Embodiment 1

[0045] The characteristics of power towers in aerial images are as follows: (1) power towers occupy more pixels in aerial images, and the brightness value is larger; (2) power towers appear as visible axisymmetric polygons in aerial images ; (3) The connection point of the outline of the power tower is a dense area of ​​corner points.

[0046] A method for extracting pole and tower targets in the image of power transmission lines inspected by drones in this embodiment is developed in combination with the above characteristics of power poles and towers in aerial images. The process is as follows figure 1 As shown, the specific steps are:

[0047] Step 1. The power tower occupies more pixels in the aerial image, and the overall luminance value of the tower is larger than the background. Therefore, the captured image is converted from the RGB color space to the HSI chromaticity saturation luminance space, and the HSI chromaticity is extracted The I component image of the saturat...

Abstract

The invention discloses a method for extracting a tower target in an unmanned aerial vehicle routing inspection power transmission line image, and belongs to the technical field of pattern recognition and intelligent computation technologies. The method for extracting the tower target comprises the steps of converting an image acquired by aerial photographing from an RGB color space into an HSI (hue/saturation/luminance) space, carrying out binarization processing on an I component image of the HIS space after being subjected to median filtering so as to acquire a binary image of an electric power tower profile; carrying out angular point detection on the binary image of the electric power tower profile by adopting an improved Susan angular point detection method, and marking positions of all angular points in the binary image of the electric power tower profile; and detecting the mass center of an angular point sequence based on a moment invariant mass center detection algorithm, and marking the position of the electric power tower in an original image by taking the mass center as a center. Through applying the technical scheme disclosed by the invention, the electric power tower can be extracted accurately in real time, and a guarantee is provided for fault diagnosis of electric power components such as insulators, hardware fittings and the like on the tower.

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...
