| 摘 要： | 随着多源遥感影像融合技术的成熟发展,如何提高高分辨率遥感数据的利用效益和使用质量已经成为影响其应用效果的瓶颈问题.针对Qucik Bird-2高分遥感数据光谱分辨率不足等问题,结合ASTER多光谱遥感数据,引入3种融合方法:主成分分析(PCA)融合、小波PCA融合和基于小波的IHS(色度、亮度、饱和度变换)融合,实现了对多光谱图像和高分辨率图像的融合,得到了多光谱高分辨率影像,使得在增强影像空间分辨率的同时也尽可能地保留了影像的多光谱信息.最后对3种融合方法的结果进行了定性和定量评价.

| Abstract: | With the mature development of multisource remote sensing image fusion technology, how to improve the efficiency and quality of high resolution remote sensing data has become a bottleneck problem for its application effect. Aiming at the problem of low spectral resolution of QucikBird-2 high resolution remote sensing data, combining with ASTER multispectral remote sensing data, three fusion methods, namely PCA fusion, wavelet PCA fusion and IHS fusion based on wavelet are introduced to realize the fusion of multispectral and high resolution images and obtain multispectral high resolution imagery, which enhances the spatial resolution of image and at the same time retains the multispectral information as much as possible. Finally, qualitative and quantitative evaluation is conducted on the results of three fusion methods. |
