采用HSV、Brovey、Gram、PC几种常用方法对ZY-02C多光谱和GF-1全色波段进行融合,以光谱保真度和纹理清晰度为依据对各融合效果进行定量评价。结果表明:对ZY-02C多光谱与GF-1全色波段采用Gram和PC融合方法优于另外两种;得到的影像图件色彩丰富且地物纹理清晰,能近似真实地反映地物景观,也显示出ZY-02C多光谱的光谱信息与GF-1全色波段的空间信息之间保持很好的权衡。
Several common methods such as HSV, Brovey, Gram and PC were used to fuse the ZY-02C multi-spectral and GF-1 panchromatic bands. Quantitative evaluation of each fusion effect was carried out based on spectral fidelity and texture definition. The results show that the fusion method of Gram and PC is superior to the other two methods for the ZY-02C multispectral and GF-1 panchromatic bands; the obtained image is rich in color and the texture of the object is clear and can reflect the landscape of the object approximately, It also shows that there is a good trade-off between the spectral information of the ZY-02C multispectral spectrum and the spatial information of the GF-1 panchromatic band.
