| 摘 要： | 在进行空中和地面遥感观测时,从不同高度和方位观察同一地物,会发现其亮度和对比度等特征将发生明显的变化。而且,这种差异不仅与太阳入射角及观测角度有关还随物体空间结构要素的变化而变化。文章通过6S辐射传输模型仿真分析了土壤、植被、水体以及城市的双向反射特性及其对遥感成像的影响,重点结合Quick Bird图像和真实场景比较...

| Abstract: | The gray distribution and contrast of the optical satellite remote sensing imagery in the same kind of ground surface acquired by sensor is quite different,it not only depends on the satellite's observation and the sun incidence orientation but also the structural and optical properties of surface.Therefore,the objective of this research was to analyze the different BRDF characters of soil,vegetation,water and urban surface and also their BRDF effects on the quality of satellite image through simulation usi... |
