Embedded Intelligent Monitoring System Based on DaVinci

摘要:

对嵌入式智能监控系统进行研究,提出了一种基于达芬奇技术的嵌入式智能监控系统设计方案;该系统对运动目标检测方法进行分析,采用基于图像序列的背景减除法检测入侵目标,用中值法对背景进行动态更新维护,并在构建的基于DaVinci技术的硬件平台上实现了入侵报警算法；实验表明,采用中值法进行动态背景维护,能较好适应外部环境的变化,在检测到警戒区域运动入侵目标的同时,获得入侵目标的方向信息,并在0.5 s内发出预警信号,满足系统实时性的要求。

Abstract:

This paper discuss embedded intelligent monitoring system based on DaVinci. This scheme analyse the technique about moving detect invasion target using background subtraction of image sequence, apply median method to maintain background in order to have great adaptability and realize warning algorithm based on DaVinci hardware platform. The experimental results indicate that using median method can adapt to the environmental change, detect invasion target and acquire direction of motion, meanwhile, send out warning signal within 0.5 seconds, therefore, fulfill system requirement of real-time.
