摘要
CBERS-02B星搭载了高分辨率全色相机HR和多光谱传感器CCD,HR影像可以与CCD影像融合,优势互补形成新的影像,既保持HR的高空间分辨率又保持CCD的光谱分辨率,HR影像同样可以与其它传感器影像融合形成新的影像。本文使用6种不同的融合方法融合HR与多光谱CCD以及SPOT5多光谱影像,并对融合结果进行了定性和定量评价,得到了HR与SPOT5多光谱影像融合较好的方法,表明了HR与其它传感器影像融合的潜力,同时也对HR和SPOT5多光谱融合影像及与CCD融合影像进行了初步的对比分析。
CBERS -02B satellite has a high resolution camera HR and a multi - spectral sensor CCD. HR and CCD images can be fused to form a new image which can preserve high spatial resolution of HR and high spectral resolution of CCD. HR image can also be fused with images of other sensors. The authors used six methods to fuse HR, CCD and SPOT 5 multi - spectral images and evaluated the fusion results qualitatively and quantitatively. As a result, relatively ideal methods for fusing HR and SPOT 5 multi - spectral images were found. The results indicate the potential capability of HR images for being fused with images of other sensors. A comparison has also been made between the HR ＆ SPOT 5 multi - spectral fusion image and the HR ＆ CCD fusion image.
