基于DM8168的哨位安全智能视频分析系统

设计了一种基于DM8168嵌入式平台的多路视频输入的哨位安全智能视频分析系统,并采用灰度与光流双模型的背景建模与更新,实现了对人员闯入、遗留物检测,并对哨兵异常行为识别;试验表明:系统的检测精度高,虚警率较低,系统性能稳定、实时性好;本系统在哨位安防监控中得到了很好的应用,有效提升了哨位对安全威胁的预警能力,满足武警、公安部队哨位智能设备的应用需求.

Intelligent Video Analysis System Based on DM8168 Security Guard

We designed a kind of intelligent video analysis system sentinel security based on DM8168 embedded platform for multi-channel video input, and used background modeling and updating method of gray model and optical flow modeling of double background to realize the detection of personnel, the sentry and so on.Experiments show that the system has high detection accuracy, low false alarm rate, stable performance and good real-time performance.The system has a good application in sentinel security monitoring, and it improves the early warning ability of security threats sentinel to meet the application requirements of intelligent equipment of security forces and armed police sentry.
