Embodiment Construction

[0014] The present invention will be further described in conjunction with the following application scenarios.

[0015] see figure 1 , a road crack detection system in this embodiment includes a connected road surface detection subsystem 1, a crack image processing subsystem 2, and a mobile terminal 3. The road surface detection subsystem 1 is used to photograph the road surface to be detected, and obtain Pavement crack image, the crack image processing subsystem 2 is used to process the pavement crack image, output the pavement crack detection result, and transmit the pavement crack detection result to the mobile terminal 3; the road surface detection subsystem 1 includes multiple For the camera that takes pictures of the road surface to be detected, each camera is set to take pictures at different shooting angles.

[0016] Preferably, multiple cameras are divided into two groups and arranged horizontally, with the left and right groups separated by the center line of the r...

Abstract

The invention provides a road crack detecting system. The road crack detecting system comprises a road surface detecting sub system, a crack image processing sub system and a mobile terminal, which are connected with each other; the road surface detecting sub system is used for shooting a road surface to be detected so as to obtain a road surface crack image; the crack image processing sub system is used for processing the road surface crack image, outputting a road surface crack detecting result and transmitting the road surface crack detecting result to the mobile terminal; and the road surface detecting sub system comprises a plurality of cameras used for shooting the road surfaces to be detected; and during shooting, each camera is provided with different shooting angles for shooting. According to the road crack detecting system, lots of human and material resources can be omitted and information of road surface cracks can be obtained through the mobile terminal in time.

Description

technical field [0001] The invention relates to the technical field of road pavement detection, in particular to a road crack detection system. Background technique [0002] Pavement is an important part of the road, and its quality affects the service level of the road. Cracks are one of the major damages to highway pavement. In the process of road maintenance and management, if the road surface cracks can be found early and maintained and repaired, a lot of manpower and material resources will be saved in road maintenance. In the past, traditional manual detection methods were used in pavement crack detection. With the development of highways and the increase of their quantity, this manual detection method can no longer meet the requirements of highway development. [0003] In related technologies, pavement crack information is obtained by identifying and processing pavement crack images. When enhancing the pavement crack image, the edge and detail information can be h...
