Abstract

The embodiment of the invention discloses a satellite mountain fire point secondary screening method based on multi-source remote sensing data, and the method comprises the steps: obtaining fire pointdata in a preset time through a remote sensing satellite, carrying out the preprocessing of combination, intersection and the like on the original data, and obtaining the fire point data of a research region; and after the industrial fire point, the urban fire point, the secondary hazard fire point and the invalid fire point are filtered out, obtaining effective fire points of a research area; and finally, judging a fire point having influence on the power transmission line, and outputting a fire point verification result. According to the satellite mountain fire point secondary screening method, the fire point judgment rate is increased, the problem that many misjudgments exist in an existing satellite mountain fire recognition method is solved, the problem of mountain fire point secondary screening is solved in a targeted mode, the mountain fire point recognition accuracy is improved, and the mountain fire early warning accuracy of a power transmission line is improved.

Description

technical field [0001] The invention relates to the technical field of satellite remote sensing applications, in particular to a secondary screening method for satellite mountain fire points based on multi-source remote sensing data. Background technique [0002] In recent years, with global warming, extreme weather has occurred frequently, and the central and southern regions of my country are more and more prone to continuous high temperature and sunny weather during spring plowing and Qingming period. At the same time, with the implementation of national policies such as "returning farmland to forests", the vegetation in mountainous areas is becoming more and more intact. Since transmission line corridors often pass through mountainous areas and agricultural areas, the frequency of wildfires near transmission lines is increasing year by year. Wildfires on transmission lines have become a major hidden danger affecting the safe operation of smart grids. In severe cases, the...
