Power transmission line detection method under complex background based on image processing

Abstract

The invention discloses a power transmission line detection method under a complex background based on image processing. The method comprises the following steps of 1, obtaining a power transmission line image through aerial photography of a camera or a camera carried on an unmanned aerial vehicle; step 2, carrying out edge detection on the power transmission line image by adopting a Canny operator; step 3, removing small connected regions by adopting a region growing method; 4, carrying out linear detection by adopting probability Hough transform; and 5, screening the straight line segments,and removing pseudo straight line segments. The method is high in anti-interference capability, good in stability, good in detection effect and high in robustness, and real power transmission line information can be detected under a complex background.

Description

Technical field: [0001] The invention relates to the field of digital image processing, in particular to an image processing-based transmission line detection method under complex background. Background technique: [0002] Driven by the growing demand for electricity, my country's investment in power grid construction is increasing, the voltage level of transmission lines is also increasing, and the power transmission network will become more dense. Manual inspection is the most traditional inspection method, and it is also the inspection method most used by power companies at present. Inspection personnel mainly use telescopes or infrared detection equipment to conduct non-contact inspections on power lines and towers in the power line corridor. This inspection method is inefficient, long in cycle, high in risk, high in cost, subject to geographic constraints, and prone to missed or false detections. [0003] In recent years, with the implementation of policies such as the...
