地下隧道三维模型构建方法实践与分析

Practice and Analysis of Three-Dimensional Model Construction Method of Underground Tunnels

在智慧城市理念中,针对城市基础设施中地下设施可视化问题,文章以新乡市地下隧道为例,利用三款三维建模软件、数字近摄影测量方法和非量测型智能手机相机等设备,对所采集到的地下隧道影像数据构建地下隧道的三维模型。研究表明,智能手机采集影像可高效、高质量地构建地下隧道三维模型,对比可以得到三款建模软件的建模效果,对该领域的后续研究具有一定参考意义。

In the concept of smart city,aiming at the visualization of underground facilities in urban infrastructure,taking the underground tunnel in Xinxiang city as an example,three three-dimensional modeling software,digital near photogrammetry and non-topographic smart phone camera are used to construct three-dimensional model of underground tunnel from the collected image data of underground tunnel.The research shows that the images collected by smart phones can construct the three-dimensional model of underground tunnel with high efficiency and quality,and the modeling effect of the three modeling software can be obtained by comparison.In addition,it has certain reference significance for the follow-up research in this field.
