Pollution gas FTIR passive telemetering scanning imaging high-resolution reconstruction method

Abstract

The invention relates to a pollution gas FTIR passive telemetering scanning imaging high-resolution reconstruction method. The method is characterized by comprising the following steps: step A, carrying out up-sampling processing on a low-resolution image of the cloud cluster column concentration of a polluted gas; step B, performing blind deconvolution processing on a sampling processing result in the step A by adopting a total variation blind deconvolution alternating minimization algorithm; step C, performing piecewise linear enhancement on the result of the step B by monitoring upper and lower limit parameters corresponding to different toxic and harmful gases; and step D, mapping the result of the step C through an HSI color space and superposing the result to a corresponding area of a background visible light image, thereby providing a high-resolution visual image for analyzing the diffusion situation of the polluted gas and positioning a leakage source.

Description

technical field [0001] The invention relates to the field of atmospheric environment monitoring, in particular to a method for high-resolution reconstruction of polluted gas FTIR passive telemetry scanning imaging. Background technique [0002] With the rapid development of society, sudden gas leakage accidents occur frequently, which poses a major hazard to the ecological environment and human safety. To prevent such accidents, normalized monitoring and early warning are one of the effective means. The Fourier transform infrared (FTIR) spectroscopy technology has the characteristics of non-contact, high response speed, and high resolution. The FTIR passive telemetry technology is combined with the scanning system to scan the area where leakage may occur, and the measured infrared spectrum The gas column concentration value is quantitatively obtained through the spectral data processing algorithm, and then the array is combined to form a low-resolution image of the gas colum...
