基于混合像元光谱信息的正交试验设计与交互作用分析

Orthogonal Test Designing and Interaction Analysis based on the Spectral Information of Mixed Pixels

中文摘要英文摘要

混合像元问题不仅是遥感技术向定量化深入发展的重要障碍,而且也直接影响计算机处理地物的自动识别和分类精度。来自非朗伯体表面的反射不仅具有多角度、多方位空间分布特征,还具有偏振性。本文旨在通过对最常见的混合像元--植被-土壤混合像元为例,分别对其进行不同偏振角度和不同面积比例的高光谱特性分析,同时进行科学地正交试验设计与交互作用分析。结果发现,波段、偏振角度和植被-土壤混合像元的面积比例均可对混合像元的高光谱特征产生影响,且这些影响是通过因素间的交互作用体现的。这对利用偏振遥感信息与高光谱信息进行混合像元分解与融合,进而实现目标识别、分类及促进定量遥感发展均有重大的理论意义与广泛的应用前景。

Mixed pixels are not only a major obstacle to the development of quantitative remote sensing. They also seriously affect computer processing in the field of remote sensing. Lambertian surface not only has the spatial distribution with multi-angle and multi-directional characteristics, also has the polarization. This paper aims to the most common mixed pixels-vegetation-soil mixed pixels as an example, analyzed the hyperspectral curves under different polarized angles and different area ratios, and designed an orthogonal experiment scientifically. The result was found that the above factors and their interactions could impact on the hyperspectral characteristics of mixed pixels, which has great theoretical significance and wide application prospect on the use of mixed pixels fusion by polarization and hyperspectral remote sensing, thus achieving target identification, classification and promote the development of quantitative remote sensing.
