介绍了ATCOR3的算法,应用ATCOR3对安徽铜陵及黄山地区两景TM图像进行了大气校正,并用目视比较与提取NDVI分析的 方法,比较了校正的效果。研究结果表明,ATCOR3校正后,有效地去除了薄雾对图像的影响；同时比较了ATCOR3和ATCOR2 对同地区的校正效果,发现对于山区崎岖地表状况下,ATCOR3还原了下垫面的原貌,校正效果优于ATCOR2。

The algorithm of ATCOR3 was introduced. Then the algorithm was applied to correct two scene TM imageries of Tongling and Huangshan of Anhui Province. By the method of eye comparison and NDVI analyzing, the effect of the correction was analyzed. The results show that the influence of haze on images is effectively eliminated. Atmospheric correction result by the ATCOR3 and the ATCOR2 was compared, and it indicated that the ATCOR3 restore was better than ATCOR2 when the original appearance of the surface was rugged terrain.
