| 摘 要： | 遥感图像融合可以发挥多源遥感数据的优势。但由于不同传感器的遥感数据有着不同的特征，不同数据所采用的融合方法也应不同。文章探讨了ASTER多光谱波段与SPOT全色波段数据融合的方法，通过对PCA融合、IHS融合和基于小波的IHS融合方法的对比研究，得出基于小波的IHS融合法在提高空间分辨率的同时较好地保持了地物的多光谱信息。 |
| 关 键 词： | ASTER SPOT 影像融合 基于小波的IHS融合 |

| Abstract: | The fusion of remote sensing images can take advantage of multi-resource RS data. Since the data from different kinds of remote sensor have different characteristics, the corresponding fusion method applied to different data should also be different. After discussing the fusion method of ASTER multispectral and SPOT panchromatic wave bands, and contrastively analyzing PCA, IHS and the IHS fusion based on wavelet transformation, it has found out that the IHS fusion based on wavelet transformation is better for keeping multispectral information of overground objects with heightening the spacial resolution as well. |
| Keywords: | ASTER SPOT image fusion IHS fusion based on wavelet transformation |
