摘要

分析水中粒子对光的吸收及后向散射造成的图像退化的物理模型,提出一种基于非偏振光照明的水下偏振成像目标增强技术。该技术的优势在于非偏振光照明确保了目标反射光与杂散光始终存在偏振态差异;采用偏振角特征参量确保了杂散光光强估算的精确性。与基于线偏振光照明的水下偏振成像技术相比,其适用范围更广,图像恢复精度更高。实验结果表明,该方法能够提高水下图像的能见度与对比度,对比度至少提升100%,适用于不同材质目标、不同成像距离以及不同杂质、不同浑浊程度的水体环境,在水下成像领域具有潜在应用价值。

Abstract

The underwater polarimetric imaging target enhancement technique based on unpolarized illumination is proposed based on the physical model of image degradation caused by light absorption and backscattering by particles in water. The advantage of this technology is that the unpolarized light ensures that there is always a difference in polarization between the target reflected light and stray light. And, the characteristic parameters of angle of polarization is used to ensures the accuracy of estimation of stray light intensity. Compared with the current underwater polarimetric imaging techniques based on polarized illumination, the proposed method has wide application range and high image recovery accuracy. Experimental results show that the proposed method can effectively improve the visibility and contrast of underwater images, and the contrast is increased by at least 100%. It is suitable for water bodies with different material targets, different imaging distances, and different impurities and turbidity levels. It has potential application in the underwater imaging field.
