摘　　要：为保证火灾情况下,大型室内空间受困人员可以及时获取最佳的空间疏散路径,研究特征标记下大型室内空间疏散最优路径三维虚拟搜索模型。利用三维激光扫描技术获取大型室内建筑的点云数据,标记、提取点云数据特征信息,构建大型室内空间三维模型;以建筑的建设空间数据为依据,生成大型室内疏散路径模型;构建疏散最优路径虚拟搜索目标函数,采用改进麻雀搜索算法进行求解,获取最优路径。测试结果表明:应用所提出的模型后,疏散路径长度为52.9 m,路径拐点数量为10个,达到出口的时间为11.5 s,可以有效搜索最优的疏散路径。To ensure that trapped individuals in large indoor spaces can timely obtain the optimal evacuation path in case of fire,a 3D virtual search model for the optimal evacuation path of large indoor spaces under feature labeling is studied.The 3D laser scanning technology is utilized to obtain point cloud data of large indoor buildings,label and extract point cloud data feature information to construct a 3D model of large indoor spaces.A large-scale indoor evacuation path model is generated based on the construction space data of the building and a virtual search objective function is constructed for the optimal evacuation path with an improved sparrow search algorithm,to obtain the optimal path search results.The test results show that after applying the proposed model,the evacuation path length is 52.9 m,the number of path inflection points is 10,and the time to reach the exit is 11.5 s,which can effectively search for the optimal evacuation path.
