摘　　要：搭建一种水下目标偏振光学成像探测水槽实验平台,研究斯托克斯矢量参数图像成像效果。根据图像信息指标探讨两种成像观测角度偏振图像采集方案以及最佳水下目标物距离,并分析在水体环境中多种目标材质以及不同浑浊度下目标物偏振特性信息变化。实验结果表明,采用0°、60°、120°成像采集方案,在相对较远距离以及较为浑浊的水体环境中,获取的不同材质的目标物其偏振图像仍满足目标物信息需求。由此可见,通过水下偏振光学成像获取到的图像能够较为理想地反映水下目标物的边缘细节、纹理轮廓等重要信息。An underwater target polarized optical imaging detection tank experiment platform is built,focusing on the imaging effect of Stokes vector parameters.According to the image information indexes,two imaging observation angle polarization image acquisition schemes and the best underwater target distance are discussed,and the differences in the polarization characteristics of the target object under different turbidity and multiple target materials in the water environment are analyzed.Experimental results show that using 0°,60°,and 120°imaging acquisition schemes,in a relatively long distance and in a turbid water environment,the polarized images of targets of different materials obtained can still meet the information requirements of the target.It can be seen that the images obtained through underwater polarized optical imaging can ideally reflect important information such as the edge details and texture contours of underwater targets.
