摘要
提出了一种大型锻件外形尺寸的在线测量新方法。首先通过激光扫描仪扫描锻件表面的信息，将获得的扫描仪到锻件表面的距离信息转化为坐标信息，然后进行点云拼接、数据精简和曲面重构处理，最后导入SolidWorks软件中构建锻件的三维模型，从中提取截面，给出锻件的尺寸信息，实现大型锻件外形尺寸的在线测量。
In order to on-line measurement the contour dimension of the large forging, a new measuring method is proposed. First, the distance between the scanner and the surface of the forging is gained through scanning the surface information of the forging by the laser scanner. Then the distance information is transformed into coordinate datum, which is processed using point cloud registration, data simplification and surface reconstruction. Finally the three-dimensional model is built through the processed datum importing into SolidWorks software. The size of forgings information can be got by extracting the cross section, the online measurement is achieved.
