摘　　要：针对海上光电侦察易受雾气影响造成对比度降低等问题,提出一种基于海天背景下的单幅图像快速去雾方法。方法首先通过对图像拉伸,提升目标在暗通道和亮通道中的对比度;然后依靠亮通道进行海天线检测,区分海面和天空背景;最后使用海面暗通道物理退化模型,对图像进行复原。实验结果表明,该方法简单有效,能够满足海天背景下彩色图像去雾恢复的需要。In order to solve the problem of the contrast reduction in marine electro-optical reconnaissance caused by fog, a fast dehazing method for single image in sea-sky background is proposed. First, the contrast of target in the dark channel and bright channel is enhanced by stretching the image. Then, the sea-sky-line is detected in the bright channel to distinguish the background of sea and sky. Finally, the image is restored by using the physical degradation model of dark channel of sea background. The experimental results show that the method is simple and effective, and can satisfy the need of color image restoration in the sea -sky background.
