前言随着轨道安防系统逐步发展和高清监控技术的完善,目前轨道视频监控正处在由标清“看得见”到高清“看得清”的发展历程中。轨道监控高清化带来了实实在在的画面革新,高清摄像机采集的图像细节更多,对监控对象局部特征的展现更为细致。高清监控系统给视频智能分析应用提供了坚实的基础。现阶段,视频智能分析在轨道交通行业中主要应用包含三大类:行为分析即拥挤侦测、徘徊侦测、逆向侦测等;特征识别即人脸识别系统等;图像
Preface With the gradual development of orbital security system and the improvement of high-definition monitoring technology, the current orbital video surveillance is in the course of development from standard definition “visible” to “high definition” “clear”. High-definition orbit monitoring brings a real picture of innovation, high-definition camera capture more details of the image, the monitoring of the local characteristics of the show more detailed. HD surveillance system for video intelligent analysis and application provides a solid foundation. At this stage, video intelligent analysis in the rail transit industry, the main application includes three categories: behavior analysis that congestion detection, wandering detection, reverse detection, etc .; feature recognition that face recognition system; image
