摘　　要：针对拉弯零件的回弹检测,采用激光扫描检测设备得到拉弯零件的点云检测数据,利用Geomagic Qualify软件的比较分析功能,对拉弯件的点云数据和CAD模型进行3D、2D比较,得出了型材的整体偏差分布以及主要截面的偏差情况。并利用Geomagic Studio软件从点云数据提取拉弯零件引导线,对引导线进行曲率分析。It is introduced that the Springback test of the stretch bending formed profiles and the point cloud could be obtained by laser scanning. Considering the functions of comparison and analysis of Geomagic Qualify,the deviation of the whole parts and important sections could be inspected respectively by 3D comparison and 2D comparison acted on point cloud and CAD model. Furthermore,the guide curve of stretch bending formed profiles could be extracted from the point cloud and the analysis of the curvature for the guide curve could also be acted by the software Geomagic Studio.
