摘要
文章对我国的CBERS -1卫星遥感图像—1999年12月22日的黄河口零级数据进行了处理分析 ,并从图像空间分辨率、几何分辨率、地物识别能力等方面进行了图像质量评价。与同月份的LandsatTM图像对比 ,CBERS -1卫星图像具有更高的空间分辨率 ,更容易反映地物的细节 ,同时也指出了它的一些不足。在原有遥感地学智能图解系统的基础上 ,针对CBERS-1卫星的图像特征 ,开发了CBERS -1卫星数据预处理模块。该模块能快速处理零级图像 ,得到噪声小、清晰度高的CBERS -1卫星图像2级产品 。
In this paper, the CBERS-1 image of Yellow River Delta obtained on Dec.22, 1999 was processed and analyzed, the image quality was evaluated from some aspects, which include spatial revolution, geometrical revolution, discernment of ground objects and so on. Compared with the TM image obained at the same month, it was found that the CBERS-1image had higher spatial revolution. The paper also brings out some shortages of the CBERS-1 image. On the basis of the original remote sensing illustrated system, a CBERS-1 data pre_processing module was developed. The module can be used to quickly process the 0 class image of CBERS-1 satellite to obtain the second class products of CBERS-1 images with low noise and high definition.
