| 摘 要： | 在不同自然景观区的遥感蚀变信息检测中,背景与干扰是2个复杂而又容易混淆的研究对象。本文结合光谱混合模型理论与随机变量概率分布相关理论,深入分析了遥感数据的光谱空间几何结构特征(重点剖析二维散点图),系统研究了背景与干扰的关系、复杂度以及干扰地物类型的划分等问题。这些问题的探讨为遥感蚀变信息检测的最佳方案设计和蚀变信息潜在性评价与准确提取提供了技术思路。

| Abstract: | The background and interference in remote sensing alteration information detection in different landscape units are two complicated and easily confused study objects.In this paper,the spatial geometric structural characteristics of spectral data of the remote sensing image are analyzed thoroughly.In addition,the relations between the background and the interference,the complexity of their relationship and the classification of the interfering objects are studied systematically in combination with the theories of spectral mixing models and probability distribution of stochastic variables.The discussion of these problems has provided important technical ideas for designing the optimal scheme for remote sensing alteration information detection,evaluating potentiality of the alteration information,and extracting the alteration information accurately. |
