摘要
水下环境中的介质和悬浮颗粒产生了光散射现象,导致水下激光图像存在严重的图像退化问题,大大降低了目标图像的信噪比。本文通过对水下连续激光成像光路图的分析,推导由于前向散射和后向散射而产生的图像退化模型。
Suspended particles in the underwater environment produce light scattering phenomenon, which leads to serious image degradation problems for underwater laser imaging, and greatly reduces the signal-to-noise ratio of the images. Based on the analysis of the light path models for both backward and forward scattering diagram for underwater continuous laser imaging, image degradation are deduced
