The front hood, front bumper, fender, headlight and other parts in the supply state can be batch-fast tested on the assembly inspection fixture or UCF inspection fixture, but the body-in-white is welded and assembled in the main engine factory by many purchased assemblies. At present, the conventional inspection method for the quality of the body-in-white welding assembly process is three-coordinate inspection, but three-coordinate cannot achieve rapid batch inspection, and the analysis of three-coordinate measurement data is difficult, which does not meet the needs of intuitive and rapid judgment.
