| 摘 要： | 随着遥感技术的发展，遥感图像的数据融合备受关注．本论述利用小波变换和IHS相结合的方法对Landsat7多光谱图像与全色图像进行数据融合．选取徐州市南郊铜山新区的图像进行试验，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，该融合方法均优于颜色变换法．

| Abstract: | Data fusion on remote sensing images is one of the most important problems in current remote sensing field. A fusion method, which combines wavelet transformation with IHS method, was described. Then data fusion between multi-spectral image and panchromatic image of landsat7 satellite was implemented using the method. Experimental data of Tongshan development area where is suited in south suburb of Xuzhou city were selected. To compare with fusion results, color transformation method was used. The experiment results that were analyzed whether in vision or in quantity show that better fusion image can be obtained by the method than that by color transformation method. |
