工作空间测量定位系统(workspace Measuring and Positioning System,简称w MPS)是一种基于旋转激光扫描平面定位技术的室内大尺寸定位系统。它可实现计量精度的三维坐标测量,主要应用于制造加工及装配领域。作为一种分布式系统,工作空间测量定位系统也存在着为不同测量节点分配权重的问题。考虑到在定位过程中误差的复杂性,提出一种根据不同测量区域,利用统计数据对不同测量节点动态分配权重的分权方法。为验证此方法,设计了对比实验,实验结果表明:文中提出的加权方法可显著提高工作空间测量定位系统的测量精度。
The workspace measurement and positioning system (w MPS) is a large indoor positioning system based on the rotating laser scanning plane positioning technology. It can achieve three-dimensional measurement of measurement accuracy, mainly used in manufacturing and assembly areas. As a distributed system, there is also a problem of assigning weights to different measurement nodes in the workspace measurement and location system. Considering the complexity of the error in the positioning process, a decentralized method of dynamically assigning weights to different measurement nodes using statistical data according to different measurement areas is proposed. In order to validate this method, a comparison experiment is designed. The experimental results show that the weighting method proposed in this paper can significantly improve the measurement accuracy of the workspace-based positioning system.
