The invention discloses a method for forest fire recognition through employing a single medium wave infrared channel, and the method comprises the steps: discriminating cloud and water masks in received Gao Fen NO.4 satellite (abbreviated to GF-4) image data; carrying out the recognition of an absolute fire point in the GF-4 image data; carrying out the recognition of candidate fire points in the GF-4 image data; carrying out the recognition of effective background pixels of the GF-4 image data; taking pixels of the candidate fire point as the centers of windows, counting the number of the pixels of the candidate fire points and the number of the effective background pixels through employing a window splitting method, and carrying out the recognition of the fire point. The method can solve a problem of the application of GF-4 satellite data, which just has a multispectral channel and a medium wave infrared channel, in the forest fire prevention monitoring, and improves the technology of forest fire prevention monitoring.
Description
technical field [0001] The invention relates to the technical field of forest fire monitoring, in particular to a method for identifying forest fires using a single medium-wave infrared channel. Background technique [0002] At present, satellite fire monitoring methods at home and abroad mainly use the difference in brightness temperature between the mid-wave infrared channel and the thermal infrared channel of satellite remote sensing (such as AVHRR, MODIS, Fengyun, etc.) Identify burning pixels in satellite imagery. [0003] As for the image data of Gaofen-4 satellite (hereinafter referred to as GF-4) with only multi-spectral channels and medium-wave infrared channels, based on the fire point identification method combining medium-wave infrared and long-wave infrared channels in the prior art, the It cannot be applied to the automatic identification of fire spots in the satellite images, and the research on adaptive forest fire identification based on a single mid-wave i...
