An Image-Based Detection Method for High-Speed ​​Railway Line Rod Breakage and Connecting Structure Abnormality

Abstract

The present invention relates to an image-based detection method for abnormality of pole fracture and connection structure of high-speed railway line, which adopts a multi-scale local binarization algorithm to carry out binarization processing on images taken along the high-speed railway line to be detected to highlight the main body of the line, And effectively eliminate the background interference, use a skeleton extraction algorithm to process the binary image to obtain the skeleton structure of the line, aiming at the abnormal breakage of the wire rod in the line, detect the break point by analyzing the skeleton structure of the line, find and locate possible occurrences For the location of the fracture, for the abnormality of the connection structure, the partial image of the connection body is extracted by using the line skeleton structure diagram, and the abnormality is detected and judged by using the convolutional neural network; the invention can automatically and efficiently break the wire rod of the railway line Abnormality and connection structure anomaly detection, so as to effectively improve the efficiency of transmission line safety supervision.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to an image-based method for detecting abnormality of a high-speed rail line pole fracture and connection structure. Background technique [0002] China has become the country with the fastest development of high-speed railway technology in the world. The line mileage, operating speed, and construction scale of my country's high-speed railways are all at the leading level in the world, and high-speed railways are gradually becoming a modern mode of transportation. At present, my country has developed and put into use a new type of line detection vehicle. This type of detection vehicle travels along the railway line, and the camera on the vehicle takes pictures of the line to record the real-time status of the line. Anomaly checking is performed by way of interpretation. There are many problems in manual interpretation of high-speed rail line pictures, such as long detection cycle, hi...

Problems solved by technology

Compared with the abnormality of wire pole fracture (such as disconnection of the load-bearing line) and the abnormality of the connection structure (such as deformation and cracking of the joint of the support frame), the location of the abnormality of the bird's nest does not require an accurate line structure, so the binarization adopted in the above invention Both the algorithm and the extraction method of the line structure are not suitable for the abnormal detection of the breakage of the utility pole and the connection structure
