Problems solved by technology

The detection sensitivity of existing image analysis algorithms for intelligent analysis and early warning equipment is not high, and it is difficult to accurately identify intrusion targets in the case of complex video backgrounds
It is possible that the intrusion target that breaks into the protected area cannot be detected correctly, or false alarms may be generated for natural environmental disturbances such as tree swaying, rain and snow
[0008] In the process of realizing the present invention, the inventor found that there are at least defects in the prior art such as low processing efficiency, poor timeliness and high misoperation rate

Abstract

The invention discloses a video intrusion detection method used for a power line external force damage-prevention system. The method comprises the following steps that: an Otsu's method is utilized to acquire difference image binaryzation segmentation results of current video image information; an improved SURENDRA algorithm is utilized to build a background model of a scene based on the difference image binaryzation segmentation results; and a foreground movement region is generated based on the built background model, and at the same time, the background model is updated. With the video intrusion detection method used for the power line external force damage-prevention system of the invention, defects of low processing efficiency, poor timeliness and high misoperation rate can be eliminated. The video intrusion detection method used for the power line external force damage-prevention system of the invention has the advantages of high processing efficiency, excellent timeliness and low misoperation rate.

Description

technical field [0001] The invention relates to the technical field of power detection, in particular to a video intrusion detection method used in a power line anti-external force damage system. Background technique [0002] Electric energy plays an indispensable and pivotal role in the development of the national economy. While making contributions to economic development, electric facilities are facing an increasingly prominent problem: external force damage. The occurrence of external force damage events on transmission lines has the characteristics of regularity, concealment and suddenness, which makes it difficult for the daily inspection of power supply departments to achieve ideal management results. [0003] Accidents of man-made external force damage to power lines are increasing year by year, and the forms of damage are various. The main causes of direct damage are the use of tall machinery in the line protection area, brutal construction, theft of line equipment,...
