摘要

全球变化研究需要将多种传感器光谱波长接近的图像波段一起使用

以满足遥感应用对时间分辨率和区域覆盖的要求

这给遥感图像处理提出了新要求

涉及多传感器多时相数据几何定位一致性问题、辐射归一化问题及地类属性标识一致性问题以及高度自动化处理的问题。针对上述几方面问题

提出了一个基于"不变特征点集"IFPs（Invariant Feature Points set）作为控制数据集的区域级遥感图像自动化处理框架

将图像的几何空间、辐射值空间和类别属性值空间的时空对齐问题纳入到统一框架

提供了一种间接快速处理的手段和理念

并对构建IFPs的关键技术进行了综述。

Abstract

Global change research consistently requires the combined use of cross-sensor images with similar spectral wavelengths. To meet the temporal resolution and coverage requirements of remote sensing applications

new requirements are proposed for remote sensing image processing technology. Such technology requirements are related to how to obtain geometric consistency between cross-sensor/multi temporal data

how to obtain radiometric normalization

and how to obtain land cover class labels that are consistent between cross-sensor/multi temporal data. They are also related to highly automated processing. For the above requirements

we propose a framework for the automatic processing of remote sensing images with "an invariant feature point set"（IFPs） as the control data set. Specifically

we combine the spatial and temporal alignment in geometry space

radiation space

and land cover class space into a unified framework and thereby provide an indirect means to achieve fast processing. The key technologies for building IFPs are also reviewed.
