摘　　要：高分辨率遥感成像极易受到云层遮挡等气象条件的影响。通过分析这些影响因素的特点,以暗元法为基础,提出了一种薄云的去除算法,在保持图像色调的同时,提高了图像的对比度。The high-resolution remote sensing is easily influenced by the weather such as the cloud. Through analysing the characteristics of these influencing factors, this paper introduces an algorithm to remove light cloud from remote sensing image based on dark element method. As a result, the contrast of images is enhanced, and the color is maintained.
