无人机摄影三维建模在历史建筑中的应用

Application of 3D Modeling of Uav Photography in Historical Buildings

历史建筑是一座城市的人文记忆,保护和挖掘历史建筑的内涵是城市精神延续的基础,对优秀历史建筑进行勘察修缮保护意义重大。在优秀历史建筑保护工作中,一个相当重要的环节就是对勘察数据信息的保存,传统的勘察方法存在数据无法可视化或者可视信息碎片化等一系列问题,保存的信息往往只是零星碎片,无法迅速获得直观全面的感受。而无人机摄影三维建模技术,由于具有自动化、效率高和模型逼真的优点,被逐步应用于智慧城市的建设中。文章以某优秀历史建筑为研究案例,基于多旋翼单镜头无人机模拟倾斜摄影,采用网带式航线进行拍摄,并使用Context Capture软件对影像数据进行建模处理,得到该优秀历史建筑的实景三维数字模型。该项技术的运用为今后优秀历史建筑的快速数字化存档提供一定参考。

It is the continuation of a city’s history and the preservation of its architectural spirit.It is of great significance to investigate,repair and protect excellent historical buildings.A very important link in the protection of excellent historical buildings is the preservation of survey data and information.Traditional survey methods have some problems,such as data cannot be visualized or visual information is fragmented.The saved information is often only sporadic and fragmented,which cannot make people quickly get an intuitive and comprehensive feeling.Due to the advantages of automation,high efficiency and realistic model,the three-dimensional modeling technology of UAV photography has been gradually applied to the construction of smart city.This paper takes an excellent historical building as a research case,based on multi rotor single lens UAV simulated tilt photography,uses mesh belt route for shooting,and uses context capture software to model and process the image data,the real 3D digital model of the excellent historical building is obtained.It provides a reference for the rapid digital archiving of excellent historical buildings in the future.
