大气活动的干扰是遥感技术发展的最大限制之一,对星载的可见光、近红外波段的光学探测器而言,大气中云雾的干扰更是不易处理。为了促进CBERS-02星CCD传感器图像的定量化应用,在对以往有关遥感图像薄云去处方法的研究的基础上,本文提出了对含薄云的CBERS-02 CCD图像进行适当层次的小波分解,然后对分解的图像进行同态滤波,最后进行图像重构而去除薄云的方法。试验结果表明,该方法既能有效的去除薄云,又可较好的保持图像细节。

The main limit of remote sensing is atmospheric effects.The effects of atmospheric on visual bands and near infrared are more serious,and the effect of thin cloud is most hard to remove.This paper introduce a way to remove the thin cloud of CBERS- 02 CCD,first decompose the image of CCD,and then homomorphic filter the image of decomposed,last reconstruct the image of en- hanced.Experimental results show that this removal thin cloud method is effective both in reserving the detail and in removing the thin cl...
