基于激光三维扫描建筑空间结构虚拟重建系统

Virtual reconstruction system based on laser three-dimensional scanning building space structure

当前方法在重建建筑空间结构时由于缺少单片测图,导致三维建模结果与实际结果拟合度低、建模过程耗时较长。提出基于激光三维扫描的建筑空间结构虚拟重建系统。根据单片测图和三维激光扫描技术对重建系统进行总体设计,详细分析经激光三维扫描获取建筑空间结构数据的流程、预处理以及配准方法,利用三角网格对建筑空间结构模型进行三维重建,并提供建筑空间结构的外廓采集工具以及交互编辑环境给作业人员,实现对建筑空间结构的虚拟重建。实验结果表明,利用该系统进行建筑空间结构虚拟重建,三维建模结果与实际结果的拟合度较高,且建模耗时较短,应用性更强。

The current method in reconstructing the spatial structure of the building is due to the lack of single-chip mapping,resulting in low fitting of the 3D modeling results with the actual results,and the modeling process takes a long time.A virtual reconstruction system for building space structure based on laser 3D scanning is proposed.Ac-cording to the single-chip mapping and 3D laser scanning technology,the overall design of the reconstruction system is carried out.The process,pre-processing and registration method of obtaining the spatial structure data of the building by laser three-dimensional scanning are analyzed in detail.The three-dimensional reconstruction of the architectural space structure model is carried out by using the triangular mesh.And provide the external space acquisition tool of the building space structure and the interactive editing environment to the operator to realize the virtual reconstruction of the building space structure.The experimental results show that the virtual reconstruction of the building space struc-ture is carried out by using the system.The fitting of the 3D modeling results with the actual results is high,and the modeling takes less time and is more applicable.
