Problems solved by technology

Therefore, when the transmission wire dance exceeds the limit that the line can bear, it will cause serious accidents such as hardware damage, wire breakage, phase-to-phase short circuit, tower tilting or even tower collapse, causing major losses to power companies and people's production and life.

Embodiment Construction

[0021] The present invention provides a method for identifying and calculating the galloping of transmission wires based on video image processing, which will be described below in conjunction with the accompanying drawings, based on Image 6 The flow chart of the program for galloping recognition of transmission conductors is shown. The flow chart of the calculation method for galloping identification of transmission wires is as follows:

[0022] 1. Color image grayscale

[0023] figure 1 are the original image of the transmission line and the monitoring target image. Due to the large amount of color image data and the complex features of the monitoring target image, it is not conducive to quickly extracting the required feature quantities. The grayscale image is a simple image that only contains brightness information. The representation of the grayscale image usually quantizes the brightness value into 256 levels from 0 to 255, 0 is the darkest (all black), and 255 is th...

Abstract

The invention discloses a method for recognizing and calculating galloping of a transmission conductor based on video image processing, belonging to the technical field of remote digital video monitoring and image identification. The method comprises the steps of real-time transmitting a digital video signal collected by a camera to a monitoring centre through a transmission channel in the form of video stream; carrying out remote video monitoring on the field at the monitoring centre; intercepting a monitoring target image from the video stream; and calculating to obtain amplitude information of galloping through a series of image processing and identifications like image gray processing, image segmentation, transmission conductor extraction based on a chain code, Hough transformation and galloping amplitude calculation. Therefore, the galloping amplitude of the transmission conductor can be accurately, intuitively and effectively calculated; meanwhile, long-time galloping data can be saved in a database so as to provide the remote video monitoring and the image identification with original data of the galloping state of the transmission conductor, and thereby, the galloping state of the transmission conductor is convenient to analyze; and the omitted and false reports of accidents are reduced to assure the safe operation of the transmission line.

Description

technical field [0001] The invention belongs to the technical field of remote digital video monitoring and image recognition, and is mainly used for the recognition and calculation of galloping of power transmission wires, and involves image grayscale, image segmentation, extraction of power transmission wires based on chain codes, Hough transform, galloping amplitude calculation, etc. A series of image processing and recognition computing technologies can automatically recognize and calculate the galloping of transmission wires. Background technique [0002] At present, in the online monitoring system of transmission lines, the monitoring of galloping of transmission wires mainly uses a large amount of data obtained by various sensors, such as displacement sensors, acceleration sensors, wind speed sensors, etc., to comprehensively calculate the galloping size. However, this method needs to install sensors at different positions of the transmission line, especially in order ...
