文档介绍：中文摘要中文摘要随着视频监控系统的迅速发展,市场应用不断向深度、广度拓展,促进了视频监控技术的快速进步。为了满足能够同时看更广泛的监控场景的市场需求,广角和全景视频监控得以实现技术上的飞跃。根据实际需求,本文根据视频拼接技术的基本原理,设计了一个基于SOPC (System On aPro铲ammable Chip)技术的宽视角视频监控系统。目的是为了实现将多路摄像头输出的视频信号进行实时无缝拼接,从而获得一个可以通过VGA 等接口在输出设备上显示的宽视角的视频流。系统在视频采集电路的控制下,视频解码芯片将来自多个摄像头的多路视频信号转化为数字信号,通过图像预处理模块进行修正,数据送入SOPC系统实现每帧图像的无缝拼接后,由视频显示控制电路控制视频数模转换芯片将拼接后的视频数据实时输出至显示器。分别测试了系统中各个模块的功能,并检验了系统的整体运行效果。实验表明,系统的各个模块在功能上能够满足实际需要,系统运行稳定可靠。运用到实际安防领域中,可以提升管理人员的工作效率、减少视觉负担、缓解工作压力。而且结构简单集成度高、可靠性好、画面清晰流畅、功耗和开发成本低、体积小、易于产品维护,具有一定的实际应用价值。关键词:全景视频;SOPC;视频拼接 Abstract Abstract With thedevelopment ofvideo monitoring system,the application ofmarket which isrelated tovideo monitoring continuously expands depth and booming application ofmarket promotes theprogress ofvideo monitoring technology, atthesame time,wide angle and Panoramic Video Surveillance realizetechnical leap tomeet market demand thatmonitors much more widely.
