摘要:本文介绍一种LANDSATTM卫星影像校正方法,通过传感器校准、大气校正、地形校正等步骤获得反射率影像,卫星飞越时的大气参数是由当地气象记录的内插值导出,再以像幅内黑暗地物做调整,所用的大气传输模型为改进的Turner模型,可计算阳光直接辐照度、天光辐照度、路径亮度等参数,地形模型既可用来调整各参量随高程的变化,又可用以校正幅射的地形效应。
The complexity of forest canopies and the variability of atmospheric conditions necessitate the normalization or standardization of satellite imagery. Standardized reflectance images were produced by using atmospheric correction in a simplified procedure. The atmospheric parameters at overpass time were evaluated by using interpolation among local meteorological records. The path radiance derived from the visual range is adjusted by the dark pixels in the image data. The normalized reflectance images were enhanced with linear or nonlinear transformation for storage. A set of four date subscenes were used as examples to illustrate the good correspondence of reflectance results from quite different atmospheric conditions.
