Then, by using the camera calibration parameters, 3D coordinates of each feature point in the machinecoordinate system were calculated.
由摄像机标定参数，进一步计算出各特征点在机器坐标系中的三维坐标；

Lastly, the mathematical models of coordinate conversion between workpiece coordinate system and machinecoordinate system are represented.
最后建立了五坐标数控机床不同结构类型的坐标转换(工件坐标系—机床坐标系)数学模型。

Based on the switch process of work piece coordinate system to machinecoordinate system, explained the function and principle of aiming at tool operation.
