| 摘 要： | 将城市主体结构简化为两侧为建筑物中间为道路的街道结构,并假定街道径直走向,在一个 像元内为无限长,采用几何光学的方法分别计算楼房顶部、竖直墙面以及道路对像元辐射值的贡献.从而构 建了大尺度下城市主体结构的二向反射率因子(BRF)模型.在微尺度上考虑了城市结构自身表面的BRF 模型,由于在某个城市像元中还可能存在植...

| Abstract: | The city main structure was simplified to the street structure in which both sides are buildings and the middle is road.The street structure was assumed straight forward and infinite within a pixel,the contribution of pixel radiance from the top of the buildings,the vertical walls and the road was computed respectively using geometrical optics method.Then the bidirectional reflectance function(BRF)of the main structure of the city was constructed in large scale.In the micro-scale,the BRF of the structure su... |
