【摘要】:水下成像的好坏直接影响到水下探测的成效,但水下光场受到水中漂浮颗粒、海洋环境变化等因素的影响呈现出非线性。本文首先建立非均匀光场,并对其照明结构进行阐述。然后研究水下目标的衬度,并且建立了均匀光场的能见度模型,在此基础上对接收器的视角进行改进,建立非均匀光场能见度模型,并指出其影响因素,最后通过实验来改善影响非均匀光场能见度模型的影响因素,以此来提高水下能见度。
[Abstract]:The quality of underwater imaging has a direct impact on the effectiveness of underwater detection, but the underwater light field is nonlinear due to the floating particles in the water and the change of marine environment. Firstly, the non-uniform light field is established in this paper. Then the contrast of underwater target is studied, and the visibility model of uniform light field is established. On the basis of this, the visual angle of receiver is improved, and the visibility model of non-uniform light field is established. The influencing factors are pointed out and the influence factors of the model are improved by experiments to improve the underwater visibility.
