Photoelectric scanning-based distributed metrology system is a large-size three-dimensional coordinate measuring system that is widely used in industrial manufacturing and assembly environments. However, the huge measurement network system and the complexity of the measurement environments increase the difficulty of networking orientation and changes in any node will require re-networking. The existing networking orientation method shows excessive dependence on manual operation and subjective estimation. Therefore, an automatic networking orientation method and calibration point planning strategy based on active mapping, global positioning, and automatic navigation are proposed. Experimental results show that the proposed method has improved the efficiency and automation level of networking and can realize the automatic maintenance of the measurement system and industrial automation.
