摘　　要：现有三维扫描系统在进行薄壁类零件测量时,获取点云数据存在一定难度。以发动机叶片为例,利用拍照式三维扫描系统获取其点云数据,借助Stereo-3D及Geomagic Studio两款软件对点云进行处理,获得了反映叶片真实几何形态的曲面结构。实验结果表明,测量方法有效,可为其他薄壁类零件的数据测量提供参考。It is difficult to acquire point clouds for thin-walled parts by 3D Scanning system. In this paper, engine blade is taken as an example and camera type 3D scanning system is used to acquire the point clouds of part. The point clouds are dealt with by Stereo- 3D and Geomagic Studio to obtain surface reflecting the real geometry. The experiment result expresses this method is effective, and can gives a reference to the measurement of thin-walled parts.
