| 摘 要： | 由于大气粒子对光的多散射作用非常显著,多散射的一般表现是在各种天气条件下光源周围的辉光现象。针对恶劣天气条件下的光源图像,采用辐射传输方程建立了点光源的多散射模型。根据所得到的点扩散函数对晴朗天气下带有光源的图像添加天气效果,并对恶劣天气条件下的光源图像进行复原,去除光源周围的辉光,从而得到清晰的光源图像。仿真结果证明了该方法的有效性. |

| Abstract: | Because of the obvious multiple scattering of the light by the particles in the atmosphere,a common manifestation of multiple scattering is the appearance of glows around light sources in various weather. This paper constructs a physics-based multiple scattering model by using Radiative Transfer Function for weather degradation light image. Then according to obtained ASPF （Atmospheric Point Spread Function） weather effect is added to light images in clear weather and light degradated images are restored. The glows are removed and the clear light images are obtained. Simulation results illustrate the efficieney of the method. |
| Keywords: | multiple scattering model Atmospheric Point Spread Function image restoring deconvolve |
