Abstract When using industrial robots to process large components, accurately measuring the relative position relationship between the robot and the large components is the key to ensuring the quality of the processing. In order to improve the measurement accuracy, the position error of the laser tracker is fully considered when a single laser tracker is used for measurement in sequence with multiple stations, and the position optimization study of the laser tracker is carried out. First, the main sources of measurement errors of the laser tracker are discussed, and the principle of sequential multi-station measurement is analyzed. Then, based on the method of minimum position precision attenuation factor (PDOP), the laser tracker station is optimized, and the algorithm for solving the optimal measurement accuracy of each station position is given. Finally, the verification experiment before and after the station optimization are carried out. The results show that the measurement accuracy of the measurement system can be improved by more than 50% after the station optimization, which verifies the effectiveness of the station optimization method.
