| 摘 要： | 在0级图像中,由于成像方式、仪器本身及摄取图像时的条件等因素的影响,往往存在较严重的辐射畸变,直观表现是图像中明暗差异明显,搭接部分与其它区域的亮度不均一,造成明显的条带噪声等问题。文中介绍利用CBERS-1卫星CCD相机星载定标数据,去除这些缺陷的辐射校正方法,方法简单,便于实现,实际使用效果良好。

| Abstract: | In the level-0 image, severe radiate distortions often occur due to the influence of such factors as the imaging methods themselves, photographic instruments and photographic conditions. These distortions find expression in phenomena like obvious differences in brightness, uneven brightness between the joining part and other areas, and apparent stripes. This paper puts forward the radiation correction method for eliminating these defects by applying CBERS-1 CCD camera data. The method is very effective and the correction result is satisfactory. |
