摘要
城镇排水管网是城市安全稳定运行的基础,而传统二维图形技术无法呈现出地下管线空间分布的复杂情况.基于Cesium提出一种利用排水管网DWG数据自动构建三维地下管网3DTiles模型的建模方法.具体步骤是数据预处理去除错误数据、制作管网模型、数据坐标转换,数据分幅提高模型生成效率,软件开发自动化生成模型中间文件,模型切片最终可视化展示.结果表明,DWG数据能快速生成3DTiles模型,实现良好的地下三维模型可视化展示,为后续Cesium地下空间相关研究工作提供技术支持和方法参考.
Abstract
The urban drainage pipe network serves as the cornerstone for ensuring the safe and stable functioning of a city. However,con-ventional two-dimensional graphic techniques fall short in capturing the intricate spatial distribution of underground pipelines. In light of this,a novel modeling approach leveraging Cesium is proposed to automatically generate three-dimensional 3DTiles models of underground pipe networks using DWG data. The methodology encompasses several key steps,including meticulous data preprocessing to eliminate erroneous en-tries,creation of the pipe network model,data coordinate transformation,data segmentation to enhance model generation efficiency,software de-velopment enabling automated generation of intermediate model files,and model slicing for ultimate visualization. The outcomes of the study demonstrate the rapid generation of 3DTiles models from DWG data,facilitating the effective visualization of intricate underground three-di-mensional structures. This breakthrough offers valuable technical support and serves as a methodological reference for subsequent research on Cesium-related investigations in the field of underground spaces.
