摘要
针对叶片截面型线测量点云数据与理论点云数据的配准问题,研究了将ICP算法应用于叶型点云数据配准的方法。首先概述了叶型测量数据与理论数据的匹配问题;然后阐述了基于ICP算法的叶型点云数据配准方法,并在MATLAB平台进行了配准实现;最后给出了配准实例,并将配准结果与点云处理软件CloudCompare的匹配结果进行了对比,验证了该方法的准确性。
A method of applying ICP algorithm was researched for the data registration of blade profile point cloud.This method can be used to align the measurement point cloud data of blade profile with its nominal data.First,the matching problem was summarized between measurement data of blade profile and its nominal data.Then the data registration method of blade profile point cloud was described based on the ICP algorithm.Next,the registration process was implemented on the MATLAB platform.Finally,registration examples and comparison experiment were given with respect to the results of CloudCompare software.As a result,the accuracy of this method was proven.
