多源遥感影像数据的融合方法探讨

Discussion on the Methods for Multi-source Remote Sensing Image Fusion

在分析和总结多源遥感影像数据融合的基础上,探讨了多源遥感影像数据融合的层次、模型、结构及其特点,归纳总结了多源遥感影像数据融合方法,目的是提高多光谱影像分辨率的同时保持色调不变,从另一个角度理解为在已知低分辨率多光谱影像和高分辨率全色影像的基础上,模拟生成高分辨率多光谱影像。本文介绍了遥感影像融合技术,系统阐述了几种常见的遥感影像融合方法及其应用。

This paper discussed the level, model, structure and characters of multi -source remote sensing image fusion based on the analysis and summary of multi - source remote sensing image fusion. Then it concluded and summarized the methods of multi - source remote sensing image fusion to improve the spatial resolution of multi -spectral image and keep the tone. From another aspect, it produce high spatial resolution multi - spectral image using low spatial multi - spectral image and high spatial resolution panchromatic image. This paper introduced the techniques of remote sensing image fusion, discussed some common methods and applications of remote sensing image fusion.
