Abstract

The invention discloses a road surface line laser rut detection and identification method and a processing system. The detection and identification method includes the steps that road surface rut laser line images are collected; characteristic extraction is carried out on the images to obtain a ridge characteristic strength graph; in the characteristic strength graph, numerical values of each row of pixel grey levels in the images present a waveform curve, one or more waveform peak points exist in each curve, the waveform peak points are candidate points of points on a laser line rut and called ridge points, and waveform ridge points of each row of the pixel grey levels are continuously looked for one by one according to peak values to determine a rut laser line. According to the method, the rut laser line can be automatically and precisely extracted in real time, the processing system has high robustness and provides precise and reliable data for calculation of subsequent road surface rut models and rut depths, and therefore measurement accuracy of the road surface rut depths is improved.

Description

technical field [0001] The invention relates to image processing, in particular to a road surface line laser rutting detection and recognition method and processing system. Background technique [0002] In recent years, with the development of my country's transportation industry, especially the rapid development of expressway construction, the mileage of expressways and the number of heavy vehicles are increasing rapidly, and the consequent deformation of road surface contours has become an increasingly prominent problem. The analysis of rutting deformation is an important part of evaluating pavement performance and the basis of scientific road maintenance. Rutting is the longitudinal strip-shaped groove formed on the track of the roadway after the road surface is repeatedly driven and rolled by automobile tires to produce flow deformation, wear, and subsidence. It is a permanent deformation of the road surface. composition. [0003] Rutting is not only one of the main dis...
