摘要
从卫星影像的成像过程出发 ,揭示了卫星影像所含信息的物理内涵 ,从频率域特性出发得出了高空间分辨率影像和多光谱影像可以融合的物理基础 ,为寻找一种较好的融合方法提供了理论依据。
Since the successful launch of various kinds of remote sensing satellites,there are many kinds of remote sensing satellite images available. Information extraction from those remote sensing data sources usually requires to analyze those data sets together,and to visualize on a media such as paper,photo,monitor,etc.Image fusion is a technique to do so.This paper traces the processes of image formation,analyses the basic physical theory about remote sensing image fusion in frequency domain,and provides the frequency domain basis on how to design a proper image fusion algorithm.
