摘　　要：提出了一种基于PC机的智能视频监控系统设计方案。将基于直流力矩电动机的三环伺服系统应用于云台控制,有效解决了对高速运动目标的精确实时跟踪问题。系统采用声源定位技术辅助实现对监控目标的快速定位,利用相邻三帧差分法实现了运动目标的提取,并且给出了运动目标的形心计算方法。系统根据运动目标的位置信息,实时控制云台摄像头姿态,使被监控目标始终处于监控画面中央。在MATLAB环境下,对系统各模块进行仿真,结果表明,系统能够实现对高速运动目标的精确跟踪。An intelligent video monitoring system based on PC is proposed. The tricyclic servo system based on DC torque motor is used for PTZ control to improve the traceability and the tracking precision of fast moving targets on its own. Binaural sound localization technology is used to assist the PTZ in turning the camera toward sound sources outside the current field of view. Three-frame-difference method is given to detect the moving object. The target center can be obtained and then the obtained target center parameters are used as the control signals of PTZ control system to drive the camera to trace the moving target. Thus, the moving target can always be in the central position of the view. The simulations are done under the environment of MATLAB. The results show that the system can trace the fast moving target accurately.
