| 摘 要： | 基于三维城市模型的路径导航方法,是指在三维场景中进行路径的选择并引导视点飞行。其过程如下:首先将三维场景显示到主框架窗口中,并将道路数据读入到计算模块中,然后用户通过选择起始位置和终止位置,自动计算视线方向,以及路径拟合的方式和等高飞行的高度值等,并在道路数据中根据节点信息求解一系列的控制点,最后根据所求得的点序列构建导航所需的实际路径,并进行坐标内插,驱动场景前进,实现动态导航。

| Abstract: | Path navigation method based on 3D city model refers to choose a path in a three -dimensional scene and guide the view-point flight.The process is as follows： First, the three-dimensional scene to the main frame window is displayed , and the data is read into the path calculation module , and then the user by selecting the start position and end position , gaze direction and automati-cally calculates the path and contour fitting way flying height , etc., and in accordance with the road data node information to solve a series of control points , and finally build the actual navigation path based on the desired point sequence obtained , and the coordinates of the interpolation driving scene forward , to achieve dynamic navigation . |
