| 摘 要： | 应用比值变换、IHS变换、主成分变换和合成比值变量变换等4种影像融合方法对QuickBird多光谱和全色遥感影像进行融合,并利用偏差指数、平均梯度等指标对融合效果进行定量评价;运用最佳指数因子确定参与成图的多光谱影像的波段．研究结果表明,合成比值变量变换法的融合效果最佳;最优波段组合为431,并在此基础上建立了地物判读分析依据,用于QuickBird遥感影像目视解译;采用容差格网矢量化技术进行遥感影像的屏幕矢量化,制作了1：2000比例尺农业园区底图。

| Abstract: | As a case study of merging QuickBird multispectral and panchromatic remote sensing image, Brovey,IHS,PCA and Synthetic Variable Ratio(SVR) are choosen and their merging effects are evaluated quantificationally by difference index and average gradient; bands of merged image choosen to produce basic map are determined by optimium index factor(OIF). It is indicated that merging effect of SVR is beyond orther 3 algorithms;the optimal band combination is 431 which is applied to establish identification and analyse criterion of substances on earth surface for visual interpretation;tolerance-grid-digitalization method is used for screen-digitization in producing basic map for agricultural zone. |
