【摘要】 随着我国经济的高速发展,电力网络规模、交通运输、银行业务、金融业务等得到了快速的发展,而这些业务面临提高效率,增强安全等一系列问题。视频监控系统担负视频监控、录像、报警等功能,交通运输、银行业务等业务的高速发展对视频监控提出了更高的要求,如视频监控的数字化、智能化、网络化。在视频监控系统中,视频的采集,字符信息叠加,运动图像的检测,监控视频的显示等是视频监控系统不可避免的技术问题。本文针对TW2834视频控制器,对视频监控系统的相关技术进行了探讨。本文介绍了TW2834视频控制器的特点,并对字符叠加、运动检测、多画面显示的不同实现方法进行了分析比较。完成了利用TW2834视频控制器实现字符叠加,运动检测和多画面显示的硬件设计和软件设计。最后对TW2834在视频监控系统中所用到的字符叠加技术,运动图像检测技术,多画面显示技术进行了总结。论文的研究工作可以为以后视频监控系统的进一步完善提供重要的思考。更多还原

【Abstract】 As china’s rapid economic development, electricity network size, traffic transportation, banking operation, finance services, etc. have been rapid development. These businesses in face of the matter of improve efficency, enhance security and other series of problems. Video surveillance system responsible for video surveillance, video record, alarm and other functions. Traffic transportation, finance services and other services demand the higher quality of video surveillance system, such as digital video surveillance, intelligence, networking. In video surveillance system, overlay characters, motion detect, video display is inevitable technical problems.This article discusses the related technology of video surveillance system based on TW2834 video controller, discusses the charateristics of TW2834 controller and analysises the different implement methods of characters overlay, motion detection and multi-picture display. Complete the hardware design and software design of characters overlay, motion detetion and multi-picture display based on TW2834. On the foundation of these works, summarizes the key technologies of TW2834 controller used in video surveillance system. The research work of this article can be used for reference to future development of video surveillance system.更多还原
