摘要
基于光电扫描原理的分布式测量网络是一种大尺寸三维坐标测量系统,广泛应用于工业制造和装配领域。但测量网络体系庞大、测量环境复杂,增加了组网定向工作的难度,且任意节点的变动都需要重新进行组网。现有的组网定向方法过于依赖人工介入和主观估计,因此提出了一种基于自主建图、全局定位和自动导航的分布式测量网络自动组网定向方法和标定点位规划策略。实验结果表明,该组网方法在保证测量精度的前提下,提高了组网效率和自动化水平,可实现测量系统自动维护和工业现场自动化。
Abstract
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.
