A method for extracting tower targets in UAV inspection transmission line images

Abstract

The invention discloses a method for extracting a tower target in an image of an unmanned aerial vehicle inspecting a transmission line, and belongs to the technical field of pattern recognition and intelligent computing. The method for extracting a tower target of the present invention includes the following steps: converting an image obtained by aerial photography from RGB color space to HSI chroma saturation brightness space, and performing a second filtering on the I component image of the HSI chroma saturation brightness space after median filtering. The binary image of the outline of the power tower is obtained by value processing; the improved Susan corner detection method is used to detect the corners of the binary image of the outline of the power tower, and the positions of all corners are marked in the binary image of the outline of the power tower; The moment-invariant centroid detection algorithm detects the centroid of the corner sequence, and uses this as the center to mark the position of the power tower in the original image. By using the technical solution of the present invention, the power tower can be accurately extracted in real time, and the fault diagnosis of the insulator, hardware and other power components on the tower can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pattern recognition and intelligent computing, and more specifically relates to a method for extracting pole and tower targets in an image of a transmission line inspected by an unmanned aerial vehicle. Background technique [0002] With the sustained and rapid development of my country's national economy and the increasing scale of urban construction, the rapid and intensive development of high-tech industries, finance, medical and health industries, and the increasing demand for electric energy, economic development not only increases the load of urban and rural power grids, but also affects The reliability and quality of power supply put forward higher requirements. Therefore, power companies need to conduct regular inspections of power line equipment, especially power lines and power towers, to ensure the stable and safe operation of the power transmission system and the normal progress of social produ...
