基于嵌入式平台的网络视频监控系统应用

Application of network video monitoring system based on embedded platform

针对重要工业场所周边、家居安防等场景下的自动检测入侵目标、智能控制云台跟踪目标运动轨迹、远程终端访问的监控需求,设计了一套经济、可靠、智能的网络视频监控系统。该系统选择以达芬奇系列的TMS320DM8168数字媒体处理器为核心的嵌入式平台,通过RTP网络传输协议接收网络摄像头的视频数据,进行处理后再发送到网络,根据系统应用场景优化检测跟踪算法,同时根据算法处理结果驱动网络控制摄像机云台转动,确保精确跟踪监控目标的运动轨迹。该系统解决了在网络监控方面的自动智能检测跟踪问题,并且具有功能扩展性和产品兼容性。研究实验的结果验证了这套系统的可行性。

In view of monitoring requirements of many scenes such as important industrial sites around, home security and so on,which is automatic detection of intrusion target, intelligent PTZ control to tracking the movement of moving objects, remote terminal access, an economical, reliable and intelligent network video surveillance system is designed in this paper. The system chooses the embedded platform based on TMS320DM8168 digital media processor of the Da Vinci series as the core, receives video data of network camera through RTP network transmission protocol and then sends data to the network, optimizes the detection and tracking algorithm according to the system application scenarios, and according to the algorithm processing result controls the camera PTZ through the network, to ensure accurate tracking of the moving trajectory of the monitored target. The system solves the problem of automatic intelligent detection and tracking in network monitoring, and has the functions of scalability and product compatibility. The feasibility of the system is verified by the experimental results.
