资源简介

摘要: 对资源三号卫星(ZY\|3)数据影像特征进行科学分析与应用研究,为ZY\|3数据优化利用与广泛应用提供可靠的借鉴。分别从单波段数据信息量、多波段数据相关性及各波段数据地类间可分性分析原始数据,ZY-3多光谱数据以band4信息量最丰富,与其他波段相关性小,地类间光谱距离最大,其次是band3与band2,而band1各项指标最差。将band4、3、2组合后,进行多光谱数据与全色数据分辨率融合,进一步分析融合后数据,对于土地覆被调查,主成分分析影像视觉最好,而乘积方法信息量最丰富。 关键词: 影像特征分析;  信息量;  相关性;  地类间可分性;  东北界河地区;  ZY-3     Abstract: According to the needs of the project this study can provide reliable reference for the optimization and widely use of the data of ZY\|3 based on the scientific and applied researches on the images features of ZY\|3.In this paper,spectral characters in ZY\|3 are analyzed from three aspects: single band data information content,multiband data correlation and the class separability of each band data.Through the analysis,we can get that Band4 of ZY\|3 is the most satisfying band for its richest information content,minimal band correlation and maximum spectral range between classes.The following are band3 and band2,and band1 is the least satisfying band in all indexes.The further analysis of Resolution merge of Multispectral and Panchromatic data after the combination of band2 & band3 shows the images of principal component transformation have the best visual effect,while the images of Brovey Transform have the richest information content.
