基于DM642的运动目标实时跟踪监控系统的设计

针对视频监控中的运动目标,引入自主跟踪思想,设计了一种基于DSP的运动目标实时跟踪监控系统。系统以TI公司的DSPTMS320DM642为核心,采用改进的差分算法辅以二值化形态学处理进行运动检测,并通过速度归一化求取云台转动矢量,应用于变速云台系统,实现了对运动目标的自主稳定跟踪。实验证明,系统取得了良好的跟踪效果,保证了目标跟踪的自主性、准确性和实时性。

Design of surveillance system for real-time tracking of moving object based on DM642

A surveillance system for real-time tracking of moving object with DM642 is designed based on the idea of autonomous tracking.With DSP TMS320DM642 as its core,the system adopts the algorithm of improved difference and binary morphology to detect moving object firstly,then the shift vector of PTZ(Pan/Tilt/Zoom) is calculated through the speed normalization.The autonomous and stably tracking to the moving object is achieved on the variable PTZ system.Experimental results show that the designed system can track the real-time moving object automatically and accurately.
