无人机倾斜摄影航测技术与BIM结合在智慧工地系统中的应用

Application of unmanned aerial vehicle tilt photography aerial survey technology combined with BIM in smart site system

智慧工地系统的建设,着力解决当前工程建设信息化水平低的突出问题,利用物联网、互联网、BIM技术、无人机倾斜摄影技术等信息化手段,实现对工程建设领域相关过程的全方位监测管理。将无人机倾斜摄影航测采集的数据信息与BIM结合生成三维建筑模型,构建信息共享、集成应用的三维数据信息系统。将该技术应用于建筑工程项目管理中,与传统二维设计相比,利用BIM模型可实现碰撞检查、施工进度模拟、工程量统计、日照分析和质量管理等,提高了工程管理的信息化水平。

In view of the low level of informatization in project management of engineering construction,this paper uses the Internet of things,Internet,BIM technology,inclined uav photography technology and other information means to realize the visual supervision of engineering construction projects.Abundant image information of the construction site can be collected by using uav tilt photography technology to establish high-quality 3D GIS model,which can be imported into BIM software to generate 3D building model and build a 3D data information system with information sharing and integrated application.Compared with traditional 2D design,BIM model is used to realize collision inspection,construction progress simulation,quantity statistics,sunshine analysis and quality management,which improves the informatization level of project management.
