Abstract
水下偏振成像技术是目前水下成像研究的热点，由于自然光在水中衰减大，水下成像系统多采用主动照明方式。针对分焦平面偏振成像系统中偏振照明光源与偏振探测像元偏振方向不匹配引起采集图像偏振信息存在的偏差，进而影响目标图像增强质量的问题，提出了一种分焦平面偏振成像系统光源标定方法。阐述了偏振光源的标定原理，然后给出偏振光源标定的实施步骤，最后采用偏振去雾算法和图像质量评价方法对标定前后的水下目标图像进行了图像增强和图像质量评价。评价结果表明，标定后的增强图像质量优于未标定的增强图像质量，平均梯度最大提升了2.48倍。该标定方法简单有效，实用性强，适用于分焦平面偏振成像系统偏振光源标定。
