基于BIM技术及三维激光扫描技术的古建筑修复保护研究

Research on the restoration and protection of ancient buildings based on bim technology and three-dimensional laser scanning technology

将三维激光扫描技术与BIM技术进行衔接,应用于古建筑的保护与修复,能发挥两种技术的优势。先通过三维激光扫描技术准确获取古建筑的几何信息,生成点云模型,再基于点云模型,建立BIM模型,从而实现文物古建筑修复的正向设计,为修复施工、古建筑维护、信息存档提供技术支持。

The combination of three-dimensional laser scanning technology and BIM technology can bring the advantages of the two technologies into full play when applied to the protection and restoration of ancient buildings. Firstly, the geometric information of ancient buildings is acquired accurately by three-dimensional laser scanning technology, and point cloud model is generated. Then, based on point cloud model, BIM model is established, which realizes the forward design of the restoration of cultural relics and ancient buildings, and provides technical support for restoration construction, maintenance of ancient buildings and information archiving.
