基于偏振滤波的虚拟潜望镜图像增强方法研究

Virtual periscope imaging enhancement based on polarization filter technology

为了降低海水中散射光对虚拟潜望镜成像质量的影响,利用瑞利散射理论分析了菲涅耳窗口光线分布的轴对称偏振特性,提出了一种利用放射性配置偏振镜过滤海水中散射光的方法,并对滤波效果进行了仿真分析。理论分析表明:该滤波方法对于提高海面图像具有较好的效果。

The imaging quality of virtual periscope is greatly influenced by the scattering light in the sea.To reduce the scattering light′s effect,this paper analyses the axis symmetric polarization of Fresnel window based on Rayleigh scattering theory,provides a method to eliminate the scattering light by using radial polarizer,and analyses the effect of polarization filtering by simulation method.The theoretical analysis represents that this method is feasible in sea surface imaging enhancement.
