【摘要】：互聯(lián)網(wǎng)與嵌入式技術(shù)的快速發(fā)展促使視頻監(jiān)控技術(shù)進(jìn)入了一個(gè)新的發(fā)展階段,基于嵌入式Web技術(shù)的視頻監(jiān)控迅速成為未來(lái)監(jiān)控行業(yè)發(fā)展的重要方向,而且視頻監(jiān)控系統(tǒng)的應(yīng)用領(lǐng)域正在從大型公共場(chǎng)所逐步轉(zhuǎn)向小型私人場(chǎng)所。由于現(xiàn)今快速的生活節(jié)奏使得人們照顧家庭的時(shí)間和精力都非常有限,而且伴隨中國(guó)人口老齡化問(wèn)題的突出,人們對(duì)家庭的關(guān)注不斷提高,為此人們希望在外地出差或旅游的同時(shí)能夠?qū)崟r(shí)了解家人的生活狀態(tài),遇到突發(fā)事件能夠及時(shí)采取措施。以當(dāng)前的現(xiàn)實(shí)需求為出發(fā)點(diǎn),結(jié)合嵌入式監(jiān)控技術(shù)與Web技術(shù),本課題提出了一種基于B/S監(jiān)控模式的遠(yuǎn)程視頻監(jiān)控系統(tǒng)。該系統(tǒng)由S3C2416核心處理器和嵌入式Linux操作系統(tǒng),以及其它外圍設(shè)備組成,通過(guò)Web技術(shù)使監(jiān)控系統(tǒng)接入到Internet,用戶(hù)使用瀏覽器即可進(jìn)行遠(yuǎn)程訪(fǎng)問(wèn)。系統(tǒng)首先利用V4L2采集技術(shù)從羅技C270攝像頭采集視頻圖像,經(jīng)過(guò)軟壓縮后輸出JPEG格式的數(shù)據(jù)流,再通過(guò)系統(tǒng)無(wú)線(xiàn)模塊RT5370以無(wú)線(xiàn)方式將視頻數(shù)據(jù)傳輸至Internet。通過(guò)移植流媒體服務(wù)器(MJPG-streamer)和Web服務(wù)器(Thttpd)實(shí)現(xiàn)了視頻圖像的采集與傳輸和瀏覽器對(duì)服務(wù)器的遠(yuǎn)程控制,通過(guò)在HTML頁(yè)面中嵌入applet小程序,實(shí)現(xiàn)了瀏覽器中視頻圖像的加載和顯示。在互聯(lián)網(wǎng)環(huán)境下,用戶(hù)可以使用手機(jī)等移動(dòng)設(shè)備的瀏覽器登錄監(jiān)控系統(tǒng)查看實(shí)時(shí)視頻圖像。此外,本課題還增加了智能識(shí)別功能,選用基于背景差分法的運(yùn)動(dòng)目標(biāo)識(shí)別算法,并應(yīng)用OpenCV函數(shù)庫(kù)實(shí)現(xiàn)了運(yùn)動(dòng)物體的檢測(cè)功能。當(dāng)檢測(cè)到有運(yùn)動(dòng)物體進(jìn)入監(jiān)控區(qū)域時(shí),系統(tǒng)會(huì)自動(dòng)觸發(fā)郵件提醒功能,為用戶(hù)發(fā)送提醒郵件。通過(guò)本課題設(shè)計(jì)的簡(jiǎn)單靈活的嵌入式Web遠(yuǎn)程視頻監(jiān)控系統(tǒng)既體現(xiàn)了對(duì)家庭的關(guān)愛(ài),也在一定程度上兼顧了工作和家庭,具有一定的實(shí)用價(jià)值和現(xiàn)實(shí)意義。
[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.
