基于三维激光扫描技术生产古建筑BIM的研究

Research on the Production of BIM for Ancient Buildings Based on 3D Laser Scanning Technology

传统测绘技术在古建筑测绘中存在细节丢失、效率低下、易对古建筑造成破坏等缺点。该文将三维激光扫描技术与BIM技术进行结合,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,为古建筑的保护与发展提供技术支持。研究表明,基于三维激光扫描技术生产古建筑BIM在古建筑保护中具有极强的研究价值。

Traditional surveying and mapping techniques have some disadvantages in the surveying and mapping of ancient buildings,such as loss of details,low efficiency,easy damage to ancient buildings and so on.The article combines 3D laser scanning technology with BIM technology.First,accurately obtain geometric information of ancient buildings through 3D laser scanning technology,generate point cloud models,and then build BIM models based on point cloud models to provide technology for the protection and development of ancient buildings support.Research shows that the production of BIM of ancient buildings based on 3D laser scanning technology has strong research value in ancient building protection.
