Abstract

The invention discloses a vehicle-mounted movable machine vision inspection system for highway pavement cracks and aims to overcome the problem that pavement crack image acquisition and pavement condition evaluation cannot be realized. The system comprises a crossbeam (1), a longitudinal beam (2), a camera (3), an adjusting rack (4) and an automobile (5). The system provided by the invention is a vehicle-mounted movable non-contact automatic detection system capable of automatic acquisition of pavement images through machine vision and evaluation of pavement damage conditions.

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 mobile road surface crack machine vision detection 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 mileage of highways has played a decisive role in promoting the economic d...
