| 摘 要： | 中巴资源卫星CBERS-02B星是我国第一颗能为众多行业提供高分辨率图像数据的卫星，广泛应用于国土资源、农业、林业、水利、环保、灾害监测、测绘、城市规划等众多领域。考虑到山区地形对高分辨影像的山区地表特征反演精度的影响，对数字高程模型(DEM)精度对地形校正的影响进行了初步分析，比较了几种常用地形校正模型：C校正、SCS+C校正、Minnaert校正和Ekstrand-r校正，并对校正结果进行了评价，结果表明以往的地形校正方法对CBERS-02B影像HR数据具有一定可行性，从而为中巴资源卫星CBERS-02B影像的地形校正提供了依据。

| Abstract: | As the first satellite,which can provide highest spatial resolution image data in China,CBERS-02 B has been widely used in territorial resources,agriculture,forestry,water conservancy,environmental protection,disaster monitoring,mapping,urban planning and so on.Mountain topography has obvious effect on the character retrival of mountain terrain surface.DEM data accuracy effect on the topographic correction was analyzed.Several correction methods,such as C correction,SCS＋C correction,Minnaert correction and Ekstrand-r correction,were compared and the correction results were evaluated.The results indicate that former correction methods are also fit for the HR data correction of CBERS-02 B image,which will provide basis for the CBERS-02 B image correction. |
