[0003] The servo sliding module 05 is fixed on the optical platform 01, and the bracket 04 is fixed on the servo sliding module 05. The part to be calibrated 06 is fixed on the bracket 04 by four fixing screws 07. The parameters are set on the computer 03 interface to make the sliding part on the servo sliding module 05 move, and the bracket 04 and the part to be calibrated 06 move together to the set distance, thereby determining the distance between the part to be calibrated and the reference surface 02, and calibrating the part to be calibrated.

[0004] The camera installation of this calibration device for the part to be calibrated is troublesome and time-consuming. Each camera calibration requires the four screws to be loosened and fixed again.
