Abstract

The invention discloses a power transmission corridor vegetation threat early warning method based on satellite remote sensing. The method comprises the steps of performing weighted gray scale transformation on the image by means of processed satellite remote sensing data; on the basis of a low-resolution multispectral image, successfully extracting a tower and a power transmission line by adopting a binarization algorithm and a Canny edge detection algorithm; based on the high-resolution fusion spectral image, establishing a spectrum library by means of a supervised classification algorithm,performing type identification on vegetation, finally, calculating a ground vegetation coverage index, reconstructing a power transmission corridor, and realizing vegetation threat early warning according to the vegetation coverage index of the ground in a vegetation and line intersection area. According to the method, the information of the power transmission corridor is successfully extracted byutilizing satellite remote sensing data with relatively high precision, so that the problems of high difficulty in manual inspection, difficulty in vegetation hazard monitoring and the like are solved, and a new method is provided for wide-area and large-range rapid inspection of power transmission line vegetation threats.

Description

technical field [0001] The invention belongs to the technical field of detection of vegetation growth in power transmission corridors, and in particular relates to a method for early warning of vegetation threats in power transmission corridors based on satellite remote sensing. Background technique [0002] As an important energy source for national life guarantee, electric power is self-evident. The construction of transmission lines is an important part of ensuring the normal supply of electricity. Due to the particularity of power transmission projects, some long-distance power transmission projects are often built in mountainous areas, which are called "transmission corridors". Mountainous areas have complex terrain and dense vegetation. As the vegetation grows, the lines may be subject to hazards such as wildfires, tree obstructions, and bird damage, which will affect power transmission. Line safety problems caused by overgrowth of vegetation have occurred from time t...
