Anti-break early warning scheme for power facilities based on video motion detection technology

Abstract

The invention relates to an electric power facility external damage prevention warming scheme based on the video motion detecting technology. The scheme comprises, after frame by frame reading the images of a video detected by a camera and setting a corresponding threshold value system according to the time, processing a series of the frame images of the video to extract the integral contour of an electric power facility and the virtual coil on the entire video images; then determining detecting areas; performing background extraction and update in all the detecting areas through a mixed Gaussian distribution background model; obtaining the foregrounds of the detecting areas through a background substraction method; comparing the pixel data of the foregrounds of the detecting areas with the corresponding detecting threshold values of the threshold value system; if the foreground pixel data exceed the range of the threshold values, issuing a warning signal to perform background update and foreground detection timely and accordingly ensure the real-time performance and the continuity of video detection.

Description

technical field [0001] The invention belongs to the field of digital image processing, in particular to digital image processing in the aspect of anti-breakage early warning of electric facilities. Background technique [0002] With the development of the national economy, the supply of electric power occupies an increasingly important position in the production and life of the society, and how to ensure the safe and stable operation of power facilities such as long-distance high-voltage transmission lines is an urgent problem to be solved. The rapid development of computer technology such as digital image processing has led to new ideas in the research and development of safety monitoring technology for high-voltage transmission lines. Among them, video-based motion detection technology, as a branch of computer vision applications, is a technology that combines video images and computerized pattern recognition by imitating the functions of human eyes through video cameras a...

Problems solved by technology

[0003] However, the research and development of this type of system is still far from mature, and a small number of such systems that have been reported so far have the following problems: (1) Many systems do not have intelligent detection algorithms, so they cannot automatically identify targets. Real-time monitoring and early warning can only be carried out when someone is on duty, resulting in extremely high labor costs; (2) A small number of systems have intelligent detection algorithms, but video detection is not completed by the on-site system, but is transmitted to the remote control center through wireless communication. In view of the low reliability of the wireless communication environment, it is difficult to guarantee a timely response to emergencies, and once the control center fails to operate, the entire system will be paralyzed; (3) Very few forming systems cannot solve the problem in complex scenes, occlusion scenes, and dark night scenes. In special cases such as target detection problems, it is impossible to achieve joint optimization of false detection rate and missed detection rate

These problems hinder the large-scale commercial use of such systems.
