A new coordinate measuring system based on spatial angle measured by rotating planar laser beams

In order to meet the need of high efficiency and high precision ultra large-scale measurement in modern manufacturing industry,a new 3D coordinate measuring system based on the principle of spatial angle measurement is proposed.The measurement principle is discussed,and the geometry model of the system is analyzed.Combining with the measurement principle and the effect of structure on the system precision structure design of key components of the system is analyzed,and the design of the whole system is finished.The experiment data shows that this system is feasible and rational.The measuring precision of the current system is close to ±0.15 mm while the distance is 6m.
