Computer vision-based real-time detecting and tracking method for electric power transmission circuit of aircraft

Abstract

The invention discloses a computer vision-based real-time detecting and tracking method for an electric power transmission circuit of an aircraft in a complicated natural environment background. The method comprises the steps of: firstly extracting a pixel point cloud of the electric power transmission circuit by using an anti-noise gradient image and a maximum between-cluster variance algorithm; then screening detected straight segments in a Hough space by utilizing a K-means algorithm; and tracking and detecting according to the straight segment information detected by previous frame of video image by using a Lalman filter. The method has the advantages that: the influence of illumination on the detection of the electric power transmission circuit is eliminated, the detection accuracy of the electric power transmission circuit is improved, the detection time is shortened, the workload of inspecting workers is relieved, the inspecting efficiency is improved, and the phenomenon of the missed detection of the electric power transmission circuit in the inspection process is avoided.

Description

technical field [0001] The invention relates to a method in the technical field of image processing, in particular to a method for real-time detection and tracking of aircraft power transmission lines based on computer vision. Background technique [0002] In recent years, the sustained and rapid development of my country's national economy has put forward higher and higher requirements for my country's electric power industry. Due to the vast territory of our country, the terrain of transmission line corridors is complex, there are few plains, more hills and mountainous areas, and the meteorological conditions are complex. The number of transmission lines crossing rivers is also increasing. The limitations of the traditional manual line inspection operation mode are increasingly prominent. The demand for line inspection operations is becoming more and more urgent. With the continuous development of aircraft in the low-altitude field, it has become possible for aircraft to ...
