Research on Field-of-View Model of Railway Video Surveillance System Oriented to BIM Simulation
During the design of front-end acquisition points of railway video surveillance system,it often relies on the engineering experience of designers to judge whether the layout scheme of acquisition points is reasonable.It lacks quantitative and intuitive judgment criteria and is difficult to accurately evaluate the actual coverage effect of acquisition points.Starting from the basic field-of-view coverage model,in combination with the characteristics of railway video surveillance system,aiming at different scenes and coverage targets,the application scenarios of railway field-of-view models are divided into conventional video coverage scenarios and coverage scenarios with target identification requirements.This paper proposes a corresponding mathematical model of field-of-view coverage to provide a basis for establishing the field-of-view of video surveillance system oriented to BIM field-of-view coverage simulation.The BIM field-of-view model drive of video surveillance acquisition points is realized by using the input parameters and the target value parameters required by the simulation model,thus enabling flexible adjustment and optimization of field-of-view.
