Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0022] refer to Figure 1 to Figure 6 , the multi-scale flexible verification targets of the vehicle-mounted pavement crack detection system with active vision include No. 1 target 1, No. 2 target 2, No. 3 target 3, No. 4 target 4 and base 5.

[0023] The base 5 is a cylindrical steel part with an arched cross section. The upper surface of the base 5 is processed with four equal-diameter threaded holes, and the lower surface of the base 5 is placed on a level ground.

[0024] The bottom of No. 1 target 1 is a threaded cylinder. A rectangular steel plate is welded on the top of the cylinder. Five parallel steel plates with decreasing heights are welded vertically above the rectangular steel plate. The distance between the parallel steel plates is 4mm. The bottom of No. 1 target 1 The processing threaded cylinder is fixedly connected with the upper surface of the base 5...

Abstract

The invention discloses a multiscale flexibility verification target of a vehicle-mounted pavement crackle detecting system based on active vision, and aims to solve the problem existing in the test of the illumination influence of the vehicle-mounted pavement crackle detecting system based on the active vision. The system comprises a No.1 target (1), a No.2 target (2), a No.3 target (3), a No.4 target (4) and a base (5), wherein the lower surface of the base (5) is put on flat ground, the No.1 target (1), the No.2 target (2), the No.3 target (3), and the No.4 target (4) are in fixed and threaded connection with four threaded holes processed in the upper surface of the base (5). The system provides the multiscale flexibility verification target of the vehicle-mounted pavement crackle detecting system based on active vision, which is small in space usage, simple in structure, high in detection precision, simple and convenient to operate, easy to mount, low in cost and reliable in performance.

Description

technical field [0001] The invention relates to an auxiliary device for a vehicle-mounted road surface crack detection system with active vision, more specifically, it is a multi-scale flexible verification target for an active vision vehicle-mounted road surface crack detection system. Background technique [0002] In order to ensure the safe driving of the car, reasonably and quickly detect the damage degree and crack expansion degree of the road surface, the crack measurement is one of the main detection items for detecting the road condition of the road surface. At present, the measurement of cracks is mainly based on manual meter measurement, which has low efficiency, low precision, poor anti-interference performance, and high labor intensity for staff. The laser plane is used to scan the crack, and the crack image is collected by the camera to measure the size and shape of the crack. It is fast, accurate and reliable, and is expected to solve the above technical bottle...
