【摘要】：随着图像处理技术的不断发展,越来越多的行业领域寻求合适的监控解决方案,且早已不再是公共安全领域、银行领域的专有应用,例如,考试的监控、交通实时路况展现、检测机关执法、医疗保健等,持续升级的公共安全问题也使得安防监控的地位不断提高,由于直观、简洁、内容丰富,实时性强、易于集中管理及控制等诸多优点,视频监控被应用在众多场合。 本文是一种基于FPGA技术的视频监控系统设计方案。SOPC技术集合计算机技术、嵌入式开发技术、数字信号处理等专长,是电子设计领域的新的发展方向。通过在FPGA中利用SOPC技术嵌入Nios Ⅱ软核及其他外设,构成完整的嵌入式可编程系统。与传统的解决方案相比,该设计降低了系统成本、缩短了开发周期,能够很好地应对需求的变化进行快速升级。 本文的主要内容如下： (1)研究了视频监控系统的发展进程及SOPC相关技术。 (2)设计实现了基于Nios Ⅱ嵌入式软核的可编程硬件系统及基于FPGA的硬件逻辑设计。 (3)研究分析了COMS摄像头的原理构成和时序逻辑,设计实现了摄像头芯片的配置、图像数据采集以及存储模块的设计。 (4)研究了RTEMS实时嵌入式系统及编程接口,完成了RTEMS在Nios Ⅱ软核上的运行。 (5)设计实现了基于TCP/IP协议的SOCKET编程,完成了DM9000A网络芯片硬件设计和网络驱动设计。 (6)最后详细阐述了对各个模块设计的验证过程,测试结果表明该系统设计具有可行性和正确性。
[Abstract]:With the continuous development of image processing technology, more and more industries seek suitable monitoring solutions, and are no longer the public security field, banking domain exclusive applications, such as examination monitoring, traffic real-time road conditions show, The law enforcement, medical care, and continuous upgrading of the public safety problems of the inspection organs have also made the status of security and monitoring continuously enhanced. Because of its many advantages, such as intuitive, concise, rich in content, real-time, easy to centralized management and control, etc. Video surveillance is used in many situations. This paper is a design scheme of video surveillance system based on FPGA technology. SOPC technology gathers computer technology, embedded development technology, digital signal processing and so on. It is a new development direction in electronic design field. By embedding Nios 鈪，
