Automated recognition of fires on Earth's surface and atmospheric phenomena such as cloud, cloud veil of fog and the like, VIA SATELLITE SYSTEM

摘要

FIELD: information technologies.;SUBSTANCE: multispectral image of Earth is made at various moments of time by means of a multispectral satellite sensor, besides, each multispectral image represents a combination of single-spectral images, every of which corresponds to a certain wave length (λ), at the same time each single-spectral image consists of pixels, every of which characterises the spectral intensity of radiation (R_λ) of the appropriate Earth area; formation of a model, corresponding to spectral intensities of radiation (R_λ) of each pixel of multispectral images measured at various moments of time and physical parametres, which characterise thermodynamic agents on the Earth surface, including a possible fire on the Earth surface, in the Earth atmosphere, such as clouds, a cloudy mantle, a fog and similar; and related to relative positions of the Earth and Sun; calculations for at least one considered pixel at the specified moment of time, at least, of a physical parametre in a model that reflects a potential fire on the Earth surface, on the basis of at least the spectral intensity of radiation (R_λ,t) at the specified moment of time, earlier measured spectral intensity of radiation (R_λ,t-Δt) and the same physical parametre calculated earlier on the basis of the same model.;EFFECT: improved validity of detection.;37 cl, 2 tbl, 7 dwg
