| 摘 要： | 利用LANDSAT-5的专题制图仪(TM)对中巴地球资源卫星(CBERS)-02的CCD1～4波段进行交叉定标,得到了CCD1～4波段的参考定标系数。利用该定标系数并应用气象数据和ATCOR3软件对CBERS-02的CCD数据进行大气校正;对比大气修正前后图像的清晰度和归一化的植被指数。结果表明,大气校正增强了图像的对比度,归一化植被指数(NDVI)的均值明显提高,增大了高植被覆盖区与低植被覆盖区NDVI的差别,植被信息更加突出。对于山区崎岖地表状况下,大气校正后,山体的棱角分明,轮廓清晰可见,还原了下垫面的原貌,有利于遥感信息的提取。

| Abstract: | A group of reference calibration coefficients for China-Brazil earth resource satellite(CBERS)-02's CCD data were attained by cross calibration method using LANDSAT-5's TM data.A method based on meteorological information and ATCOR3 was used in the atmospheric correction of CBERS-02's CCD four bands.The definition of image and normalized difference vegetation index(NDVI) before correction were compared with them after correction.The result shows that after atmospheric correction the image contrast is enhanc... |
