摘　　要：随着机器视觉的发展,针对目前的嵌入式设备对视频数据采集速度慢、分辨率低以及实时性不高的问题,提出一种基于Xilinx ZYNQ芯片的实时视频采集系统,该芯片采用ARM+FPGA的异构设计,利用该特性搭建软硬件协同设计的视频处理平台。FPGA端实现图像的预处理,ARM端实现对外设的配置,图像传输则利用AXI总线通过HP端口将数据高速存储到DDR中,最后利用HDMI端口对视频进行显示。通过利用FPGA的并行性和芯片中的高性能总线在保证系统低功耗的同时相比于一般的嵌入式设备具有更快的处理速度和更大的带宽以及实时性。为分布式部署监控系统以及实现更复杂的图像处理算法提供可靠稳定的平台。With the development of machine vision,a real-time video acquisition system based on Xilinx ZYNQ chip is proposed for the problems of slow video data acquisition speed,low resolution and low real-time performance of current embedded devices.The heterogeneous design of FPGA+ARM uses this feature to build a video processing platform de-signed by hardware and software.The FPGA side realizes the image preprocessing,the ARM side realizes the configura-tion of the peripherals,and the image transmission uses the AXI bus to store the data in the DDR at high speed through the HP port,and finally uses the HDMI port to display the video.By using the parallelism of FPGA and the high-per-formance bus in the chip,the system has lower power consumption and faster processing speed,larger bandwidth,and real-time performance compared to general embedded devices.It provides a reliable and stable platform for distributed deployment of monitoring systems and implementation of more complex image processing algorithms.
