【摘要】 行人交通是我国城市居民出行的主要交通方式,而行人交通的视频检测技术对于智能交通系统的发展与应用具有重要意义.通过对行人检测和分析确定行人的运动轨迹,提取行人交通参数,为交通规划、管理与控制提供科学的数据.首先回顾行人交通视频检测技术的发展历程,综述研究的方法、技术和主要成果;其次,从行人交通系统的一般处理框架——行人检测、识别、跟踪和交通参数的提取,分层次回顾低级、中级和高级各处理阶段的发展水平;重点阐述各处理阶段的现有技术和方法,并将每阶段相应地划分为不同方法子类加以讨论;最后,分析行人检测研究的技术难点及未来的发展趋势.更多还原

【Abstract】 Pedestrian traffic is the major trip mode of Chinese urban residents.Being the important part of intelligent transportation system,pedestrian traffic data collection method based on video image processing is the basis of traffic planning,traffic management and traffic control by detecting pedestrian,analyzing motion trajectory and extracting traffic parameter.This paper reviews the development of pedestrian traffic collection method technique and describes four steps studied intensively in the past work including pedestrian detection,recognition,tracking,and traffic parameter extraction.Finally,the recent problems and prospect in this area are also provided.更多还原
