| 摘 要： | 在IRS—P6遥感影像的多光谱与CBERS-2B遥感影像的全色PAN波段之间进行融合，对乘积变换、比值变换、IHS变换和主成分分析4种常见的融合方法进行对比分析，并对融合后的影像进行主观定性评价和客观定量评价。研究表明：IHS变换效果相对最优，在较好地保持原多光谱影像光谱信息的同时，大大地提高了影像的空间分辨率，对云区的地物色彩表现力上也较好。研究对于使用多源遥感影像融合获取高质量影像有着重要的参考价值。

| Abstract: | A fusion between multi-spectral bands of IRS-P6 remote sensing image and the panchromatic band PAN of CBERS-2B remote sensing image had been carried out, the comparative analysis of 4 common fusion methods （Multiplication transformation, Brovey transformation, IHS transformation and Principal Component Analysis） had been made, then the subjective qualitative evaluation as well as the objective quantitative assessment of fused images had also been done. The results showed that the IHS transformation exhibits a relative optimum effect, which could greatly improve the spatial resolution of images while keep the spectral information of original multi-spectral images, besides, it also hada good expression of ground features color in cloud fields. The study had a very important reference value for getting high-quality images by using the multi-source remote sensing image fusion. |
