摘 要：
对CBERS-02B星高分辨率HR图像的应用潜力和精度进行了初步评价。以陕西省南部西乡县作为研究区,对HR图像进行辐射和彩色增强;采用多种算法对HR和CCD图像进行融合处理,从定性和定量两方面对融合前后的图像做了全面的评价;基于融合前后的影像进行了土地利用分类和精度对比评价。结果表明,HR和CCD图像的融合,使两者的优势得以互补,其中比值变换融合法在图像空间细节和光谱特征保留上具有一定的优势。融合后的图像明显提高了土地利用信息的提取精度,在国土资源调查与生态环境监测中具有广阔的应用前景。

摘 要：
This paper seek to evaluate the application potential and accuracy evaluation of CBERS-02B high resolution(Pan) data.Taking Xixiang County of Shaanxi Province as a test area,radiometric and color enhancement is performed to HR image;then the HR image was fused with the CCD images based on five algorithms, and image qualities are evaluated between original images and fused images in terms of qualitative and quantitative aspects.Finally,land-use categories were extracted and classification accuracy was evaluated based on the two datasets.The results show that land-use classification accuracy is improved greatly by fusion of 02B high resolution data and CCD data,and Brovey algorithm is best for keeping the spatial textures and spectral characteristics of images among five algorithms.HR image should be applied widely in resources investigations and ecological environment monitoring.
