基于FPGA的嵌入式视频采集系统设计

Design of Embedded Video Acquisition System Based on FPGA

随着数字技术的飞速发展,视频采集与处理技术在众多领域有着越来越广泛的应用。当前市场上已出现多种视频采集卡,但由于视频数据量大,很多都无法满足工业现场的需求,本文主要研究数字视频图像的获取,以及嵌入式图像处理技术在FPGA芯片上的实现并利用FPGA产生数字视频流控制信号在LCD上还原采集的模拟视频图像,具体阐述了系统硬件平台设计以及软件编写流程,最后对系统主要功能模块仿真,并对系统进行软硬件综合调试。

With the rapid development of digital technology, video capture and processing technology has become increasingly widespread in many fields of application. Currently there has emerged on the market d variety of video capture card. However, due to large amount of video data, many are unable to meet the needs of the industrial site. This paper mainly studies the digital video image acquisition and the implementation of embedded image processing technology on FPGA chip and using digital video stream control signals produced by FPGA to restore the sampled analog video image on the LCD, then it describes the hardware platform design and software development processes, and finally, simulates the main function modules of the system and debug software and hardware systems synthetically.
