遥感影像融合方法的比较与评价

Comparison and Evaluation of Remote Sensing Image Fusion Methods

本文选取5种不同的融合方法,分别对高分二号(GF-2)全色波段遥感影像与Landsat-8多光谱遥感影像进行融合。通过定性评价和定量评价相结合的方法,对5种融合方法进行了比较。结果表明不同融合方法在应用方面有不同的适用性,在水体信息提取方面的应用上,PCA融合方法最适用;在植被与道路信息提取方面的应用上,G-S融合方法最适用。

In this paper,five different fusion methods were selected to fuse the high resolution two(GF-2)panchromatic remote sensing image and Landsat-8 multispectral remote sensing image respectively.The comparison of the five fusion methods was made through the combination of qualitative evaluation and quantitative evaluation.The results show that that different fusion methods have different applicability in application,PCA fusion method is the most suitable in the application of water information extraction,and G-S fusion method is the most suitable in the application of vegetation and road information extraction.
