利用地下管线探测点进行区域三维模拟

A small-area three-dimensional simulation using underpipe explored point data

作为一种直观的成果展示方式,三维模拟已经成为地下管线信息系统的必备工具。但是良好的三维显示效果需要高成本的DEM数据支撑,导致三维模拟的实施存在困难。文中探索以道路为参考依据,利用地下管线的点位探测数据进行概略内插计算,以最小代价实现小区域范围的地下管线、道路甚至地面构筑物的三维模拟显示和数据集成。

Because three-dimensional simulation is an intuitionistic style of underpipe data, it becomes a necessary tool of underpipe information system. But the excellent vision depends on high cost DEM data. Discussion is made on how to realize a small area three-dimensional simulation and data integration for underpipe, road and ground establishment. The method is calculated by using underpipe explored point data.
