基于ARM的视频监控系统设计

ARM-Based Video Surveillance System Design

视频监控是现代安全的重要手段,传统的视频监控系统存在结构复杂、稳定性差、传输距离短等问题。本文采用ARM9微处理器S3C2440和嵌入式操作系统作为平台,通过移植linux内核到开发板,简化驱动程序和应用程序,在内核现有的摄像头驱动的基础上移植摄像头驱动程序,使用QT技术设计了一个嵌入式视频监控系统。实验结果表明,该系统实现了四个不同方向的视频监控,也验证了本文提出的视频监控设计方案及技术是正确可行的。

Video surveillance is an important method of modem security. The traditional video surveillance system has many problems, such as complex structure, poor stability, and short transmission distance and so on. The paper uses the ARM9 $3C2440 microprocessor and embedded operating system as the platform, and ports the Linux kernel to the development board to simplify the driver program and application program. The paper transpla nts the camera driver based on the existing driver in the kernel, and by using QT technology designs an embedded video monitoring system. The experimental results show that the system achieves four different directions of video surveillance, and prove that the design scheme and the technique proposed in this paper are correct and feasible.
