Abstract

The invention belongs to the field of image processing, and discloses a video monitoring method of an electric transmission line. The video monitoring method of the electric transmission line comprises the steps of greasy weather grade recognition, ice covering / snow covering recognition, conductor galloping recognition and periphery alarm. In the step of greasy weather grade recognition, vector included angle characteristics are extracted, and a support vector machine is selected and used for classification. In the step of ice covering / snow covering recognition, the ice covering / snow covering thickness is measured through image processing technologies such as image segmentation, edge detection and improved Hough conversion. In the step of conductor galloping recognition, multiple wave trough points and wave crest points in a conductor are detected, the lowest point and the highest point of conductor galloping are obtained by comparing all the wave trough points and all the wave crest points, and then amplitude and frequency of conductor galloping are computed. In the step of periphery alarm, a method of updating backgrounds automatically is adopted, influence of noise is greatly reduced in the process of judging foreign matter, and whether the foreign matter enters a monitoring area or not is judged in a percentage mode. The video monitoring method achieves video monitoring on the electric transmission line under the atrocious weather environment.

Description

technical field [0001] The invention belongs to the field of image processing and relates to a video monitoring method for power transmission lines. Through the image recognition of transmission lines, the monitoring and early warning of transmission lines in various meteorological environments can be realized. Background technique [0002] Transmission lines are the main way of long-distance transmission and distribution of electricity, and most of the lines are located in places with complex terrain and harsh natural environments. Overhead transmission line conductors and pole tower accessories have been exposed to the wild for a long time. Due to the impact of continuous mechanical tension, electrical flashover, and material aging, they will be damaged by wear and corrosion. If they are not repaired and replaced in time, serious accidents may occur. [0003] At present, the inspection method of transmission lines is mainly manual. This method not only consumes a lot of ...
