Abstract:

In order to overcome the contradiction between the super resolution reconstruction of an infrared remote sensing image and the fidelity of radiometric calibration, combined with the theory of regularized super-resolution reconstruction, a super resolution reconstruction model based on two-order total generalized variation is established. Through the analysis of the characteristics of the reconstruction model, the ADMM algorithm is introduced to solve the numerical solution. In the reconstruction process, the bilateral high-frequency filter is used to separate the high and low frequency information of the image, and after separation only the high frequency information image is dealt with. Finally, the low frequency information image and the reconstructed high frequency information image are fused to achieve super resolution. Experimental verification and quantitative analysis of the FY-4 meteorological satellite infrared image show that the influence of this method on radiometric calibration is less than that of conventional super resolution reconstruction.

Key words: radiation fidelity, super-resolution reconstruction, two order generalized variation, alternating directions method of multipliers, high frequency information image
