智能视频分析技术在地铁站客流监测中的应用研究

Application of intelligent video analysis technology in passenger flow monitoring of metro station

由于地铁的客流具有时空不均衡的特点,大客流车站在客流高峰时段会出现站内密度过大与乘客滞留等问题。为提高地铁的运营效率与保障乘客安全,需要对地铁站内的客流进行全面监测与量化分析。文章在总结地铁站客流监测现状的基础上,对智能视频分析技术在客流监测中的应用进行研究。以北京市西二旗地铁站为研究对象,首先对客流监测系统的功能需求进行针对性分析,其次对基于智能视频分析技术的客流监测系统的总体框架、硬件组成与网络拓扑以及所采用的算法分别进行说明,最后对所搭建的西二旗地铁站客流监测系统的平台界面进行简要描述。初步测试结果表明,本系统可以有效提高客流统计的全面性和安全防范的效能,从而证明智能视频分析技术在地铁站客流监测中的应用以及推广价值。

Due to the space-time imbalance characteristic of the metro passenger flow,issues such as excessive density and passenger retention appear in metro stations with large passenger flows during peak hours.To improve the operational efficiency of the metro system and ensure the safety of passengers,it is necessary to comprehensively monitor and quantitatively analyze the passenger flows in such metro stations.Based on the summary of the current situation of passenger flow monitoring in metro station,this paper studies the application of intelligent video analysis technology in the passenger flow monitoring.The Xi’erqi station of Beijing metro was taken as the research object.First,the functional requirements of the passenger flow monitoring system are analyzed.Then the overall framework,hardware composition,network topology and algorithm of the passenger flow monitoring system based on the intelligent video analysis technology are illustrated.Finally,the platform interface of the passenger flow monitoring system of the Xi’erqi station is briefly described.The preliminary test results show that the proposed system can effectively improve the comprehensiveness of passenger flow statistics and the efficiency of safety precautions,which proves the value of application and promotion of intelligent video analysis technology in the passenger flow monitoring of the metro station.
