摘要

用基于遥感器辐射定标参数和大气辐射传输模型计算的方法对CBERS-02卫星CCD图像进行了大气订正

较好地消除了CCD遥感图像中非目标地物的成像信息。为了消除目标邻近像元的影响

假定目标是处在某一特定反射率的大尺度参考背景下

然后再将反射率修正到实际背景中

通过这种方法获得的大气订正图像的细节部分更加清晰

对比度增强

大大改善了CCD图像的质量。

Abstract

The method

which is based on the radiometric calibration coefficient and the atmospheric radiative transfer software

is used to atmospheric correction of CBERS- 02’s CCD image.The non-object information has been removed from the CCD remote sensing image.In order to eliminate adjacent effect

it is supposed that the object is in a large scale reference background which has a certain reflectance.And then it is adapted to the actual background.By using this method

the corrected image whose detailed part is much clear than the uncorrected

has been enhanced.
