Abstract

The invention discloses a fire point detection method of Himawari-8 remote sensing data, and belongs to the technical field of fire point detection of remote sensing data. The method comprises the following steps: preprocessing Himawari-8 satellite remote sensing data to obtain pixels and neighborhoods thereof, and making a data set; building a double-input convolutional neural network model, and inputting the radiation temperature wave band and the reflectivity wave band into the network; training a deep learning model by using the data set, iteratively updating network model parameters according to the change condition of a loss function, and converging to obtain an optimal network model; and applying the obtained model to fire point detection of data in a test set. Compared with a traditional context relative threshold algorithm, the method provided by the invention can automatically carry out fire point judgment, and can effectively improve the accuracy of fire point detection of remote sensing data.

Description

technical field

[0001] The invention relates to the technical field of remote sensing data fire point detection, in particular to a fire point detection method for remote sensing data of Himawari-8 (that is, Sunflower-8 meteorological satellite). Background technique

[0002] In recent years, fires in forests, farmland, pastures and other places on the earth have become more frequent. Recent serious fire events include the California fire in November 2018, the Amazon forest fire in Brazil in August 2019, and the Australian bushfire that lasted from 2019 to 2010. In addition, fires occur periodically in parts of Africa and Europe every year.

[0003] The occurrence of fire may be caused by the natural combustion of objects in the ecological environment, or it may be caused by human deliberation or negligence. Fires will produce a lot of smoke and harmful gases, and release a lot of carbon dioxide, seriously polluting the air environment; at the same time, it will cause dama...
