QuickBird影像融合最佳波段选择及不同融合方法质量评价研究

Study on Optimal Band Selection and Evaluation Methods on Performance of QuickBird Remote Sensing Image Fusion

分析了QuickBird多光谱遥感影像各个波段的光谱特征,并进行了定量评价。根据信息量的大小和波段相关性得到最佳波段组合,在最佳组合波段下利用遥感影像处理软件ERDAS9.2选择或利用建模模块建立不同的影像融合模型对QuikBird多光谱数据与全色遥感影像进行融合,按照定性及定量指标对融合前后的遥感影像进行色彩、分辨率及信息量评价,得到QuikBird影像数据最佳融合方法。

The authors analyzed each band spectral features of the QuikBird sensor multispectral remote sensing image, and carried on the quantitative evaluation. According to the information and the band correlation optimal band combination, using remote sensing image processing software ERDAS9.2 established the resolution of high panchromatic remote sensing images with muhispectral remote sensing image of various fusion. Then compared the remote sensing images color, resolution and information evaluation by qualitative and quantitative index optimal the best fusion method.
