Abstract

The invention discloses a coal field fire area determining method and device. The coal field fire area determining method includes the steps of obtaining thermal infrared image data of a target area, obtaining land surface temperature information of the target area according to the thermal infrared image data of the target area, determining the position of the burning center of coal fire of the target area according to the land surface temperature information of the target area, and determining the burning area of a current coal field fire area in the target area according to the position of the burning center of the coal fire of the target area. By means of the coal field fire area determining method and device, the effect of improving monitoring accuracy of the coal field fire area is achieved.

Description

technical field [0001] The invention relates to the field of coal fire monitoring, in particular to a method and a device for determining coalfield fire areas. Background technique [0002] Coal fire is a fire caused by coal seam combustion. The existing coal fire remote sensing monitoring technology uses a combination of remote sensing, drilling, geophysical prospecting, and field surveys to delineate the coal fire distribution area and determine the coal fire burning center. The remote sensing method uses satellite Or airborne thermal infrared, near-infrared data such as TM (Thematic Mapper, Thematic Mapper) / ETM+ (Enhanced Thematic Mapper, Enhanced Thematic Mapper) data, ASTER (satellite sensor name) data, OMIS (Practical Modular Imaging Spectrometer) Data and high spatial resolution data Quickbird, IKONOS (Ikonos satellite), etc. to extract coal fire information, satellite thermal images simply cannot allow us to identify and extract information about surface coal fires. ...
