三维激光扫描技术在历史建筑测绘中的应用——以闽清县历史建筑测绘建档项目为例

Application of 3D Laser scanning technology in surveying and mapping of historical buildings——Taking the historical building mapping and filing Project in Minqing County as an example

历史建筑作为城市的文脉,承载着一座城市的历史,受各种因素影响遭受不断的侵蚀甚至灭失,其保护形势越来越严峻。文章以闽清县历史建筑保护测绘为例,采用三维激光扫描技术,结合无人机倾斜摄影技术,对历史建筑真彩色三维点云模型建设进行了探索研究,为历史建筑的测绘资料建档和文物保护工作积累了宝贵的技术经验。结语对该技术进行了总结分析,认为三维激光扫描技术不仅能大幅提升工作效率和测量成果精度,还可实现历史建筑三维可视化,具有广阔的应用前景。

As the context of a city,historical buildings carry the history of a city.Affected by various factors,they suffer continuous erosion and even loss,and their protection situation is becoming more and more serious.Taking the protection surveying and mapping of historical buildings in Minqing County as an example,this paper explores and studies the construction of true color three-dimensional point cloud model of historical buildings by using three-dimensional laser scanning technology and UAV tilt photography technology,which has accumulated valuable technical experience for the filing of Surveying and mapping data of historical buildings and the protection of cultural relics.The conclusion summarizes and analyzes this technology,and holds that the 3D laser scanning technology can not only greatly improve the work efficiency and measurement accuracy,but also realize the three-dimensional visualization of historical buildings,which has broad application prospects.
