基于数字孪生技术的智慧校园时空底座建设

Construction of Spatio-Temporal Foundation for Smart Campus Based on Digital Twin

物联网、大数据、人工智能技术的发展孕育了数字孪生技术。三维实景校园时空底座是应用数字孪生技术建设智慧校园的基础。通过倾斜摄影技术、三维激光扫描技术与人工建模技术相结合的三维校园时空底座制作方法,能够补充倾斜摄影在建筑底部及内部等遮挡密集区域的信息,在提高三维校园模型精度的同时,实现多源数据的融合三维实景建模。通过不同来源、不同格式数据的优势互补,更好地建设校园时空三维底座,为数字孪生校园的建设提供支撑。

The development of the internet of things,big data and artificial intelligence have produced digital twin.The spatiotemporal foundation for 3D real smart campus is the basis of digital twin campus.By combining oblique photography,threedimensional laser scanning and artificial modeling technology,the 3D campus spatio-temporal foundation production method can supplement the information of oblique photography in the obscured dense areas such as the bottom and interior of buildings.Not only will it improve accuracy of 3D campus model,but also will accomplish dominance complement of data in different formats from different sources.By combining the advantages of data from different sources and formats,the spatio-temporal foundation will be constructed better,so that support the construction of digital twin campus.
