Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the embodiment of patent of the present invention is described in further detail:

[0010] The overall structural block diagram of the pavement crack detection system based on image processing. Under the illumination of the lighting source, the line array camera scans steadily along the road direction to obtain road surface images. The line frequency during acquisition reaches 10,000 lines / second. The image is continuously stored in the memory of the industrial computer, and the current mileage position is recorded at the same time. In post-processing, these pavement damages are identified by pattern recognition method and their area is calculated to obtain pavement damage information.

[0011] The high-speed video acquisition system adopts the method of compressing and storing separately. The system is between the camera and the hardware of the acquisition card and the image data. Through human-computer interaction, the d...

Abstract

The invention relates to a pavement crack disease detection system based on image processing. The device is composed of an on-line data acquisition system and an off-line data analysis system. The on-line data acquisition system is mainly composed of a pavement image acquisition system, a ground penetrating radar detection system, a laser detection system and a GPS (Global Positioning System). During detection, pavement images can be acquired through the image acquisition system, roadbed and pavement layer data is acquired through the ground penetrating radar detection system, and parameters, such as pavement deflection and flatness, are obtained through the laser detection system. The off-line data analysis system is mainly composed of a pavement image processing system, a roadbed disease analysis system, a roadbed and pavement management system and a roadbed and pavement information database. The two systems realize the detection tasks of pavement crack diseases and roadbed and pavement layer diseases; the roadbed and pavement management system realizes the summarizing and processing of the roadbed and pavement information as well as outputs roadbed and pavement condition reports and maintenance reports; and the roadbed and pavement information database serves as an organization and storage medium of the data.

Description

technical field [0001] The patent of the present invention relates to a pavement crack detection system, especially discloses a pavement crack detection system based on image processing, which is a vehicle-mounted automatic detection technology. Pavement disease and environmental health monitoring can process the collected data in real time. Background technique [0002] Highway transportation is an important infrastructure supporting national economic development and social progress, and plays an important role in the national economy and people's lives. While building, rebuilding and expanding a large number of roads, especially high-grade roads, the maintenance and management of the completed roads has also become an important issue. Highway maintenance management requires regular surveys of roadbed and pavement conditions in order to give corresponding maintenance strategies. If the roadbed and pavement diseases can be found and treated at the early stage, the maintena...
