摘要
随着遥感技术的发展,SPOT-5卫星数据以其优越的性价比,得到了较多的应用.在阐述遥感图像融合原理的基础上,以SPOT-5全色与多光谱影像为数据源,应用IHS变换、PCA融合、Brovey变换、乘积变换和HPF融合等5种比较常用的融合方法,从提高空间分辨率和保持原始图像光谱信息的角度进行了分析评价,探讨最适合于SPOT-5图像的融合方法.结果表明：在各种融合方法中,HPF与IHS融合的效果最好.
With the development of remote sensing,the application of SPOT-5 data are extensive for its advantages.With the principles of image fusion methods,this paper focused on finding a proper method for fusing the panchromatic and multi-spectral images of SPOT-5 with IHS transformation,PCA resolution,Brovey transformation,multiplicative and HPF resolution.Results of different fusion methods were analyzed in terms of special resolution enhancement and spectral information maintenance.The results showed：HPF and IHS resolution had the best quality.
