Abstract

The invention discloses a thermal infrared information denoising method in the coal petrography fracture development process, and belongs to a thermal infrared information denoising method. According to the method, denoising is performed on the loading coal petrography surface infrared radiation average temperature by utilizing the reference coal petrography surface infrared radiation average temperature, and then loading coal petrography surface infrared radiation average temperature change characteristics in the uniaxial loading process is obtained. According to the thermal infrared information denoising method in the coal petrography fracture development process, the problem that noise influences the coal petrography surface infrared radiation average temperature is thoroughly solved, the accuracy, the scientificity and the effectiveness of Infrared radiation average temperature data are improved, therefore, the denoised loading coal petrography surface infrared radiation average temperature change characteristics are obvious and have the inducible property, and the problem that the noise influences the coal petrography surface infrared radiation average temperature can be solved.

Description

technical field [0001] The invention relates to a method for denoising thermal infrared information, in particular to a method for denoising thermal infrared information during the development of coal and rock fissures. Background technique [0002] Infrared detection technology has been widely used in the study of the change law of coal rock fracture and instability catastrophe, so as to carry out effective monitoring and early warning of coal rock catastrophe. Some scholars believe that the average temperature of infrared radiation, as a quantitative index for studying the characteristics of infrared radiation during the loading process of coal and rock, can effectively reflect the precursor of coal rock rupture or instability. However, the dispersion of the average temperature of infrared radiation obtained by the experiment is very large, which leads to conflicting conclusions of related research. The reason can be attributed to two aspects. One is that when the tempera...
