Description

technical field

[0001] The invention relates to a detection device in the field of automobile industry, more specifically, it relates to a laser ground projection type active visual detection system for the body length of commercial vehicles. Background technique

[0002] In order to ensure the safe driving of automobiles, the measurement of automobile body length is one of the main inspection items in the field of automobile inspection. At present, the measurement of vehicle size is mainly based on manual meter measurement, which has low efficiency, poor accuracy, and high labor intensity for staff. The method of collecting vehicle images and then measuring the size of the vehicle solves the above technical bottlenecks. However, due to the complex shape and large size of the commercial vehicle, the algorithm for extracting the vehicle from the vehicle image collected by the camera is complex, the measurement accuracy is low, and it takes a long time. It cannot adapt to the...
