摘要
CBERS-02B星搭载了高分辨率全色相机HR和多光谱传感器CCD,HR和CCD分别具有高空间分辨率和高光谱分辨率的特点。对这两类影像进行融合可以得到尽可能完整和准确的地物观测影像。对北京地区CBERS-02B的HR和CCD影像分别用HSV变换、HPF变换、Brovey变换、HIS变换、SFIM变换和小波变换等融合方法进行融合,对融合结果从空间细节和光谱保持两个方面分别定性和定量地进行评价,并比较这几种融合算法在CBERS-02B的HR和CCD遥感影像融合中的效果,得到了几种比较合适的融合方法。
CBERS-02B carries a high-resolution and panchromatic HR camera and a multi-spectral CCD sensor. HR is high spatial resoluted and CCD is high spectral resoluted respectively. A intergrated and precise image can be acquired by fusing these two images. HSV, HPF,Brovey,IHS,SFIM and Wavelet transform are used to fuse Beijingeimage of CBERS-02B HR and CCD. Through preservation of spatial detail and spectral information,fusion results are evaluated qualitatively and quantificationally. Several appropriate transforms are gained then.
