Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The automatic identification of pavement disease requires accurate measurement of the degree of pavement disease. Therefore, it is necessary to find a method that can accurately determine the area of ​​pavement disease.

[0026] The method for determining the pavement disease area provided by this application can be applied to such as figure 1 in the computer equipment shown. The computer device can be a server, and its internal structure diagram can be as follows figure 1 shown. The computer device includes a processor, memory, network interface and database connected by a system bus. W...

Abstract

The invention relates to a determination method and apparatus of pavement disease areas, computer equipment and a storage medium, and belongs to the technical field of image analysis. The determination method of pavement disease areas includes the steps: according to a predetermined first binary threshold, performing binaryzation on a pavement image to obtain a first binary image; according to a plurality of second binary thresholds, performing binaryzation on the pavement image to obtain a plurality of second binary images; determining the overlapping ratio between the first binary image andthe each second binary image; and according to the second binary image corresponding to the overlapping ratio satisfying the preset conditions, determining the pavement disease area in the pavement image. The technical scheme of the determination method and apparatus of pavement disease areas can solve the technical problem that difference of the characteristics of different types of pavement diseases enables the robustness of determination of the disease area is common, and can realize that accurate contour of various types of diseases can be obtained effectively.

Description

technical field [0001] The invention relates to the technical field of image analysis, in particular to a method, a device, a computer device and a storage medium for determining road surface diseased areas. Background technique [0002] Pavement disease identification is the basis for pavement condition assessment and pavement maintenance decision-making. With the rapid progress of automatic detection technology and the development of automatic identification technology for road surface diseases, a considerable part of road surface diseases can be automatically analyzed and extracted through automatic identification technology and software. The automatic identification of pavement disease needs to accurately determine the pavement disease area. In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the types of diseases visualized in the pavement are various, and the traditional technology can...
