merging, fixed ball method, optimization matching method, feature matching method and auxiliary device method research, filter denoising methods, the principle of hole repairing, the method of data simplification, the basic idea and research result of feature extraction and surface reconstruction. Finally, the development direction of reverse engineering technology is prospected.
