针对航空发动机叶片型面自动检测的难题，建立了以激光测头为核心的五轴非接触测量系统。通过合理的测量规划对叶片进行多角度、多截面自动扫描测量，得到其表面测量点及冗余点。进而将点邻域曲率特征引入到点云配准算法中，自动优化初始冗余点点集，应用ICP点云配准算法对多角度测量点进行拼接处理，最终得到叶片型面点云。

Aiming at the difficulty of the measure technique for blade of aviation engine, a 5-axis measure system was found with the hard-core of the laser point-scan sensor. This measurement could measure the blade in multiform angle and section by rational programming to get the redundancy points. The redundancy points could be auto-optimized by import the character of curvature. This system get the dimension of blade by match redundancy points with ICP (iterative closest point).
