摘要
针对水下成像环境中的后向散射问题,开展了推扫式计算鬼成像方法的研究。介绍推扫式计算鬼成像模式,利用行间相关性研究了多行联合压缩感知模型,基于迭代收缩阈值算法提出了模型的求解方法。搭建了水下计算鬼成像实验装置,并在两种不同浑浊度情况下通过实验对比了推扫式计算鬼成像和传统面阵式计算鬼成像的效果,实验结果表明,推扫式计算鬼成像能够有效地降低后向散射的影响。
Abstract
To address the problem of backscattering in underwater optical imaging, a method of push-broom underwater ghost imaging computation is studied. A push-broom computation mode for ghost imaging is introduced. Multiple detection lines are combined to form a joint compressive sensing model by exploiting the inter-line correlation. Iterative shrinkage thresholding method is used to solve the model. An experiment setup of underwater ghost imaging computation is established. The proposed method is experimentally compared with traditional plane-array ghost imaging computation methods under different turbidities. Experimental results show that the proposed scheme can reduce the backscattering effectively.
