在基于结构光的在线测量系统中，采集到的点云数据反映了工件关键参数信息。结合轴类零件的特征，重点介绍了一种通过椭圆最小二乘拟合来提取轴线的方法，这也是后续三维重构与参数计算的基础。“,”In the online measurement system based on line structured light,the key parameters of work-piece are contained in point clouds collected from measuring system. According to the process characteristics of shaft free-forging,a method of extracting axis by ellipse fitting is introduced. The precision of axis is important for three-di-mensional reconstruction and key parameters calculation. The feasibility and validity is tested by experiments as well in this study.
