【摘要】：隨著嵌入式技術(shù)、視頻處理技術(shù)和網(wǎng)絡(luò)技術(shù)的日益壯大,視頻監(jiān)控正往系統(tǒng)嵌入式的無線視頻監(jiān)控的方向發(fā)展。與傳統(tǒng)視頻監(jiān)控系統(tǒng)相比,該系統(tǒng)具有體積小、運行穩(wěn)定、可裁剪等優(yōu)點,是將來視頻監(jiān)控領(lǐng)域一個很重要的發(fā)展方向。因此本文基于室內(nèi)安全與無線WiFi視頻傳輸技術(shù),對嵌入式OpenWrt的無線視頻監(jiān)控系統(tǒng)進(jìn)行了設(shè)計與實現(xiàn)。論文的主要工作如下:1、本文首先從視頻監(jiān)控系統(tǒng)的研究背景及意義出發(fā),分析了國內(nèi)外發(fā)展現(xiàn)狀和應(yīng)用前景,并對當(dāng)前市場進(jìn)行了調(diào)研;然后通過分析項目對功能和性能的需求,以及相關(guān)技術(shù)的可行性,提出了一種新的嵌入式OpenWrt無線視頻監(jiān)控的總體設(shè)計方案。2、本文采用以MIPS 24Kc為核心處理器的RT5350開發(fā)板為硬件平臺,嵌入式OpenWrt路由器操作系統(tǒng)為軟件開發(fā)平臺,并且結(jié)合免驅(qū)USB攝像頭、基于V4L2接口的Streamer-MJPEG視頻服務(wù)器軟件和WiFi技術(shù),設(shè)計和實現(xiàn)了基于嵌入式OpenWrt的無線視頻監(jiān)控系統(tǒng);在硬件方面采用模塊化設(shè)計,其中包括:無線通信模塊(硬件開發(fā)平臺)、視頻監(jiān)控模塊(USB攝像頭)、客戶端模塊(手機/電腦)。在系統(tǒng)軟件方面,搭建了OpenWrt系統(tǒng),添加了LuCI Web界面,針對視頻的采集編寫了UVC和V4L2接口的驅(qū)動程序;在硬件平臺中添加了用于視頻采集和傳輸?shù)幕赩4L2接口的Streamer-MJPEG視頻服務(wù)器軟件,將V4L2接口中從攝像頭獲取的數(shù)據(jù)幀,以Web方式通過硬件平臺組建的WiFi傳輸?shù)娇蛻舳?用戶只需要手機/電腦就能實現(xiàn)視頻監(jiān)控。3、測試結(jié)果顯示,整個系統(tǒng)運行穩(wěn)定,手機和電腦都能連接到系統(tǒng)WiFi信號,通過手機上的視頻監(jiān)管軟件和電腦上的瀏覽器都可以清晰流暢的觀看監(jiān)控視頻。本文所設(shè)計的嵌入式無線視頻監(jiān)控系統(tǒng)實現(xiàn)了項目預(yù)期目標(biāo)。
[Abstract]:With the development of embedded technology, video processing technology and network technology, video surveillance is developing towards embedded wireless video surveillance system. Compared with traditional video surveillance system, the system is small in size and stable in operation. The advantages of tailoring are a very important development direction in the field of video surveillance in the future. Therefore, this paper based on indoor security and wireless WiFi video transmission technology, This paper designs and implements the wireless video surveillance system of embedded OpenWrt. The main work of this paper is as follows: 1. Firstly, from the research background and significance of the video surveillance system, this paper analyzes the development status and application prospect of the video surveillance system at home and abroad. And the current market research, and then through the analysis of the project requirements for function and performance, and the feasibility of related technologies, In this paper, a new design scheme of embedded OpenWrt wireless video surveillance is proposed. In this paper, the RT5350 development board with MIPS 24Kc as the core processor is used as the hardware platform, and the embedded OpenWrt router operating system is used as the software development platform. The wireless video surveillance system based on embedded OpenWrt is designed and implemented based on the Streamer-MJPEG video server software and WiFi technology based on V4L2 interface. It includes: wireless communication module (hardware development platform, video monitor module, USB camera, client module (mobile phone / computer, etc.). In system software, OpenWrt system is built, and LuCI Web interface is added. The driver of UVC and V4L2 interface is written for video acquisition, and the Streamer-MJPEG video server software based on V4L2 interface is added to the hardware platform. The WiFi constructed by the hardware platform of Web is transmitted to the client. The user only needs the mobile phone / computer to realize the video surveillance. The test results show that the whole system is running stably, and the mobile phone and computer can be connected to the system WiFi signal. The video monitoring software on the mobile phone and the browser on the computer can watch the video clearly and fluently. The embedded wireless video monitoring system designed in this paper achieves the expected goal of the project.
