Automatic Verification System for Flatness Error of Large Flat

[摘要] This paper introduces the detection method of flatness error of flat plate, designs a large-scale flatness error automatic verification system. The structure, working principle and flatness error of least square method are described in detail, the uncertainty is analyzed. The advantages of the system are compared and analyzed by experiments, and it has a good application value.
