| 摘 要： | 针对山区地形复杂,高程变化较大的特点,利用6S辐射传输模型建立查找表,结合研究区DEM对影像进行了大气校正。试验结果表明,校正后的影像清晰度、对比度提高了,消除了大气对NDVI的负面影响。

| Abstract: | According to the results of 6S radiation transfer model sensitivity analysis,we find that when it is used to a small mountain range of remote sensing images,the influence of ground elevation to the atmospheric correction accuracy can't be ignored.Because the mountain terrain is complex and the elevation changes seriously,so we use 6S radiation transfer model to build lookup tables combining with DEM in the study area.Then to do the atmospheric correction of images.The results show that the corrected image b... |
