A triple-laser trackers automatic measurement system for large-scale parts assembly

To address the problems of low efficiency, high cost and low automatic level existing in traditional laser tracking measurement systems, a triple-laser trackers measurement system for large-scale parts assembly is proposed. The system is composed of three laser trackers, and can fulfill automatic measurement throughout whole assembly process. Multiple extended datum marks are generated to increase assembly precision, whose 3D coordinates are calculated by known distances. Mathematical model is established, and simulation is accomplished. The simulation results show that the proposed system features relative high precision, automatic measurement and wide application.
