| 随着计算机和遥感技术的不断发展，遥感图像解译方法也不断发展，但目视判读仍然是遥感图像解译中最重要的一种方法。如何从ETM+多光谱影像中选择出3个最佳波段并彩色合成成为遥感图像处理是一个重要的研究课题。首先分析了ETM+多光谱影像的波段特征及常见的波段组合；然后综合运用单波段的亮度差、均值、标准差、信息熵等统计特征方法，波段间相关系数矩阵方法，最佳指数法，联合熵法，典型地物光谱特征曲线法相结合分析顺德区ETM+多光谱影像，并从中选择出最佳波段组合；最后反复测试了6种赋色方案，最终的试验结果表明：对于顺德区这种典型的珠江三角洲河口平原地区的土地，利用遥感制图，ETM+遥感影像的543(RGB)波段组合为最佳目视解译波段组合遥 |

| With the continuous progress of computer and remote sensing technology, the methods of imagery interpretation are also developing, but visual interpretation is still an important means. How to choose three optimal bands to composite colorful image is a meaningful research topic. In this paper, we analyzed the band features of ETM+ multispectral imagery and common band combination firstly, then we applied various methods to analyze ETM+ imagery of Shunde district, such as statistical characteristic of single band,correlation coefficient matrix between bands, optimum index factor, joint entropy, characteristics spectral curve for typical objects. Finally six assignment schemes of color channel were tested repeatedly. Experimental results showed that bands combination of band 5(Red), band 4(Green), band 3(Blue) is the best for ETM+ multispectral imagery in Shunde district where is a typical Pearl River Delta river plain area. |
