Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0024] refer to Figure 1 to Figure 6 , the vehicle-mounted pavement primary crack collection system based on the line structured light dynamic measurement benchmark includes a towing hook frame 1, a bracket 2, a wire casting device 3, a wire feeding device fixture 4, a camera 5 and a camera splint 6.

[0025] The traction hook frame 1 is welded by the automobile traction hook and the rectangular steel plate. The screw part of the automobile traction hook is screwed and fixedly connected with the traction hook hole of the connected car. Four circular through holes are symmetrically processed at the four corners of the rectangular steel plate of the traction hook frame 1. .

[0026] Bracket 2 is welded by rectangular steel plates, vertical steel pipes and horizontal steel pipes. The vertical steel pipes are welded vertically on the rectangular steel plates. Through ho...

Abstract

The invention discloses a linear structure light dynamic measurement benchmark-based vehicular pavement primary crack collection system, and aims at solving the problem that a pavement crack image cannot be corrected in real time when an automobile is in a motion state. The linear structure light dynamic measurement benchmark-based vehicular pavement primary crack collection system comprises a draw hook frame (1), a bracket (2), a cast instrument (3), a cast instrument clamp (4), a vidicon (5) and a vidicon clamping plate (6). The linear structure light dynamic measurement benchmark-based vehicular pavement primary crack collection system disclosed by the invention is relatively low in cost, simple in structure, high in detection accuracy, simple to operate, easy to install and reliable in performance.

Description

technical field [0001] The invention relates to a detection device in the field of traffic detection, more specifically, it relates to a vehicle-mounted pavement primary crack collection system based on a line-structured light dynamic measurement reference. Background technique [0002] Highway pavement crack detection is one of the important research contents of the traffic engineering discipline. Its research significance is to seek a road smoothness detection scheme that guarantees the optimal road surface bearing capacity, the best vehicle ride comfort, the least road traffic accidents, and the lowest fuel consumption. Highway pre-maintenance provides sufficient advanced technical guarantee and theoretical support to achieve the goal of harmony and unity between roads, people and vehicles. [0003] By the end of 2011, the mileage of highways completed and opened to traffic in China had reached 85,000 kilometers. The rapid growth of the total mileage of highways has play...
