Automobile collision repair has developed from the original "smashing, pulling, and welding" to the secondary manufacturing and assembly of the car body. The repair of collision accident vehicles is no longer a simple hammering of automobile sheet metal, and the quality of the repair cannot be observed by the naked eye alone. The appearance and gaps of the vehicle. Maintenance personnel must not only understand the technical parameters and external dimensions of the car body, but also master the characteristics of the car body materials, the transmission of the characteristics of the force, the deformation trend of the car body and the stress points, as well as the production process of the car body such as welding process. On the basis of mastering this knowledge, maintenance personnel must also use advanced measuring tools, through precise three-dimensional measurement of the car body, to determine the direct and indirect damage and deformation of the car body, as well as the hidden dangers caused by the deformation of the car body, to develop a complete car body repair plan, and then cooperate with the correct maintenance process and accurate three-dimensional size data of each key point of the body to restore each key point of the car body to its original position and restore the damaged car body to the state when it left the factory.
