Aerodynamic optical effect correction method and device

The invention relates to an aerodynamic optical effect correction method. The method comprises the following steps: acquiring a thermal radiation degradation image; performing filtering processing according to the thermal radiation degradation image, and determining a thermal radiation estimation image; performing Bessel curved surface fitting according to the thermal radiation degradation image and the thermal radiation estimation image, determining a potential clear image, and judging whether the potential clear image meets a preset condition or not; if the preset condition is not met, updating the thermal radiation degradation image and the thermal radiation estimation image, and carrying out iteration; and if the preset condition is met, outputting the potential clear image. The method is easy and efficient to implement, image correction can be carried out on the aero-optical effect degradation image, the thermal radiation effect of the image can be effectively removed by executing the method, and the ima
