Laser-based vehicle bottom accessory detection method

The invention discloses a laser-based vehicle bottom accessory detection method. The detection method at least comprises the following steps: S1, completing position information acquisition of a vehicle bottom accessory based on a vehicle bottom design drawing; S2, on the basis of the position information, obtained in the S1, of the vehicle bottom accessories, completing vertical arrangement of all lasers on a detection platform, the arrangement positions of the lasers corresponding to all the to-be-detected vehicle bottom accessories respectively; and S3, moving the vehicle to be detected toa preset position on the detection platform, turning on each laser, and completing vehicle bottom accessory missing or installation position deviation detection based on the laser irradiation points of each laser. The detection method is an efficient and high-precision detection means, and each vehicle can be visually and directly detected and monitored in the whole production process. The detection result is visual, the detection size precision is extremely high, and the operation method is simple and efficient.
