【摘要】：本文首先對(duì)目前市場(chǎng)上的視頻監(jiān)控系統(tǒng)進(jìn)行了解研究，發(fā)現(xiàn)現(xiàn)有的監(jiān)控系統(tǒng)具一些缺點(diǎn)，搭建非常繁瑣，并且受到了距離的限制。所以本文就在此提出了一種基于ARM的遠(yuǎn)程視頻監(jiān)控系統(tǒng)。 本視頻監(jiān)控系統(tǒng)采用ARM920T為內(nèi)核的微處理器來(lái)處理圖像數(shù)據(jù)采集圖像數(shù)據(jù)使用到了USB攝像頭（ZC301芯片），并且使用了無(wú)線(xiàn)網(wǎng)絡(luò)進(jìn)行圖像數(shù)據(jù)的傳輸，實(shí)現(xiàn)了嵌入式的視頻服務(wù)器和web服務(wù)器（Boa），，還添加了視頻跟蹤的功能，使用的是幀間差分法。當(dāng)那個(gè)Boa接收到HTTP請(qǐng)求后，系統(tǒng)開(kāi)始調(diào)用CGI程序，這時(shí)CGI程序開(kāi)始與視頻服務(wù)器進(jìn)行交流，這個(gè)時(shí)候視頻服務(wù)器開(kāi)始驅(qū)動(dòng)攝像頭來(lái)采集與處理圖像數(shù)據(jù)，并且將數(shù)據(jù)發(fā)送給Boa，Boa將數(shù)據(jù)用網(wǎng)頁(yè)傳給客戶(hù)端，通過(guò)Applet技術(shù)嵌入到HTML網(wǎng)頁(yè)中來(lái)顯示視頻圖像數(shù)據(jù)，這個(gè)時(shí)候用戶(hù)就可以實(shí)現(xiàn)了在瀏覽器上監(jiān)控我們所需要監(jiān)控的畫(huà)面（通過(guò)PC機(jī)端和智能手機(jī)端）、設(shè)置監(jiān)控系統(tǒng)的配置參數(shù)等操作，并且可以實(shí)現(xiàn)簡(jiǎn)單的運(yùn)動(dòng)檢測(cè)與跟蹤。 本文是首先介紹了遠(yuǎn)程視頻監(jiān)控系統(tǒng)的軟、硬件平臺(tái)的結(jié)構(gòu)，緊接著闡述了搭建軟件平臺(tái)的過(guò)程，還有一些移植工作（Bootloader、Linux內(nèi)核以及yaffs文件系統(tǒng)），USB攝像頭和無(wú)線(xiàn)網(wǎng)卡的設(shè)備驅(qū)動(dòng)程序的設(shè)計(jì)；然后討論了Web服務(wù)器和MJPG-Streamer視頻服務(wù)器的編譯，詳細(xì)的分析了CGI程序以及HTML網(wǎng)頁(yè)的設(shè)計(jì)與實(shí)現(xiàn)，通過(guò)Applet技術(shù)嵌入到HTML中來(lái)顯示視頻圖像數(shù)據(jù)；最后介紹了幀間差分法運(yùn)動(dòng)跟蹤的原理。經(jīng)實(shí)驗(yàn)測(cè)試，該系統(tǒng)實(shí)現(xiàn)了在瀏覽器上監(jiān)控我們所需要監(jiān)控的畫(huà)面（通過(guò)PC機(jī)端和智能手機(jī)端），達(dá)到了預(yù)期效果。
[Abstract]:Firstly, this paper studies the current video surveillance system in the market, and finds that the existing monitoring system has some shortcomings, the building is very cumbersome, and is limited by the distance. So this paper puts forward a remote video surveillance system based on ARM. This video monitoring system uses ARM920T microprocessor to process image data, and uses USB camera (ZC301 chip), and uses wireless network to transmit image data. The embedded video server and web server (Boa), also add the function of video tracking, using the method of inter-frame difference. When the Boa received the HTTP request, the system began to call the CGI program, and then the CGI program began to communicate with the video server, and the video server began to drive the camera to collect and process image data. And send the data to the Boa,Boa to pass the data to the client, and embed it into the HTML web page through the Applet technology to display the video image data. At this time, the user can monitor the screen we need on the browser (via PC and smart phone), set the configuration parameters of the monitoring system, and can achieve simple motion detection and tracking. This paper first introduces the structure of the software and hardware platform of the remote video surveillance system, and then describes the process of building the software platform. There are also some transplanting work (Bootloader,Linux kernel and yaffs file system) to design the device driver of Bootloader,Linux camera and wireless network card. Then, the compilation of Web server and MJPG-Streamer video server is discussed. The CGI program and the design and implementation of HTML web page are analyzed in detail, and the video image data are displayed by Applet technology embedded into HTML. Finally, the principle of motion tracking by inter-frame differential method is introduced. The experimental results show that the system can monitor the images we need on the browser (via PC and smart phone), and achieve the desired results.
