摘　　要：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(building 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。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 performs 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.
