Method for identifying overhead high-voltage wire automatically from infrared image

Abstract

The invention provides a method for identifying an overhead high-voltage wire automatically from an infrared image, and aims to provide a method for extracting an overhead high-voltage wire from an infrared image reliably and accurately in real time. According to the technical scheme, the method comprises the following steps of: reading an infrared digital image which is shot from an outdoor scene into a computer program, and converting the image into a grayscale image; performing image segmentation, geometrical feature extraction, luminance feature extraction, edge contour extraction and piecewise linear feature extraction on the grayscale images by an image extraction program, and dividing the image into a target region and a background region; counting and identifying geometrical features, luminance features and piecewise linear features in the regions automatically by a feature comprehensive analysis and identification module, scanning and screening one by one, and removing suspected targets which do not have the infrared image feature of the high-voltage wire to obtain initial pixels of the image of the overhead high-voltage wire; and outputting and displaying the acquired final pixels of the image of the overhead high-voltage wire by a high-voltage wire pixel marking output module.

Description

technical field [0001] The invention relates to an intelligent target recognition technology in the field of pattern recognition, in particular to an automatic recognition method for overhead high-voltage lines with infrared images. Background technique [0002] Helicopters often need to fly close to the ground during combat or disaster relief, and overhead high-voltage power lines pose a great threat to the flight safety of helicopters. Statistical analysis shows that the vast majority of helicopter flight accidents are caused by collisions between helicopters and obstacles such as overhead high-voltage power lines, and the probability of accidents is far higher than other accidents. During the Kosovo War, the U.S. Army's "Apache" helicopter gunship was crashed and crashed to the ground because it collided with a high-altitude power line. Obviously, if the helicopter does not have the ability to identify and warn overhead high-voltage power lines, it is very dangerous. ...
