Straw incineration fire point information extraction method based on geostationary satellite remote sensing data

The invention discloses a straw incineration fire point information extraction method based on geostationary satellite remote sensing data, solves the problem that it is difficult to accurately extract an existing straw incineration fire point, and belongs to the field of agricultural environment protection. The method comprises the steps of 1, estimating the brightness temperature according to remote sensing image data; 2, extracting farmland data in a monitoring range and data of a rejected area by utilizing a remote sensing image, wherein the data of the rejected area comprises non-straw incineration fire data and residential point data; 3, taking the brightness temperature of an intermediate infrared band as a threshold judgment standard, carrying out fire point extraction on the brightness temperature estimated in the step 1, and generating fire point information data; 4, performing superposition analysis on the farmland data in the monitoring range obtained in the step 2 and thefire point information da
