CBERS-1卫星CCD相机零级图像处理研究

CCD相机是CBERS - 1卫星上的主要有效载荷之一。利用其接收的可见光和近红外谱段的图像 ,可以在国民经济的各个生产部门 ,诸如国土资源调查、农业、林业、地矿、水利、环境、生态等方面得到广泛应用。但是由于探元和光学系统成像的物理机制和各种干扰等因素影响 ,地面接收到的数据必须经过处理才能应用。文章介绍的内容就是将这种图像数据经图像预处理 ,得到零级图像 ;经过相应的辐射校正 ,得到一级图像 ;经过几何校正 ,得到二级图像产品 ,提供给其它部门加以应用

The System Study of CBERS-1 Satellite CCD Camera in Level- 0 Image Processing

The CCD camera is one of an important component in the CBERS-1 satellite If we use the images of visible-light and near-infrared band which the CCD have received, they will be used in the departments of country economy widely, such as investigation of country resource, agriculture, forest, mine, irrigation works, evaluation of environment benefit, zoology and so on Because of the lens's design and the transmission separated from odd and even list, the image data from transfer system can not be read, so we should have some corresponding processing In this paper, we will introduce an technology to design a processing system to deal with this problem First, we will do with the unread data obtain the level-0 image through the image pre-processing; Second, we can get the level-1 image through the adjust of radiation; Finally, we can attain the level-2 image through the adjust of geometry and provide to the other departments
