Abstract: This paper researches on the integration method of railway integrated video monitoring system and BIM to improve the user interaction and data application capability. The advantages of applying BIM to build 3D virtual space and associate the monitoring scene data are analyzed, the system integration is realized by building the BIM integration application function module, the data interaction is completed by using the video interface, BIM preprocessing and data sharing, and data integration is performed through 3D virtual space construction, camera range virtualization, and monitoring object data association, to support the realization of monitoring capability simulation, object association call, data overlay display and other application functions, and provide 3D visualization and augmented reality interaction capabilities. By integrating the railway integrated video monitoring system and BIM to form a digital twin system, it will help improve the railway ubiquitous perception ability and have a broad application prospect in the construction of intelligent high-speed railway.
