Abstract
Coal mine fires has become a very severe geologic disaster that affects the sustainable development of China's national economy. They result in a reduction of the coal reserve, attribute to atmospheric pollution through the emission of greenhouse related gases, cause land subsidence and negatively impact human health in nearby areas. Fire source localization is an important direction in the research area of fire detection at present. For application researches of fire source localization in fire nonage, a method of fire source localization and its algorithm are presented in the paper. The method is applied to estimate the characterization of infrared image for fire source localization in condition of radiation of fire source having a character of approximate spherical wave, and its convenience of fine orientation distinguishing ability is also presented. The coherence of detection precision for fire source localization applied with the method is similarity while detected in the closed or semi-closed space. Fine feasible and compatible of this detection method is represented in the paper, and especially suited for fire source localization in the rectangle restricted space.
