Automobile body is an important carrier of all auto parts, which needs to go through stamping, welding, painting, assembly and other processes. Due to the large number of body parts and complex structure, the requirements for process technology and assembly accuracy are very high, so it is very difficult to achieve perfect size control of the body. In the process of body design and manufacturing, it is necessary to carry out high-precision dimensional measurement to avoid the impact of body size deviation on the overall appearance, performance and safety of the vehicle.
