摘　　要：针对大量古建筑现存图件资料缺乏,且传统测量手段获取古建筑信息时所表现的效率低下问题,提出了用于实现古建筑信息模型重构的BIM-LiDAR集成技术。该技术的实现流程包括原始点云数据获取、点云数据预处理、二维线化图件制作、古建筑各构件“族”库建立、三维模型构建等步骤。并将该技术用于西藏拉萨代表性建筑罗布林卡5号门楼模型的重构,应用结果显示用该技术生成重构模型的误差在10 mm左右,完全符合精度要求,验证了该技术用于模型重构的可行性,可为类似工程提供参考。In view of the fact of lacking existing drawings and data of a large number of ancient buildings,and the inefficiency of traditional measuring methods in obtaining ancient building information,this paper proposes a BIM-LiDAR integration technology for reconstructing ancient building information models.The implementation process of this technology includes the steps of acquiring original point cloud data,preprocessing point cloud data,making two-dimensional linearized drawings,establishing the library of each component family of ancient buildings,and building three-dimensional models.Finally,the technology was used to reconstruct the model of Gatehouse 5 of Norbulingka,a typical building in Lhasa,Tibet.The application results show that the error of the reconstructed model generated with this technology is about 10 mm,which fully meets the accuracy requirements,verifies the feasibility of this technology for model reconstruction,and can provide reference for similar projects.
