基于ERDAS IMAGINE9.2操作平台的遥感图像融合概述

摘要

随着遥感技术的迅猛发展,各种遥感数据相应呈现。如何让数据得到充分的应用？数据融合在当今社会显得越来越重要;如何更好地对数据进行融合？我们必须了解各种融合方法的优缺点。本文介绍了ERDAS IMAGINE9.2操作平台上的几种遥感图像融合,分别是分辨率、小波变换、改进IHS、高通滤波融合,并通过实验比较几种融合方法的优缺点以及探讨未来可能研究方向。%With the rapid development of remote sensing technology,there appears a variety of remote sensing data.How to get a full application of the data Data fusion has become increasingly important in today＇s society,then how to integrate the data better？ We must understand the advantages and disadvantages of the various fusion methods.This paper describes several kinds of remote sensing image fusion of the ERDAS IMAGINE9.2 platform,namely,resolution ratio,wavelet transform,and improvement of the IHS,high-pass filter fusion,and discusses the advantages and disadvantages of the future research direction through the experimental comparison of several fusion method.
