Workspace measuring and positioning system based on rotating laser planes

Abstract

This paper introduces a novle type of large-scale coordinate measurement system by the name of wMPS (workspace Measurement and Positioning System), which is based on scanning planar laser beams and multiderection positioning. wMPS provides a novel technical solution for large-scale coordinate precision measurement. System configuration of wMPS was represented and multiplane constraint mathematical model was established in global coordinate system to achieve positioning. Adjustment calibration method as the basis for measuring was described, as well as the setup process. At last, an actual measuring network using three transmitters was built up. The experiment results show that the overall accuracy of the system can be achieved within 0.1 mm at the range of 10 m and has a satisfactory stability.
