摘要
采用建立流程化模型的方法对Landsat7pan数据与多光谱数据进行融合,并分别用乘积变换、Brovey算法、IHS变换进行了试验。其中,用乘积变换算法做了大量的工程实现。实践表明,采用建立流程化模型的方法直观、简单、快捷,而且在操作上比较灵活,可以根据实际情况进行设计,避免固定流程算法所带来的输入输出格式转换,为大批量数据的快速生产提供一种有效方法。
This paper presents a modularization method of data fusion for Landsat imagery. The principle of the method and some data fusion algorithms like multiplication, Brovey, and IHS have been discussed. The experimental result shows that such an approach is very effective, convenient and flexible. On the one hand, the algorithms can be designed according to the users' requirements and the data fusion can be easily realized; on the other hand, the technique can avoid some processes of data format transfer and save a lot of time.
