摘要
ICP算法是三维激光扫描数据处理中点云数据配准的一种高水平的数学方法。本文全面地回顾了ICP算法的研究背景,并重点阐述了迭代最近点法ICP的计算过程及其主要的改进算法;通过建筑物三维激光扫描数据的采集,对基于ICP算法的点云数据配准过程进行了详细地分析。实验分析表明三维激光扫描数据配准后的点云数据质量较大程度上依赖于专业技术人员的数据处理经验和专业知识。
ICP algorithm is a level of art registration in data processing of 3D laser scanning point cloud.The background of ICP algorithm is reviewed in detail.The calculation course of ICP algorithm and its improved ICP algorithm are introduced in the paper.Through point cloud data acquired from the building,the course of registration based ICP algorithm is provided.The conclusion of experiment is that the quality of registration relies on the experience and knowledge of skilled worker.
