三坐标自动测量——角点参考测量法

CMM automatic measurement-turning point reference measurement

在白车身三坐标自动测量中,存在因车身尺寸的漂移导致角点测量发生采点错误,从而产生粗大误差的现象,该文探讨了如何通过参考测量产生的反馈,使测量程序自动纠正粗大误差的原理和验证经过。

During the automatic measurement of white body by CMM, because of the dimension of the body was instability, the wrong points were picked by CMM in corner, these lead to the big error .This thesis discusses theory and process of how to use the feedback from reference measurement, in order to correct the error of CMM automaticly.
