摘　　要：分别对遥感影像的5种融合方法进行了对比分析,明确了各融合方法相对原始影像光谱的扭曲程度,比较得出了在光谱特征上扭曲较小的融合方法.同时进一步对比分析了光谱扭曲程度较小的融合影像在图像分类识别上的精度.On the basis of the study from the forefathers, this paper is designed to analyze each of the five fusion models on the RS image comparatively. This study examines the properties of fused images and their ability to preserve the spectral integrity of the original multispectral image. Through the results, this study finds the models which distort the original multispectral image to a lighter extent. Then this study has a further comparative analysis of the imagery classification recognition accuracy of the lighter distorted fused image and the muhispectral original image.
