光学遥感影像融合方法的研究

Study of optic remote sensing image fusion methods

随着新型传感器的出现,获取遥感影像能力的不断提高,遥感影像种类和总量急剧增加,遥感影像融合为多源数据的处理、分析与应用提供了新的途径。为了比较不同类型融合方法的作用效果,在简要介绍HIS、Broevy、Wavelet 3种方法及标准差、信息熵、偏差指数、相关系数4种评价指标后对Landsat7 ETM+数据进行了融合实验,并就结果做主客观分析,最后完成3种融合方法性能的总体比较,为相关工作提供参考借鉴。

With new sensor appearing,the capability of acquiring remote sensing image is always processing,kinds and amounts of image are also rapidly increasing.Remote sensing image fusion provided a new route for manage,analysis and application of multi-source data.For comparing effects of the different types methords,this passage firstly introduced HIS,Brovey,Wavelet three kinds fusion methods and four fusion evaluation guideline,and then did fusion experiment with Landsat 7 ETM＋data,and then analysed the results,at last compared total capability with three fusion methods.
