摘要
阐述了基于SAR影像的洪水淹没范围快速提取的融合方法,并为此设计了一个模型。融合的过程通过HIS变换、比值运算法、主成分分析法3种方法来实现。就目前的效果而言,达到了快速提取的目的,但有些问题还有待解决。
This paper discussed the fusion method on the quick extraction of flooding area information based on SAR image and designed a model. It applied three methods to implement the fusion procedure, including HIS transformation, multiplicative arithmetic transformation, and principal components analysis transformation. The results showed that it can achieve the objective of quick extraction. But there are some problems to be solved.
