摘　　要：针对以往关于资源一号02C和Landsat8卫星影像数据融合的研究不足的问题,该文利用前者在空间分辨率上高于后者、后者具有前者所不具有的光谱信息这一特性,选取主成分变换法、比值变换法、色彩变换法、高通滤波法和超分辨率贝叶斯法5种融合方法,分别对两种数据本身及数据间进行融合,并利用定性与定量的方法对融合结果进行评价,得出:资源一号02C星全色波段与多光谱波段数据融合结果中高通滤波法与超分辨率贝叶斯法效果较好,Landsat8OLI全色波段与多光谱数据融合结果中高通滤波法效果最好,资源一号02C星全色波段与Landsat8OLI多光谱数据融合结果中高通滤波法效果最好。Aiming at the insufficiency of the study on the image fusion of ZY-1 02 Cand Landsat8,the paper performed the fusion through the data and data integration by five methods of PCA,Brovery transform,HIS,HPF and Pansharp,based on the characteristics that ZY-1 02 Chad higher spatial resolution than Landsat8,while Landsat8 had more detailed spectral information than ZY-1 02 C.Finally,it evaluated the fusion by qualitative and quantitative methods.Result showed that HPF and Pansharpe would have better effect in the fusion between the panchromatic band and the multi-spectral data of ZY-1 02C;HPF would have better effect in the fusion between the panchromatic band and the multi-spectral data of Landsat8OLI;and HPF would have better effect in the fusion between ZY-1 02 Cpanchromatic band and Landsat8 OLI multi-spectral data.
