摘要提出了一种新的大型筒节热态锻件外径在线测量方法。该方法首先通过二维激光扫描仪扫描锻件表面的信息,将扫描仪到锻件表面的距离信息转化为坐标信息,然后进行数据拼接和曲线重构,显示锻件外形轮廓曲线,测量其尺寸信息,实现了大型筒节热态锻件外径的在线测量,并利用Matlab进行仿真,验证了该方法的可行性。

Abstract：In order to on-line measure the outer diameter of large cylindrical shell section forgings,a new measurement method is proposed.First,the distance between the scanner and the surface of forging is got through scanning the surface of forging by the laser scanner.Then the distance information is transformed into coordinate information,which is processed by using data registration and curve reconstruction.Finally the contour curve of forgings is showed,thereby the size of forgings is measured.The online measurement of large cylindrical shell section forgings is achieved.This method is verified feasibility by the Matlab simulation.
