偏振光学复原技术是常用的水下成像复原技术,能够有效抑制后向散射,实现图像的有效复原。分析该技术,针对其受探测器视野限制,在复杂强散射水下场景获取的信息有限,导致水体后向散射相关参数估计不足的问题,设计一种基于Stokes矢量的多视角水下偏振成像算法,利用多视角成像系统扩大探测视野,获取更多的有效信息,对多视角偏振信息进行融合,优化后向散射相关参数的估计值。通过对比实验验证,结果为水下复原图像质量得到明显提升。结果表明该方法在复杂强散射水下环境中能够有效地增强图像对比度和细节。

Polarization optical restoration technology is the universal underwater image restoration technology,which can effectively suppress backscattering and achieve effective image restoration.Owing to the limitation of the detector′s field of view and the limited information obtained in the complex scattering strong underwater scene,a multi view underwater polarization imaging algorithm based on the Stokes vector is designed.Multi view imaging system is used to expand the detection field of view,obtain more helpful information and multi view polarization information Finally,the estimation of backscattering parameters is optimized.Through the comparison experiment,the results show that the quality of subsurface restoration image has been significantly improved.The results show that the method can effectively enhance the image contrast and detail in the complex scattering strong underwater environment.
