Problems solved by technology
[0002] An important cause of error in the visual measurement technology of automobile shape is the influence of lens nonlinear distortion. If the distortion is reduced by improving the lens manufacturing and assembly accuracy, the cost of visual measurement will be greatly increased, and the impact of lens distortion cannot be completely eliminated. Impact of Visual Measurements
At present, the method of calibrating the camera to calculate the camera distortion parameters is often used. Aiming at the problems of complex calculation process of distortion correction and cumbersome operation and adjustment in the visual measurement system, a simple and low-cost car shape based on centripetal adjustment mechanism is designed. The distortion coefficient measuring instrument of the appearance measurement system is of great significance to the technological progress in the field of automobile industry inspection

Embodiment Construction
[0029] Below in conjunction with accompanying drawing, the present invention will be described in further detail:
[0030] refer to Figure 1 to Figure 10 , the distortion coefficient measuring instrument of the automobile shape measurement system based on the centripetal adjustment mechanism includes a base 1, a guide rail frame 2, a guide rail cover 3, a spring 4, a feature point slider 5, a cam 6, a motor 7, a camshaft 8, and a guide rail shaft 9 and LED light strip 10.
[0031] The base 1 is made of a rectangular steel plate with threaded holes. The base 1 is placed on the level ground. The guide rail frame 2 is mainly welded by a channel steel and two square steels. There are two threaded holes processed at one end of the channel steel. A rectangular steel plate with a through hole is welded to the bottom of each square steel, and six guide rail frames 2 are screwed and fixedly connected to the base 1 . The guide rail cover 3 is a part welded by four rectangular steel pl...
