【摘要】：互联网与嵌入式技术的快速发展促使视频监控技术进入了一个新的发展阶段,基于嵌入式Web技术的视频监控迅速成为未来监控行业发展的重要方向,而且视频监控系统的应用领域正在从大型公共场所逐步转向小型私人场所。由于现今快速的生活节奏使得人们照顾家庭的时间和精力都非常有限,而且伴随中国人口老龄化问题的突出,人们对家庭的关注不断提高,为此人们希望在外地出差或旅游的同时能够实时了解家人的生活状态,遇到突发事件能够及时采取措施。以当前的现实需求为出发点,结合嵌入式监控技术与Web技术,本课题提出了一种基于B/S监控模式的远程视频监控系统。该系统由S3C2416核心处理器和嵌入式Linux操作系统,以及其它外围设备组成,通过Web技术使监控系统接入到Internet,用户使用浏览器即可进行远程访问。系统首先利用V4L2采集技术从罗技C270摄像头采集视频图像,经过软压缩后输出JPEG格式的数据流,再通过系统无线模块RT5370以无线方式将视频数据传输至Internet。通过移植流媒体服务器(MJPG-streamer)和Web服务器(Thttpd)实现了视频图像的采集与传输和浏览器对服务器的远程控制,通过在HTML页面中嵌入applet小程序,实现了浏览器中视频图像的加载和显示。在互联网环境下,用户可以使用手机等移动设备的浏览器登录监控系统查看实时视频图像。此外,本课题还增加了智能识别功能,选用基于背景差分法的运动目标识别算法,并应用OpenCV函数库实现了运动物体的检测功能。当检测到有运动物体进入监控区域时,系统会自动触发邮件提醒功能,为用户发送提醒邮件。通过本课题设计的简单灵活的嵌入式Web远程视频监控系统既体现了对家庭的关爱,也在一定程度上兼顾了工作和家庭,具有一定的实用价值和现实意义。
[Abstract]:With the rapid development of Internet and embedded technology, video surveillance technology has entered a new stage of development. Video surveillance based on embedded Web technology has quickly become an important direction of the future monitoring industry. And the application of video surveillance system is gradually shifting from large public places to small private places. With the rapid pace of life, people have limited time and energy to take care of their families, and with the aging of China's population, people pay more and more attention to families. Therefore, people hope to know the living conditions of their families in real time while travelling or traveling, and to take timely measures in case of emergencies. Based on the current requirements and combining embedded monitoring technology with Web technology, this paper presents a remote video surveillance system based on B / S mode. The system is composed of S3C2416 core processor, embedded Linux operating system and other peripheral devices. Through Web technology, the monitoring system can be connected to Internet, and users can access it remotely by using browser. The system firstly collects video images from Logitech C270 camera by using V4L2 acquisition technology, outputs the data stream of JPEG format after soft compression, and then transmits video data to Internet by wireless module RT5370. By transplanting streaming media server MJPG-streamer and Web server Thttpdd), the collection and transmission of video image and remote control of server by browser are realized. By embedding applet Mini Programs in HTML page, the loading and displaying of video image in browser is realized. In the Internet environment, users can use mobile devices such as cell phone browser login monitoring system to view real-time video images. In addition, the intelligent recognition function is added, the moving object recognition algorithm based on background difference method is selected, and the detection function of moving object is realized by using OpenCV function library. When a moving object enters the monitoring area, the system automatically triggers the email alert function and sends a reminder message to the user. The simple and flexible embedded Web remote video surveillance system designed in this paper not only reflects the care for the family, but also gives consideration to the work and family to a certain extent, so it has certain practical value and practical significance.
