【摘要】:水下成像的好壞直接影響到水下探測的成效,但水下光場受到水中漂浮顆粒、海洋環(huán)境變化等因素的影響呈現(xiàn)出非線性。本文首先建立非均勻光場,并對其照明結構進行闡述。然后研究水下目標的襯度,并且建立了均勻光場的能見度模型,在此基礎上對接收器的視角進行改進,建立非均勻光場能見度模型,并指出其影響因素,最后通過實驗來改善影響非均勻光場能見度模型的影響因素,以此來提高水下能見度。
[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.

【正文快照】: 0引言我國海洋資源豐富,隨著經濟和科技的發(fā)展,人們對海洋的開發(fā)日益深入。水下成像是水下目標探測中的關鍵技術,但是由于水中微小顆粒的存在使得光產生了后向散射,因此影響了光場的能見度。為了提高水下成像的品質,克服散射噪聲,增加水下的能見度,本文對非均勻光場的能見度模,
