| 摘 要： | 遥感信息融合（Fusion）是目前遥感应用领域的一个热点问题。高分辨率的全色影像与多光谱彩色低分辨率的遥感数据叠加，可以最大限度地利用不同分辨率、不同光谱信息和不同时相分辨率的遥感信息。融合中对同一地区长江流域秭归段的TM4、3、2多光谱和TM8高分辨率的遥感影像采用了IHS变换、分辨率（主成分分析）融合方法进行了数据融合，并对不同的融合方法所得到的融合影像进行目视和统计特征的分析与评价。

| Abstract: | Data Fusion is a currently hot spot in the field of remote sensing application. Different fusing methods can get different fusing results. Namely, it can get different fusion image.It is commonly used to enhance the spatial resolution of multispectral image using higher spatial resolution panchromatic image. Based on the software platform, remote sensing image fusion is discussed by HIS transformation and PCA transformation. Meantime, with the fusion method, higher spatial resolution TM8 band is fused with the Land sat TM multispectral image. The resultant images are evaluated qualitatively and quantitatively. Through the visual qualitative analysis, give some conclusions about nowadays data fusion of remote sensing image. |
