说明：  选用ZYNQ SoC作为智能相机系统的硬件处理平台，依据系统设计需求，将系统整体功能结构的开发划分到用户空间、内核空间、底层硬件三个层面。在硬件层，对系统硬件功能进行了模块化设计，分别对基于USB和OV7725的双通道图像采集模块、HDMI显示模块进行开发。(Zynq SOC is selected as the hardware processing platform of the intelligent camera system. According to the system design requirements, the development of the overall functional structure of the system is divided into three levels: user space, kernel space and bottom hardware. In the hardware layer, the hardware functions of the system are modularized, and the dual channel image acquisition module and HDMI display module based on USB and ov7725 are developed respectively.)
