Problems solved by technology

However, some physical devices still require manual operation, and the support of a large number of physical devices is required, which greatly increases the cost
In recent years, there have been more and more researches on intelligent detection methods based on image processing and machine vision, but they are only limited to the detection of cracks in road subgrades, slopes and protective structures, while little attention has been paid to other disea

Embodiment Construction

[0132] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0133] The invention provides an automatic detection method for road subgrade collapse and side slope collapse, such as figure 1 shown, including the following steps:

[0134] The first step is to read the road image. In this embodiment, the road image is obtained by using an imaging device.

[0135] The second step is to segment the collected road image, and segment the road surface image, slope image and roadbed image. Since the purpose of the invention is to identify roadbed collapse and slope collapsed accumulations, the interest ar...

Abstract

The invention provides a method and system for automatically detecting road roadbed collapse and side slope collapse. The method includes the following steps: reading a road image; dividing the road image to obtain a road face image, a side slope image and a roadbed image; conducting characteristic extraction to select GLCM-based characteristics, the Tamura-based characteristics, the statxture characteristics, the fractal characteristics, the gray level image main axis direction characteristics and the image space characteristics to serve as the characteristics of the road face image, the side slope image and the roadbed image; conducting identification and classification on the images obtained after characteristic extraction, positioning problematic areas, and calculating parameter indexes including collapse areas and collapsed body deposit capacity. By means of the method and system, the road roadbed collapse and the side slope collapse can be automatically detected according to colorful images of the road, efficiency is high, and detection is accurate.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an automatic detection method and system for road subgrade collapse and side slope collapse. Background technique [0002] With the rapid development of the road transportation industry, road transportation corridors are playing an increasingly important role in today's social economy. Transportation construction is the country's basic industry and the leading industry of economic development. Road construction has improved the structure of my country's road network, promoted inter-regional and regional economic links, effectively stimulated domestic demand, and stimulated the economic prosperity and development of areas near expressways. Regional economic development and spatial pattern evolution play an important role, and at the same time provide important convenient conditions for people's lives. [0003] The rapid development of the road transportation industry not ...
