以浙江省德清县ALOS影像为基础数据，探讨了利用乘积法、高通滤波法、小波变换、HIS变换、Brovey变换、PCA变换、Gram-Schmidt变换等七种影像融合方法，对ALOS全色与多光谱影像进行融合，对各方法的融合结果进行了定性和定量分析。实验结果表明，Gram-Schmidt变换在保持多光谱影像光谱信息的同时，显著提高了融合影像的空间分辨率，是最适合ALOS全色与多光谱影像的融合方法，为ALOS影像应用提供了参考。

Taking ALOS image of Deqing County as the foundation data , seven kinds of image fusion methods are dis-cussed, such as product method, high pass filtering, wavelet transform, HIS transform, Brovey transform, PCA transform, and Gram-Schmidt transform .The ALOS panchromatic and multi spectral image is fused , and the qualitative and quantita-tive analysis on fusion results is obtained .The experimental results show that Gram-Schmidt transform keeps the multi spec-tral image spectrum information , and at the same time , it also significantly improves the spatial resolution of the image fu-sion, which is proved to be the most suitable fusion method of ALOS panchromatic and multi spectral image , providing ref-erence for the application of ALOS image .
