摘　　要：CBERS-02B星可同时获取高、中、低三种空间分辨率遥感数据能力,极大地拓展了其应用领域与潜力。由于CBERS-02B星HR全色影像和多光谱CCD影像数据的空间分辨率相差太大,融合后影像地物边界出现明显虚假晕边现象,直接影响地物识别和制图效果。论文在分析融合影像质量影响因子的基础上,根据02B星数据特性提出了一种新的影像融合策略,试验结果表明该方法能有效地提高融合影像质量和改善地物识别能力。CBERS-02B can acquire different spatial resolution and multi-spectral data which improves its application ability greatly.However,the spatial resolutions of HR and CCD are different so largely that resolution merge often cause some problem such as spectral distortion.In this paper,we proposed a two step resolution merge method of HR and CCD data of CBERS-02B.The result shows that the method is effective and can improve the final result of resolution merge compared with the normal method.
