Calibration method of circumference receiver based on circumference constraint location method
In allusion to the intersection error of workspace Measurement and Positioning System (wMPS) and the occlusion problem in the complicated measurement spot, a new circumference receiver was designed based on multi-angle circumference constraint location method and the calibration method was presented. With scanning laser plane measurement principle and feature, the receiver consisted of six photoelectric receiving elements was fixed on a cyclinder. The structure and the calibration method of the circumference receiver were elaborated in detail based on two laser transmitters in this paper. The calibration method was verified with wMPS experimental platform designed by Tianjin University. The experiment results show that the measurement repeatability of the calibration is within 0.2 mm and the accuracy is within 0.3 mm. This method solves the complicate measurement system space scene occlusion and eliminates the impact of intersection error on the measurement result in principle.
