遥感影像的云及其阴影覆盖区光谱重构
Spectral Reconstruction of Remote Sensing Image's Clouds and Its Shadow Coverage
摘要
Abstract
Previous method of cloud and its shadow removal in the remote sensing image focus on the geometrical characteristic recovery of coverd terrain,this method is against the information extraction based on the spectral characteristics. A method based on the spectral characteristics of covered terrain category reconstruction was proposed. Adopt two adjacent years phenophase remote sensing data, use normalized difference value and decision tree classification method to detect the thick cloud and its shadow,and extract corresponding regional surface coverage type information, in remote sensing image of two various bands,do the linear regression analysis to each surface feature of the covered terrain,to obtain the reconstructed data of the covered terrain. The experimental results show that the method can recover the geometry information of the covered terrain,and it also realizes its spectral information simulation.关键词
