摘要
为了提高云团的观测准确率,提出了利用红外云图夜间能够成像的特点,研究云图中灰度值与云团高度值存在的关系,利用该对应关系构建出云图的三维模型,计算各像素点的顶点法向量,对模型中各个像素点进行着色,最终设计并实现三维云图仿真系统。该系统能够有效解决云图的三维显示问题,极大地提高了云图的真实感,具有很强的实际意义。
In order to improve the accuracy of cloud image, put forward the characteristics of infrared cloud image can be used at night, the relationship between the gray value and height of cloud is studied, the three-dimensional model of cloud graph is constructed by using the corresponding relation, the vertex normal vector of each pixel is calculated, each pixel in the model is colored, finally, the 3 d cloud image simulation system is designed and realized.
