视频事件检测器的发展综述

Overview of the Development of Video Incident Detector

为充分把握视频事件检测器的市场需求,准确预测其发展趋势,回顾我国智能交通系统行业的整体发展历程,分析视频事件检测器各发展阶段的行业需求和产品应用情况,重点阐述目前市场上主流的人工智能(Artificial Intelligence,AI)视频事件检测器的发展前景。通过总结发现:视频事件检测器从出现至今主要历经了标清视频事件检测器、高清视频事件检测器、云台式视频事件检测器和AI视频事件检测器等4个阶段;虽然在每个发展阶段视频事件检测器的检测效果和识别效率等性能都有所提升,但随着应用需求的不断提升,其面临的技术和应用瓶颈会日益明显;随着AI和云计算等技术的不断发展,利用信息化手段动态、实时地感知交通事件和交通流状态,主动预测交通状况,将是视频事件检测器未来的主要发展趋势之一。

This paper studies the demands of traffic management industry for video incident detectors and the application of the detectors in traffic engineering projects at development stages and highlights the developments of mainstream AI(Artificial Intelligence) video incident detectors in traffic engineering market.The video incident detector has developed in four stages,from standard definition video incident detector,high-definition video incident detector,cloud desktop video incident detector to AI video incident detector.The detection effectiveness and recognition efficiency and other function-alities have been improved through the stages,but with the ever-escalating requirements,the technical and application bottleneck is gradually emerging.With the development of AI and cloud computing technology,deep involvement of AI technology will be the main development trend of video incident detector and they will develop the capability to dynamically perceive the status of traffic incidents and traffic flow in real time and to actively predict traffic safety incidents and traffic conditions.
