Problems solved by technology

[0004] However, in the research process of the existing related technologies, the inventors of the present application found that due to the phenomenon of misjudgment, missed judgment and difficulty in judging in the automatic recognition of images in the relevant post-processing software at this stage, it must be assisted by manual processing. In this case, the number of images faced by the staff is huge, and a large amount of manual intervention and processing is required. That is to say, the existing road damage detection scheme has the problem of relatively low accuracy

Abstract

The invention provides a method, a device and a system for detecting the asphalt pavement condition of an expressway. The method, the device and the system are used for improving the detection precision of the asphalt pavement condition of the expressway. The method comprises the following steps that: a detection system transmits a first electromagnetic wave to a to-be-detected expressway asphalt pavement through a transmitting antenna of a geological radar, and receives a second electromagnetic wave reflected by the expressway asphalt pavement through a receiving antenna of the geological radar; the detection system generates an internal structure model on the basis of the spatial characteristics of the first electromagnetic wave and the second electromagnetic wave; the detection system determines the internal disease condition of the expressway asphalt pavement through the internal structure model; the detection system collects a surface image of the expressway asphalt pavement through a machine vision module; the detection system determines the surface disease condition of the expressway asphalt pavement through image recognition processing on the basis of the surface image; and the detection system fuses the internal disease condition and the surface disease condition to determine the expressway asphalt pavement condition.

Description

technical field [0001] The present application relates to the field of roads, in particular to a detection method, device and system for asphalt pavement conditions of expressways. Background technique [0002] As of 2020, the total mileage of my country's expressways will reach 150,000 kilometers. Most of my country's high-grade highways are asphalt pavement. Due to its good performance and easy maintenance, asphalt pavement is more and more widely used in road construction in my country. With the gradual stabilization of large-scale transportation infrastructure construction in my country, the detection and maintenance of expressways have become a huge systematic project at this stage. Various indicators of asphalt pavement (pavement damage, flatness, rutting, jumping, etc.) should be inspected once a year. The inspection and evaluation of highways is also a general task in the operation of expressways. It is the prerequisite for expressway maintenance and operation managem...
