摘要
In the online measurement system based on line structured light, the key parameters of work-piece arecontained 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 aswell in this study.
