1、随着人们对安全意识的日益重视与提高,视频监控系统在安防监控、工业控制、交通监控等领域屮已经有了广泛的应用。基于DSP的视频监控能够提高视频传输的可靠性和传输速度,减小体积和重量,并能降低功耗和成本,具有较强的环境适应性。因此从经济和实用的角度来讲,基TDSP的视频监控系统具有很好的发展前景。木文提出了一种视频监控系统硬件平台的设计方案,硬件平台主要包括DSP主控系统硬件平台、监控云台、摄像机和显示器。首先对视频监控系统研究的目的和难点进行分析,并对视频信号做了简要的介绍。在此基础上根据系统设计的要求,给出系统总体结构设
2、计方案。随后,根据视频监控系统在设计中对实时性和智能化的要求,结合设计中的难点,给出了基于TMS320DM642的视频监控系统的硬件设计方案,并给出了各硬件模块换件电路连接图。根据硬件设计方案,介绍了基于硬件平台的目标跟踪的具体实现步骤,提岀了日标捕捉、口标跟踪以及云台控制的软件设计方案。最后,结合在本系统设计过程中的经历,总结开发过程中的经验和不足。关键词:DSP,视频监控,运动检测,H标跟踪AbstractAlongwithmoreattentionandimprovetothesocialsecurityawar
