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 problem of the lack of research on the data fusion of the resource No.1 02C and the Landsat8 satellite image in the past, this paper uses the former to be superior to the latter in the spatial resolution, the latter has the characteristic that the former does not have the spectral information, Transformation method, ratio transformation method, color transformation method, high-pass filtering method and super-resolution Bayesian method five fusion methods, respectively, the two data itself and the data fusion between, and the use of qualitative and quantitative methods of fusion results The results show that high-pass filter method and super-resolution Bayesian method are better in the fusion result of the data of No.2 02C satellite panchromatic and multispectral bands. The high-pass filter method of the results of fusion between panchromatic and multispectral data of Landsat 8OLI, The best result is that the high-pass filtering method is the best one in the fusion result of OCT 02C satellite panchromatic band and Landsat 8OLI multispectral data.
