Abstract

The invention discloses a thunder fire early warning identification method based on satellite remote sensing. The method comprises the following steps: acquiring a satellite remote sensing signal; performing three-dimensional lightning data analysis based on time difference positioning; performing multi-source remote sensing data fusion analysis; constructing a forest fire monitoring and forecasting model based on deep learning; and performing satellite remote sensing thunder fire early warning and fire point identification early warning. According to the satellite remote sensing-based thunder fire early warning and identification method provided by the invention, the thunder fire early warning and identification method is established based on the satellite remote sensing data, the unmanned precise early warning and identification of the thunder fire based on the data are realized, the reliability is high, the stability is good, and the early warning and monitoring efficiency is high.

Description

technical field [0001] The invention belongs to the field of satellite remote sensing, and in particular relates to a thunder fire early warning identification method based on satellite remote sensing. Background technique [0002] With the development of economy and technology, people pay more and more attention to the natural environment. With the frequent occurrence of extreme weather, people are paying more and more attention to the fires caused by lightning. Although lightning fire is a natural phenomenon of nature, it poses a serious threat to forests and the like. Therefore, the early warning and identification of thunderstorms have become the focus of research. [0003] At present, my country's early warning and monitoring of thunder and fire are still in the stage of manual monitoring: monitoring is carried out through the inspection of forest guards and watchtowers, and at the same time combined with weather forecasts for lightning early warning. However, it is ...
