摘　　要：针对铁路客运站视频监控系统中摄像机布设和调整缺乏科学有效的评价方法和缺少获取三维动态指标的计算机工具这两大问题,本文提出了三维空间下的视频监控布局方案评价指标体系,建立了客运站数字孪生底座构建方法和数字孪生视频监控摄像机仿真方法,基于Unity 3D引擎完成了数字孪生铁路客运站视频监控仿真评价功能模块开发,最后以上海局管内某客运站为实例开发了视频监控仿真评价系统,完成了对该站视频监控布局方案的对比评价,验证了方法的可行性。结果表明:基于数字孪生的铁路客运站视频监控仿真评价方法能够准确评估客运站视频监控点位布局的合理性,为客运站评估和优化视频监控点位布局以及保障安全营运提供技术和工具。Aiming at the two major problems of the lack of scientific and effective evaluation methods for camera layout and adjustment in the video surveillance system of railway passenger stations and the lack of computer tools for obtaining three-dimensional dynamic indicators,an evaluation index system for video surveillance layout schemes in three-dimensional space is proposed,and a digital twin base construction method and a digital twin video surveillance camera simulation method specifically for passenger stations are established.Based on the Unity 3D engine,the video surveillance simulation evaluation function module of the digital twin railway passenger station was developed.Finally,a video surveillance simulation evaluation system was developed with a passenger station in Shanghai as an example.The comparative evaluation of the video surveillance layout scheme of the station was completed,and the feasibility of the method was verified.The results show that the video surveillance simulation evaluation method of railway passenger station based on digital twin can accurately evaluate the rationality of the layout of video monitoring points in passenger stations,and provide technology and tools for evaluating and optimizing the layout of video monitoring points in passenger stations and ensuring safe operation.
