摘要
多时相遥感影像的辐射归一化是进行变化检测或拼接不可缺少的步骤。本文从绝对辐射归一化和相对辐射归一化两个方面对现有的多时相遥感影像辐射归一化方法进行了总结。对各种辐射归一化方法进行了剖析,并指出了这些方法的优缺点和适应性。最后对多时相遥感影像辐射归一化方法未来的发展进行了展望。
Radiometric normalization of multi-temporal satellite images is very important for change detection or image mosaic.Existing radiometric normalization methods can be categorized as either absolute radiometric normalization or relative radiometric normalization.The methods of each category are described and reviewed,including their advantages,disadvantages and adaptability in different situations.In addition,the development trends of radiometric normalization methods for analyzing multi-temporal satellite images in the future are discussed.
