摘要
针对激光雷达及倾斜摄影技术应用于历史建筑数字化保护过程中,获得的三维点云数据存在缺失、疏密不一和数据异常,且点云拟合生成的三维模型不可拆解等问题,提出了一种基于知识图谱建构及推理技术的历史建筑信息模型自动生成方法。先根据建筑营造技艺规则,建构建筑各构件自身及相互间的数据结构和空间拓扑关系知识图谱,再结合已知点云数据科学推理缺失构件信息,最后补全构件参数,完成模型自动化搭建。对比目前主流的基于点云数据逆向人工建模方法,该方法建模速度更快、模型构件可拆解、参数信息更完整。通过山西晋祠圣母殿大木作实验结果表明,该方法获得的参数化模型能够全面真实展示建筑的结构信息和传统营造技艺,为历史建筑数字化保护提供重要的技术手段。
This paper proposes an automatic generation method for historical building information models based on knowledge graph construction and inference technology,which addresses the issues of missing,inconsistent density,and abnormal data in the application of LiDAR and oblique photography technology in the digital protection process of historical buildings.Additionally,the 3D point cloud data obtained through point cloud fitting cannot be disassembled.Firstly,according to the rules of architectural construction techniques,construct a knowledge graph of the data structures and spatial topological relationships of each component of the building itself and between them.Then,combined with known point cloud data,scientifically infer missing component information.Finally,complete the component parameters and complete the automated model construction.Compared to the current mainstream reverse manual modeling methods based on point cloud data,this method has faster modeling speed,detachable model components,and more complete parameter information.The experimental results of the structural carpentry of the Sheng Mu Miao at Shanxi province Jinci Temple show that the parameterized model obtained by this method can comprehensively and realistically display the structural information and traditional construction techniques of the building,providing an important technical means for the digital protection of historical buildings.
