中文摘要：

以高空间分辨率的全色影像为引导,高光谱分辨率的多光谱数据作为已知条件,利用泊松方程插值方法对各个波段影像在空间维进行插值,最终得到的多光谱影像既具有原多光谱影像的光谱信息,同时又具有全色影像的清晰细节。该方法还具有不受波段数目限制的特点,与多重网格方法结合可以提高数据处理效率。使用该融合方法对QuickBird和IKONOS数据进行融合实验,实验结果在RASE、ERGAS、空间细节质量、SSIM等多项质量指标上优于传统融合方法。

英文摘要：

Multispectral image is interpolated in each band using Poisson equation with pan- chromatic image as guidance based on the known condition. The resulting multispectral im- age keeps most spectral information of original one and possess clear details as the same as panchromatic image. The method works without limitation of hand quantity and association with Multigrid solver improves efficiency of data processing. The values of quality index on RASE, ERGAS, spatial detail and SSIM of the proposed new method do well or better com- pared to traditional image fusion ones in experiment on QuickBird and IKONOS images.
