Abstract

The invention relates to an aero-optical thermal radiation effect correction method, device, equipment and storage medium. The method includes: acquiring aero-optical thermal radiation degradation images, filtering the degraded images to obtain the filtered images; performing down-sampling processing on the filtered images And generate discrete points; use the moving least squares-based surface fitting method to fit the discrete points to the initial bias field surface; input the initial bias field surface into the pre-established degradation model, and use the alternate iterative minimum method to output to meet the preset Corrected image and bias field for iterative conditions. The corrected image output in the present invention is clearer, and the correction effect is improved.

Description

technical field [0001] The present invention relates to the technical field of image correction, in particular to a method, device, equipment and storage medium for correcting aero-optical thermal radiation effects. Background technique [0002] When an aircraft carrying an optical imaging system flies at high speed in the atmosphere, there will be a violent interaction between its optical hood and the atmosphere, and a severe aero-optical thermal radiation effect will be produced at the optical side windows of the aircraft. The image produced by the optical imaging system under the effect of aero-optical thermal radiation is very blurred. The heat generated by the air compression causes the electronic response characteristics of the imaging focal plane to change, resulting in nonlinear saturation of the image and serious distortion. [0003] Aero-optics thermal radiation effect correction method is an important link in the study of aero-optics thermal radiation effect corre...
