中文摘要：

为寻求更加适合与天绘一号（TH-1）Z星全色影像融合的多光谱数据及融合方法，运用IHS，Wavelet，PCA，P＋XS，Brovey5种变换方法，分别将TH-1全色影像与TH-1，TM，ETM的多光谱影像进行融合，从视觉和定量两个方面对融合效果进行分析．结果表明：①3种融合组合方式中，TH-1PAN与TH-1MS的融合质量最高；②5种融合方法中，Wavelet变换光谱信息保持效果最佳，P＋XS和Wavelet变换的空间信息保持效果较佳，Brovey和IHS融合的综合质量最佳．

英文摘要：

In order to find suitable multispectral images and fusion methods for the pan-sharpening of TH- 1 panchromatic images, IHS, Wavelet, PCA, P＋XS, Brovey five transformation methods were used to separately fuse TH-1 PAN with TH-1 MS, TM MS and ETM MS, and the fusion results were assessed from visual and quantitative aspects. Results show that TH-1 PAN and TH-1 MS fusion combination have the best quality; Wavelet transformation can keep the best spectral information, P＋XS and Wavelet transformation can keep the best spatial information, and Brovey and IHS can get the best overall quality.
