Abstract

The invention provides a broken strand detecting method and system for a transmission conductor. The broken strand detecting method comprises the steps of collecting to-be-detected images shot by a video collecting device; detecting the to-be-detected images by means of a line segment detection algorithm, generating a backup segment gather image; screening the backup segment gather images based onthe preset line length threshold value and pixel average gray value, generating lead segment gather images; conducting binarization on the lead segment gather images, generating binarized images; detecting the binarized images by means of the preset lead broken strand outline module, and determining the position of the lead broken strand in the binarized images. The invention is advantageous in that the time consumed for detecting the lead broken strand can be shortened, and the detection is easy to realize; the demand for practical engineering application is met, and the accuracy and stability of detecting the lead broken strand can be increased; the real-time detection function of the broken strand in the line-cruising monitoring can be realized.

Description

technical field [0001] The invention relates to the field of detection of power transmission wires, in particular to a method and system for detecting broken strands of power transmission wires. Background technique [0002] In the intelligent line inspection system, the video monitoring system can be used to perceive the transmission line and collect relevant line information and data. With the development of aircraft technology and electric power industry, more and more image data are collected by various line-following aircraft. However, with the rapid increase of data and tasks, traditional manual monitoring has been far from meeting the needs of line patrol monitoring tasks. Therefore, realizing the intelligent automatic monitoring function that can replace the human eye and applying it to the actual line inspection system has become a joint research goal in the fields of video monitoring and intelligent power line inspection. [0003] As an important detection conten...
