Abstract

The invention discloses a body projection type commercial vehicle body length detection system based on active vision, and aims to solve the problems that image acquisition of a large-sized commercial vehicle in the overall length direction and active vision measurement cannot be realized. The system comprises a line projector seat (1), a line projector clamp (2), a camera seat (3), a camera (4), a line projector (5) and a drum-type braking bench (6). The invention provides a noncontact automatic measurement system capable of automatically acquiring body laser projected lines through active machine vision and measuring the body length.

Description

technical field

[0001] The invention relates to a detection device in the field of automobile industry, more specifically, it relates to a vehicle body projection type commercial vehicle body length detection system based on active vision. 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 de...
