Abstract

A method for detecting 3-D information of rut on pavement includes forming structure light strip of structure light laser to be an image on surface array CCD after said structure light strip is modulated by 3-D information of pavement in order to obtain pavement information for making calculation through relation matrix, filtering disease influence off, calculating parameter by utilizing virtual straight scale, storing data then analyzing and displaying data. The detection device used for realizing said method is also disclosed.

Description

technical field

[0001] The invention relates to a rut detection device and a detection method. Background technique

[0002] The pavement is an important part of the road. With the increase of the mileage of the road and the number of heavy vehicles, the ruts formed by the wheel tracks on the road become one of the main factors affecting the performance of the road. The "groove effect" produced by rutting deformation causes the car body to tilt and bump, which accelerates the damage of the vehicle. Water accumulated in ruts after rain seriously affects the maneuverability and stability of the vehicle, and may even cause traffic accidents. Therefore, how to accurately and efficiently detect and evaluate the rutting index has always been a problem of great concern to the highway management department.

[0003] The technology of automatic detection of road ruts has made great progress in the world, and many products have come out. Companies such as ICC in the United States, ...
