Hence, the accuracy of laser tracking interferometer should be high enough to ensure the accuracy of system self calibration.

因此，自标定过程中需要保证激光跟踪干涉仪的测距精度。

In the laser tracking 3d coordinate measuring system, the self-calibration should be made before measurement that would take effect mostly on the result.

在激光跟踪干涉三维坐标测量系统中，系统的标定精度直接影响着系统最终测量精度。
