    摘要:

    水体对不同波长可见光的选择性吸收和散射效应严重制约了光学成像的质量。偏振成像技术在高浊度、短距离水下环境中展现出显著优势。本研究基于红光、绿光和蓝光三种波长的激光主动偏振成像系统,对比分析了10-25 NTU典型自然水体浊度下的成像性能。实验结果表明:红光的偏振成像效果最优,绿光次之,蓝光最弱。进一步提出一种偏振图像增强算法,可显著提升三种波长激光的成像质量。在19.97 NTU浊度条件下,经本文方法增强后的潜水服布料图像熵值较传统Schechner方法提升约34.4%。研究表明,将偏振成像引入激光主动成像系统能有效改善水下成像质量,为特定波长水下成像技术的优化提供了新思路。

    Abstract:

    The selective absorption and scattering effects of water on visible light of different wavelengths severely constrain the quality of optical imaging. Polarization imaging technology demonstrates significant advantages in high-turbidity, short-range underwater environments. This study employs an active polarization imaging system utilizing three laser wavelengths—red, green, and blue—to comparatively analyze imaging performance in typical natural water with turbidity levels of 10-25 NTU. Experimental results indicate that red light achieves the optimal polarization imaging performance, followed by green light, while blue light performs the weakest. Furthermore, a polarization image enhancement algorithm is proposed, which significantly improves the imaging quality for all three laser wavelengths. Under a turbidity condition of 19.97 NTU, the entropy value of enhanced images of diving suit fabric using the proposed method shows an approximately 34.4% improvement compared to the traditional Schechner method. The research demonstrates that integrating polarization imaging into active laser imaging systems can effectively enhance underwater imaging quality, offering new insights for optimizing underwater imaging technology at specific wavelengths.
