摘要
人员疏散时间预估对紧急状况下建筑中发生火灾时所面临的人员疏散问题十分重要。受到建筑中人员所在位置、建筑空间外形尺寸、阻挡物姿态等多个因素影响,人员疏散时间具有不稳定性。基于单目视觉估计的人员快速转移疏散模型在建筑物智能防火中的应用可以有效解决该问题。运用该技术对人员疏散到安全区域的路程进行测距,将测量数据作为参数构建人员紧急疏散时间的预估模型,能够为建筑人员在火灾发生时的紧急疏散预案提供依据。仿真实验表明,人员紧急疏散时间估计模型具有较高的准确性,且具有结构简单、运算量少、立体匹配度高等优点。
Evacuation time forecast is very important in solving the problem of personnel evacuation in an emergency when the building is on fire. Evacuation time is changeable due to the personnel location in the building,the boundary dimension of architectural space, the obstacle posture, and other factors. Based on monocular vision estimation, the application of rapid evacuation model in building's intelligent fireproofing can effectively solve the problem. Using this technology to conduct the distance measurement of the distance for personnel to evacuate to safe region, and with the measurement data as parameter to build the forecast model of personnel emergency evacuation time can provide the basis for construction personnel's emergency evacuation plan when the fire breaks out. The simulation experiments show that the personnel emergency evacuation time estimation model has such advantages as higher accuracy, simple structure, less computation,and higher stereo matching degree and etc..
