It can let the dressing tools turn around, influence of running around the rotating axis on the two movingaxes wont be considered, thus the corresponding nc programming is easy.
而且它能使修整工具转动，可不考虑绕转动轴的转动对两移动轴的影响，故数控编程容易实现。

In this experiment we use a stationery system with two identical cameras with parallel axes to track a moving object in three dimensional space.
这个实验，我们用一种用平行轴固定的两台同步摄像机定位系统来跟踪一个三维空间中的移动物体。

Based on analyzing the influence of dynamic errors on measuring precision, space position of three axes, moving parameters of probe and measuring velocity also be acquired and analyzed.
