基于无人机的市政道路三维实景建模研究及应用

Research and Application of 3D Real Scene Modeling of Municipal Road Based on UAV

随着社会发展的不断加快,道路建设的需求量也在逐年上涨,市政道路作为建设项目当中最为重要的一环,其施工质量与效率对市政道路建设质量有着显著影响,而市政项目建模技术较少应用于项目过程管理。因此本文建立基于无人机的市政道路三维实景建模系统,在公路改建工程项目中投入使用,实验结果显示:(1)基于无人机的市政道路三维实景建模技术整体误差处于-0.8~+0.8 m之间,具有较好的精度以及适应性;(2)该技术以较低的操作成本和较为快捷的途径实现了市政道路工程场景的还原重建,为智慧工地发展提供了坚实的基础。

With the continuous acceleration of social development,the demand for road construction is also increasing year by year.As the most important part of the construction project,the construction quality and efficiency of municipal roads has a significant impact on the quality of municipal road construction,but municipal project modeling technology is rarely used in project process management.At present,this technology is mainly invested in the preliminary investigation stage of construction projects,and is less used in project process management.Therefore,this paper establishes the 3D real scene modeling system for municipal roads based on UAVs in the project road reconstruction The project was put into use,and the results showed:(1)The overall error of the UAV-based 3D real scene modeling technology is basically between-0.8~+0.8 m,with good accuracy and adaptability;(2)The technology is based on lower operating costs and faster ways have realized the restoration and reconstruction of municipal road earthwork scenes,providing a solid foundation for the development of smart construction sites.
