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。 Aiming at the moving target in video surveillance, this paper introduces the idea of ​​autonomous tracking and designs a real-time tracking and monitoring system of moving target based on DSP. The system takes TI’s DSPTMS320DM642 as the core, uses the improved differential algorithm combined with binary morphological processing for motion detection, and obtains the rotational vector of the PTZ by speed normalization, which is applied to the PTZ system of variable speed, Target self-stable tracking. Experiments show that the system has achieved a good tracking effect to ensure the autonomy of target tracking, accuracy and real-time.
