多传感器智能视频监控系统关键技术研究

摘要

To improve video surveillance system's quick self-traceability and tracking precision of fast moving targets,this paper presents an intelligent video surveillance solution,which,by adopting sound source localization,realizes quick positioning of dynamic targets, and detects moving objects in the 3 adjacent frame-difference method before using the obtained centroid parameters as control signal for PTZ control system to drive the PTZ and camera to trace moving targets on a real-time basis.Experiment and simulation results show that the control scheme can completely satisfy surveillance requirements.%为了提高视频监控系统对高速运动目标的自主快速跟踪能力和跟踪精度，提出了一种智能视频监控方案。采用声源定位技术实现对动态目标的快速定位，并应用相邻三帧差分法实现运动目标的提取，然后将提取出的动态目标的形心参数作为云台控制系统的控制信号，以驱动云台带动摄像机实现对运动目标的实时跟踪监控。实验及仿真结果表明，所采用的方案完全能够满足监控要求。
