摘要
设计了一种用于物联网智能视频监控终端的嵌入式处理平台。首先根据当前物联网应用中用户对视频监控的需求,结合视频监控硬件的发展现状,建立了采用嵌入式处理平台的智能视频终端模型。然后分析了OMAP系列嵌入式SoC处理器的构成,设计了智能视频监控终端的硬件结构,并基于嵌入式Linux操作系统设计了智能视频终端的嵌入式软件框架。最后给出了系统引导和内核移植的过程,以及视频采集驱动程序的工作流程。
In this paper, the embedded processing platform is designed for video surveillance terminal for the in-ternet of things. The model of smart surveillance terminal is created with current level of the hardware for surveillance and according to customer＇s demand on video monitoring in loT. Then the components of OMAP SoC processer are ana-lyzed to construct the architecture of hardware. Meanwhile, the embedded Linux operating system is used to devise the software framework of smart video terminal. At last, the process of system booting and kernel transferring as well as the device driver of video capture are put forward finally.
