Abstract

The invention relates to the technical field of steppe fire monitoring, and provides a steppe fire monitoring and early warning method and device based on multi-source heterogeneous data, a computer readable storage medium and computer equipment. The method comprises the steps of acquiring an unmanned aerial vehicle multispectral image, a first satellite remote sensing image and grassland environment influence factor data; performing correction processing on the first satellite remote sensing image according to the unmanned aerial vehicle multispectral image to obtain a second satellite remote sensing image; according to the second satellite remote sensing image, constructing a combustible moisture content inversion model; according to the combustible moisture content inversion model and the grassland environment influence factor data, a grassland fire danger index model is constructed, and a grassland fire danger index grid map layer is obtained; obtaining a grassland fire danger grade zoning map according to the grassland fire danger index grid map layer; and determining a target monitoring area according to the grassland fire danger grade zoning map. By adopting the method, the fire point identification efficiency can be improved, the phenomenon of underreporting is avoided, and the accuracy of determining whether a fire occurs in the grassland is improved.

Description

technical field [0001] The present application relates to the technical field of grassland fire monitoring, in particular to a grassland fire monitoring and early warning method, device, computer-readable storage medium and computer equipment based on multi-source heterogeneous data. Background technique [0002] Grassland fires refer to disasters caused by natural or human-induced burning of combustible materials in grasslands. Grassland fires have caused huge losses to grassland resources, animal husbandry production, and the ecological environment. [0003] In order to reduce the losses caused by grassland fires to grassland resources, animal husbandry production and ecological environment, the existing fire monitoring and early warning methods mainly include artificial ground observation, satellite remote sensing monitoring and ground wireless sensor network monitoring. Among them, artificial ground monitoring mainly uses observation decks built on the ground and manual ...
