Abstract

The invention discloses a high-speed rail tunnel leaky coaxial cable buckle detection method, and relates to the technical field of image detection methods. The detection method comprises the following steps: improving a CS-LBP algorithm, and calculating gradient direction features of a high-speed rail tunnel leaky cable buckle image sampling circular domain one by one to obtain a complete initial gradient direction feature graph; carrying out two times of continuous downsampling on the feature map, and respectively extracting continuous gradient features of the two sampled images; and the two groups of gradient features are connected in series to serve as a descriptor, and classification work of fault buckle images is completed by using an SVM (Support Vector Machine). According to the method, the feature extraction efficiency can be improved, the descriptor feature latitude can be reduced, and the contour features of the leaky coaxial cable buckle can be reflected more accurately.

Description

technical field [0001] The invention relates to the technical field of image processing methods, in particular to a method for detecting leaky cable buckles in high-speed railway tunnels. Background technique [0002] At present, railway transportation is still the main mode of transportation to solve the problem of population transfer and material transportation in our country, especially as the carrying capacity continues to increase, it is particularly important to ensure the normal operation of the railway communication system. The communication network in the mountainous tunnel section is mainly realized by covering the leaky cable, which is usually hung on the tunnel wall and fixed with a special buckle. The air pressure and energy waves generated when the high-speed train passes through the tunnel will affect the buckle, and the wet geological environment will also accelerate the loosening or even detachment of the buckle. The main detection method for leaky cable bu...
