Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0018] refer to Figure 1 to Figure 4 , the test system for the impact of light on the vehicle-mounted road surface crack active visual detection system includes a transparent upper cover 1 , a base 2 and an LED light 3 .

[0019] The base 2 is a hollow hexahedron part without a top surface that is welded and processed by rectangular steel plates. Threaded holes, a group of LED lamps 3 penetrate a group of circular through holes on the bottom surface of the base 2 and are fixedly connected with the base 2 by interference.

[0020] The transparent upper cover 1 is a rectangular part processed by transparent engineering plastics. The top surface of the transparent upper cover 1 is processed with crack-shaped dents. The four corners of the top surface of the transparent upper cover 1 are processed with four stepped round holes. The transparent upper cover 1 Placed on th...

Abstract

The invention discloses a vehicle-mounted pavement crack active vision detection system illumination influence test system, and aims at solving the problem of testing of the vehicle-mounted pavement crack active vision detection system illumination influence. The vehicle-mounted pavement crack active vision detection system illumination influence test system is mainly composed of a transparent upper cover (1), a base (2) and LED lamps (3). The transparent upper cover (1) on which a crack dent is processed is fixedly connected with the top end of the base (2) through threads. The illumination influence of different light intensity and different angles is simulated by the LED lamps (3) arranged at the bottom part of the base (2) so that testing of the vehicle-mounted pavement crack active vision detection system illumination influence is completed. According to the system, the vehicle-mounted pavement crack active vision detection system illumination influence test system which is small in space occupation, simple in structure, high in detection precision, easy and convenient to operate, easy to install, low in cost and reliable in performance is provided.

Description

technical field [0001] The invention relates to an auxiliary device for a vehicle-mounted road surface crack active visual detection system, more specifically, it is a test system for the illumination influence of the vehicle-mounted road surface crack active visual detection system. Background technique [0002] In order to ensure the safe driving of the car and reasonably and quickly detect whether the road surface cracks will cause safety hazards to the car, the collection of road surface images is one of the important steps to detect the road surface. In the process of detecting the road surface, the lighting conditions will have an important impact on the step of collecting road surface images. Therefore, it is very necessary to design an inspection system that can reasonably evaluate the influence of light on the vehicle-mounted active visual inspection system for pavement cracks. Contents of the invention [0003] Aiming at the problem that light affects the image ...
