【摘要】 受较大分辨率差的影响,OLI多光谱影像与SPOT-6 Pan影像直接融合可能导致融合影像色彩失真。若将OLI多光谱影像与全色影像融合后再与SPOT-6 Pan影像融合,在选用合适融合方法的基础上可得到较好的结果。以新疆伊吾县淖毛湖遥感地质解译为例,采用IHS变换法、Brovey变换法、PCA和Gram-Schmidt Pansharpening(GS)等方法分别对OLI和SPOT-6Pan进行间接融合,并利用主观对比和水平光谱剖面对比两种方法对融合影像进行综合分析与评价。经实地查证,基于OLI与SPOT-6 Pan(GS变换融合)融合影像解译获得的地质界线综合准确率达89.5%。更多还原

【Abstract】 Influenced by the low resolution, the fusion of OLI multi-spectral image and SPOT-6 Pan image may cause color distortion. Taking Yiwu Naomao Lake remote sensing geological interpretation for example, we used IHS transform, Brovey transform, PCA and Gram-schmidt(GS) Pansharpening to fuse the OLI and SPOT-6 Pan indirectly, and used the subjective comparison and horizontal spectral profile comparison to analyze and evaluate the fusion images. The field verification shows that the geological boundary accuracy interpreted by OLI and SPOT-6 Pan fusion image reaches 89.5%.更多还原
