Verification system for vehicle-mounted pavement primary crack acquisition system based on line structured light reference

Abstract

The invention discloses a verification system for a vehicle-mounted pavement primary crack acquisition system based on line structured light reference, which aims at solving the problem that verification of the vehicle-mounted pavement primary crack acquisition system based on line structured light reference cannot be realized. The system comprises a height lifting adjusting platform (1), a target plate (2) and a wedge-shaped pad (3). According to the system provided by the design, the height and the angle can be respectively adjusted by virtue of the height lifting adjusting platform (1) and the wedge-shaped pad (3), and the vehicle-mounted pavement primary crack acquisition system based on line structured light reference is further verified.

Description

technical field [0001] The invention relates to a verification device of a detection device in the field of traffic detection, more specifically, it relates to a verification system based on a line-structured light reference vehicle-mounted pavement primary crack collection system. 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 mil...
