| 摘 要： | 基于辐射传输理论的大气校正模型,具有明确的物理意义,易于操作,应用广泛。该文首先对Landsat-5 TM图像大气校正参数的确定进行了详尽分析并采用6S模型对图像进行了大气校正,然后从光谱响应曲线、归一化植被指数(NDVI)等方面,探讨了大气校正对TM图像地物光谱响应特征的影响。研究表明,TM图像经大气校正后,地物在可见光,近红外和短波红外波段反射率明显减小;大气校正后的NDVI增幅明显;采用的参数确定方法可为类似研究提供参考与借鉴。

| Abstract: | Based on the radiative transfer model,atmospheric correction model has specific physical meaning,and it can be applied widely and easily.In this study,firstly the parameter determination on Landsat-5 TM image is analyzed carefully,and the atmospheric correction of the image is carried out with 6S model.Then,influence of atmospheric correction on typical object spectral response characteristics of TM image is discussed on the spectral response curves,the normalized difference vegetation index(NDVI) and visib... |
