The provided shading device for the vehicle-mounted road crack detection system based on the symmetrical four-bar mechanism is simple in structure, simple and convenient in operation, easy to install, low in cost and reliable in performance.

Description

technical field [0001] The invention relates to an auxiliary device for detection equipment in the field of traffic detection, more specifically, it is a shading device for a vehicle-mounted road surface crack detection system based on a symmetrical four-bar linkage mechanism. Background technique [0002] The quality of the road surface is closely related to driving safety. In order to ensure the safe driving of cars and reduce property losses and casualties, it is particularly important to detect road surfaces. Reasonable and fast collection of road surface images and detection of road surface cracks are one of the important contents of evaluating the damage degree of road surfaces and detecting road surfaces. . In the process of detecting the road surface, the light will have an important impact on the collection effect of the road surface image. Therefore, the use of automatic shading system to detect pavement cracks has important application value. The connecting rod...
