QuickBird遥感影像信息融合方法比较

Comparative Study on Fusion Methods of Quickbird Remote Sensing Images

本文以甘肃省张掖市大野口水库的QuickBird全色和多光谱数据为例,采用HSV变换法、Brovey变换法、Gram-Schmidt变换法和主成分变换法对该影像进行融合,并从定性和定量两个方面对4种影像融合方法进行对比。结果表明,主成分变换法是最适合的融合算法。

Taking the QuickBird panchromatic and multispectral data of Dayekou reservoir in Zhangye City,Gansu Province as an example,the image was fused by HSV transform,Brovey transform,Gram-Schmidt transform and principal component transform,and the four image fusion methods were compared qualitatively and quantitatively.The results show that the principal component transform method is the most suitable fusion algorithm.
