| 摘 要： | 遥感图像的数据融合是当前遥感界研究的热点问题之一。论述利用小波变换提取合成孔径雷达（SAR）图像的多尺度纹理信息，基于小波纹理信息将SAR图像与TM图像进行融合。选取徐州市南郊风景区的Radarsat卫星SAR图像和TM图像进行试验研究，并与颜色变换法融合图像进行对比分析，结果表明，无论是目视解译还是定量分析，该融合方法与颜色变换法相比，将获得更理想的高空间分辨率多光谱的融合图像。

| Abstract: | Data fusion on remote sensing images is one of the most important problems in current remote sensing field. This paper describes a method to extract multi scale textural information from satellite SAR image using wavelet transformation. Then data fusion between satellite SAR image and TM image is implemented based on the wavelet texture information. Experimental datum of Radarsat satellite SAR image and TM image which were obtained from south landscape in Xuzhou city were selected. To compare with fusion results, color transformation method is used in this article. The experiment results that were analyzed whether in vision or in quantity show that better fusion image with high spatial resolution and multi spectrum can be obtained by the method. |
