公路三维模型建立与数据组织

3D Modeling and Data Organization of Highway

    摘要
  • 摘要: 以公路设计数据为基础,讨论了地形、公路及其构造物的三维模型的建立方法。针对公路呈线性分布的特点,采用动态分段技术来组织管理路面三角形数据及道路属性数据,并在三维环境下,对经典的二维线性参照系统进行扩展,使之能满足公路附属设施三维模型的定位及其位置查询,并在具体项目中得到验证。

     

    Abstract: On the basis of design data, this paper discusses the 3D modeling methods of terrain, highway and attached establishments, taking into account the linear distributing feature of road, organizing and managing road triangles and attribute data, by dynamic segmentation technology.To meet position and location of attached establishments 3D model in 3D landscape, the traditional LRS is extended.Finally, an experiment system is developed, and the methods described above are examined.
