Problems solved by technology

Use Canny operator edge detection, Hough transform to extract straight lines, and then combine straight line segments. This method has poor detection effect in complex backgrounds, and it is easy to extract a large number of miscellaneous line segments, which will affect subsequent straight line segment grouping and merging.

Embodiment Construction

[0022] The purpose of the present invention will be further described in detail through specific examples below, and the examples cannot be repeated here one by one, but the implementation of the present invention is not therefore limited to the following examples.

[0023] The overall process of the present invention is as figure 1 As shown, a power line detection method based on image processing in a complex background, specifically includes the following steps:

[0024] Step 1: Obtain the power line image through the aerial photography of the video camera or camera carried on the UAV, such as figure 2 shown.

[0025] Step 2: Use the Canny operator to detect the edge of the power line image, specifically: (1) Use the Gaussian template to smooth the image to suppress the noise of the image; (2) Use the Sobel operator to calculate the gradient magnitude and direction; (3) Exclude non-edge pixels by non-maximum suppression; (4) Obtain a binary image E containing edge informa...

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...
