摘要: 为寻求更加适合与天绘一号(TH-1)卫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,Brovey 5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-1 PAN与TH-1 MS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.

关键词: TH-1, 影像融合, 融合质量评价

Abstract: 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.

Key words: TH-1, image fusion, fusion quality assessment
