Abstract Traditional coordinate measuring systems rely on the accurate kinematics of moving a sensor to the workpiece. This paper describes an instrument using a precision rotary stage to rotate a workpiece with respect to a set of three laser line sensors. The accuracy of the point cloud obtained from a single rotation of the workpiece is dependent on the rotational accuracy of the stage and knowledge of the location of the line sensors with respect to the rotary axis and each other. The calibration procedure required to locate these line sensors utilizes a precision artefact placed on the rotary stage.

摘要 传统的坐标测量系统依赖于将传感器移动到工件的精确运动学。本文介绍了一种使用精密旋转平台相对于一组三个激光线传感器旋转工件的仪器。从工件的单次旋转获得的点云的精度取决于平台的旋转精度以及线传感器相对于旋转轴和彼此的位置的知识。定位这些线传感器所需的校准程序利用放置在旋转台上的精密人工制品。
