影像融合技术在土地利用动态遥感监测中的应用研究

Application research of image fusion technology on dynamic monitoring of land use

国土资源部启动的全国土地利用动态遥感监测项目,通过分析不同时期的卫星影像,从中提取出土地利用变化信息。本文的研究工作,主要是基于作者近几年从事该项目研究与应用的实际,分别以SPOT系列数据、TM数据及QuickBird等中、高分辨率数据作为试验数据,进行影像不同融合算法试验,旨在研究多源遥感影像融合方法在动态监测项目中的应用,并对融合结果进行定性、定量两方面的比较分析,探讨适合土地利用动态遥感监测的融合方法。

The Ministry of Land and Resources P.R.C has initiated national remote sensing dynamic monitoring project of land use.Through analysis of satellite images of different periods,land use change information can be extracted and analyzed.The research work is mainly based on the operator experience engaged in the project in recent years.And this paper studies various image fusion methods in the application of dynamic monitoring project,and then summarizes some ways benefiting the future project application,with the aim of promoting this field of research further forward.
