基于Android的地下管线三维可视化关键技术研究

Research on Key Technologies of the Underground Pipeline 3D Visualization Based on Android

针对基于二维地图的地下管线移动GIS应用难以准确描述地下管线复杂空间关系的缺陷,研究了基于Android实现地下管线三维建模及可视化的关键技术;设计了基于矢量空间数据的地下管线直管构造算法和弯管衔接算法;实现了Android地下管线三维可视化原型系统,以验证算法的可行性。

Because the underground pipeline mobile GIS applications based on 2D map were difficult to accurately describe the underground pipeline complex spatial relationships, this paper researched the key technologies of 3D modeling and visualization of underground pipeline based on Android. And then, the paper designed the algorithms of straight tubes and elbow connection 3D modeling based on vector space data. Finally, this paper realized an underground pipeline 3D visualization prototype system based on Android, which verified the feasibility of the research.
