This paper introduces system composition, basic measurement principle and system control principle of the in-line measurement system used in BBAC body shop flexible production line, and defines the commissioning requirements for system accuracy guarantee to realize the calibration and compensation of dimensional measurement values. The use of the visual management system IQVIS further assists the body shop to quickly and efficiently analyze the dimensional accuracy of the body in white and predict the changing trend. By setting the out-of-tolerance alarm function, the intelligent management and quality control of the three-level tolerance of the body dimension can be realized, which can significantly reduce the impact of defective body on the subsequent processes.
