Research of the small-integrated Video Acquisition and Processing System Based on SoC

摘要:

由于传统视频采集和处理系统很难解决小体积、低功耗与高数据带宽和处理速度之间的矛盾，同时针对智能武器装备、工业自动化生产等领域对视频采集与处理系统小型化、集成化发展需求，基于Xilinx公司高性能Zynq-7000系列SoC芯片，搭建了一种小型化、集成化、通用化视频采集处理平台系统。通过充分发挥SoC芯片集成ARM处理器软件可编程和FPGA硬件可编程优势，提出了利用HLS工具将图像预处理算法快速打包生成IP核，在FPGA中实现图像算法硬件加速的设计方法，不仅保证了视频采集和处理的实时性，而且实现了视频处理设备小型化、集成化、低功耗设计。对系统软硬件设计和各组成部分原理进行了介绍，并以Sobel边缘检测算子为实例，对系统功能和性能与传统处理方法进行了对比测试，验证了系统的有效性。

Abstract:

As it is difficult for the traditional video processing systems to solve the contradiction problems among small size, low power, large data bandwidth and high processing speed, and in order to meet the small-integrated requirements of development in the fields of intelligent weapon equipments and industrial automation productions, a kind of small-integrated video acquisition and processing platform system based on SoC is constructed. Through taking advantages of the software programmable based Arm and the hard programmable based FPGA, a video preprocessing method using Vivado HLS video libraries is proposed to quickly package IP cores based on which the hardware accelerated algorithms are achieved in FPGA. The platform system not only meets the real-time requirements of video acquisition and processing but also achieves the designs of small-integrated and low power. The hardware and software of system are designed and the composition principles of system are introduced. The contrast analysis of system functions and performances are finished based the example of Sobel algorithm. The effectiveness of system is validated.
