利用我国自主研制的环境一号小卫星A星上搭载的CCD相机与高光谱成像仪(HSI),以洪河国家级湿地为研究区,进行融合实验。先分析了两种载荷的特点,然后根据载荷特点,设计并评价了两种载荷数据融合的方法。结果表明,由于A星CCD相机与高光谱成像仪成像条件相似,可以对两个载荷的数据进行融合,得到具备较高分辨率与光谱分辨率的数据,为后续高精度分类制图、目标识别、信息提取等应用提供高质量数据源。 更多还原

【Abstract】 The paper tried to fuse Hyper Spectral Imager(HSI)and CCD data of HJ-1A Satellite which was developed by China independently.At first,we chose Honghe wetland as study area,and analyzed the data features of the two sensors;then we designed a fusion method based on these features and evaluated the fusion result.Finally,The paper reached the conclusions:(1)Due to the similarity of the imaging condition,the CCD and HSI data can be registered with each other well and then can be fused to acquire the ... 更多还原
