| 摘 要： | 对卫星云图进行云地分离、云分类、云高估计等定量计算,并利用这些定量结果,用OpenGL进行三维建模,首先叠加地形,然后以混合的形式实现半透明与非透明云及全透明的地表区别显示,以云顶高估计结果作为云高,高程作为地面高度进行三角网格绘制,最终实现与实际云团基本相一致的三维云图。

| Abstract: | By the way of quantity estimation of the satellite image,including the cloud/surface detachment,cloud classification,cloud top estimate etc,this paper can model the three-dimension of cloud by the estimated product.First of all,added the terrain,then distinguish the transparent and semi-transparent cloud by blend of the texture,and set the alpha as zero of the clear area,drawing the triangle grid by the cloud height estimate product and DEM,we model the three dimension cloud which can be consistent with the real cloud in the gross. |
