摘　　要：Revit是在我国应用的主流BIM软件之一,基于Revit建立铁路站房三维场景,进行摄像头建模,根据摄像头成像参数对监控覆盖区域进行模拟,实现铁路站房摄像头监控覆盖区域、重叠覆盖区域及盲区的监控和标记,评估监控区域覆盖效果。通过对摄像头的数量、类型、安装位置、角度进行调整,优化视频监控目标清晰度、覆盖效果,提高摄像头布置的准确性,减少摄像头数量。基于BIM的视场仿真技术除了可应用于铁路站房外,还可用于飞机场、港口、地铁站、汽车站、电影院等安全要求高的大型公共场所。3D scene of railway station buildings is established based on Revit software,camera modeling is carried out and the monitoring coverage area is simulated according to camera imaging parameters to realize the monitoring and marking of cameras in the monitoring,overlapping and blind areas of railway station buildings and evaluate the coverage effect of the monitored area.The number,type,installation position and angle of cameras are adjusted to optimize the monitoring clarity and coverage effect of the video monitoring area,improve the accuracy of camera layout,and reduce the number of cameras.In addition to railway station buildings,BIM-based analog simulation technology of the field of view can also be applied to airports,ports,metro stations,bus stations,cinemas and other large-scale public buildings with high safety requirements.
