Abstract

The invention discloses a method for jointly detecting coal fire by thermal infrared and radar remote sensing. The method comprises a step of acquiring a thermal infrared remote sensing image of a predetermined area and obtaining surface temperature information of the predetermined area by the inversion of a surface temperature, a step of acquiring a SAR image of the predetermined area and obtaining surface deformation information of the predetermined area by InSAR time series analysis, a step of designing and generating a corresponding band pass filter according to the surface deformation information of the predetermined area, and a step of performing space filtering on the surface temperature information through a band pass filter to obtain a suspected coal fire distribution position ofthe predetermined area. According to the method of the invention, the efficiency, accuracy and reliability of coal fire detection can be improved.

Description

technical field [0001] The invention relates to the technical field of exploration, in particular to a method for jointly detecting coal fires by thermal infrared and radar remote sensing. Background technique [0002] Coal fire refers to the coal buried in the ground is ignited by natural or human factors, but is not discovered and treated in time, and gradually spreads and develops to form a large-scale coal field fire. Coal fires will not only lead to a large waste of coal resources, but also produce a large amount of toxic and harmful gases, endanger mine production safety, cause air pollution, endanger the fragile ecological environment of mining areas, and even the health of residents. At the same time, fires in coalfields will erode the coal pillars of mines, destroy the stability of the geological structure of abandoned mines, cause geological disasters such as land subsidence, subsidence, and ground fissures, and threaten the safety of local infrastructure and resid...
