不同遥感影像融合方法在地理国情普查中的应用对比研究——以海南北部地区为例

利用比值变换融合、高通滤波融合、改进IHS融合、小波变换融合和基于主分量变换等图像融合方法对IKONOS多光谱影像和IKONOS全色影像进行融合,结合地理国情普查的地表覆盖类型,对比融合后影像的特点,并分析评价对比结果,为地理国情普查工作选用合适的融合方法生成效果较好、地物清晰的遥感底图,从而为提高解译效率提供参考依据。

Analysis Research of Different Remote Sensing Image Fusion Methods Applying on Geographical Conditions Census:Take Northern Area of Hainan as Example

This paper used Brovey Transform fusion,High-pass Filtering fusion,improved IHS fusion,Wavelet Transform fusion and Principal Component transformation fusion of IKONOS multispectral images and IKONOS panchromatic image.This paper combined the surface coverage type of geographical conditions census,compared the characteristics of fused image,and analyzed the results,for providing reference basis for geographical conditions census to choose appropriate methods of generating remote sensing image with good effect and clear features to enhance the efficiency of image interpreting.
