提出了联合室内空间语义的室内空间运动剖分算法,采用形态学操作提取墙中线,并对墙体对象进行融合优化与拓扑重构,实现了基于激光点云的建筑信息模型(build-ing information modeling,BIM)实体墙对象几何和拓扑重建.以某综合楼三维点云为实验数据重建BIM实体墙模型,验证了提出方法的可靠性.
Geometry and Topology Reconstruction Method for BIM Wall Objects
This study proposes a BIM solid wall geometry and topology modeling method based on laser point cloud.First,it applies kinetic space partition algorithm which com-bines Semantic information of indoor space.Then it uses morphological operator to extract the wall centerline,and per-forms fusion and topology reconstruction of wall objects.The experiments are tested on point cloud of a complex building and BIM solid wall model are reconstructed,which verifies the reliability of the proposed method.
