Abstract

The additive constant C and multiplication constant R are two of the most important parameters for the corrections that are made to the measurements of electronic range-finder. The two parameters have direct influence on the correctness of measurements, and therefore are requisite for electronic range-finder calibration. In the paper firstly the operations of invar ruler contrast method as well as the determination of additive constant using simple analytical method were presented. Then based on the additive constant and the characteristics of the multiplication constant, the Unequal Weight Separation Method (UWSM) for separative calibration of the additive constant and the multiplication constant was put forward. The accuracy of UWSM was also analyzed, which was verified by processing data from multiple range-finders. Analysis showed that UWSM is easy to implement, reliable, and causes low intensity of workload, which is favorable to objectively assess the performance of high-precision of electronic range-finders.
