1 is the total degree of polarization, 2 is the degree of polarization of atmospheric scattered light, and the atmospheric light intensity at infinity, generally considered a global constant. <br>In this paper, on the basis of polarization defogging, combined with the characteristics of atmospheric scattering, the weights of RGB3 channels are adjusted, and finally a more accurate defogging image is obtained. <br><br>Once 1, 2 are known, the image can be restored according to equation (1).
