【摘要】:智能監(jiān)控系統(tǒng)有著使用方便、反應(yīng)快捷、界面直觀的特點(diǎn)。家庭監(jiān)控系統(tǒng)是智能家居安防系統(tǒng)中的關(guān)鍵組成部分。隨著人們生活水平的提高,對(duì)生活質(zhì)量的要求也日益顯著;無線網(wǎng)絡(luò)迅速發(fā)展,“無線城市”的進(jìn)一步推廣,使得無線網(wǎng)絡(luò)接入無處不在,方便了進(jìn)行網(wǎng)絡(luò)應(yīng)用。特別是當(dāng)今計(jì)算機(jī)通信技術(shù)、網(wǎng)絡(luò)傳輸技術(shù)、視頻圖像識(shí)別處理技術(shù)的快速發(fā)展和相關(guān)硬件條件的日益完善,發(fā)展了傳統(tǒng)的視頻監(jiān)控方式,化有線傳輸為無線傳輸,化被動(dòng)監(jiān)控為主動(dòng)監(jiān)控。3G和無線WiFi網(wǎng)絡(luò)的出現(xiàn),給智能監(jiān)控系統(tǒng)提供了完美的解決方案。不但節(jié)約資源成本,而且增加終端的可移動(dòng)性和便攜性。 本文主要研究基于無線網(wǎng)絡(luò)的家庭主動(dòng)監(jiān)控系統(tǒng)。主動(dòng)視頻監(jiān)控與被動(dòng)視頻監(jiān)控相比,可減少人的干預(yù),主動(dòng)執(zhí)行監(jiān)控程序設(shè)定的任務(wù),主要體現(xiàn)在圖像分析與理解、視頻的編解碼兩方面。文章研究了主動(dòng)視頻監(jiān)控中的關(guān)鍵技術(shù),包括Linux環(huán)境的搭建、運(yùn)動(dòng)物體檢測(cè)技術(shù)、報(bào)警機(jī)制、視頻編解碼、圖像的實(shí)時(shí)傳輸,并進(jìn)行比較選擇。對(duì)系統(tǒng)進(jìn)行了總體方案設(shè)計(jì)和需求分析,該系統(tǒng)的主要功能表現(xiàn)在能實(shí)時(shí)判定監(jiān)控區(qū)域中是否存在運(yùn)動(dòng)目標(biāo),并將現(xiàn)場(chǎng)圖像傳遞給監(jiān)控主機(jī)進(jìn)行顯示。WiFi網(wǎng)絡(luò)的大帶寬解決了傳輸速率對(duì)實(shí)時(shí)視頻圖像的影響,選用具有雙ARM架構(gòu)的海信hi3520視頻處理器,并搭建交叉編譯環(huán)境,結(jié)合H.264視頻壓縮編碼,提高了系統(tǒng)監(jiān)控質(zhì)量。該系統(tǒng)能對(duì)監(jiān)控目標(biāo)區(qū)域的異常運(yùn)動(dòng)物體進(jìn)行檢測(cè)并及時(shí)報(bào)警,高的傳輸速率能夠保證實(shí)時(shí)傳輸高清晰監(jiān)控圖像。 本文的整個(gè)系統(tǒng)架構(gòu)采用的是B/S模式,即瀏覽器端/服務(wù)器端模式。瀏覽器端采用的是安裝有Linux操作系統(tǒng)的PC機(jī),服務(wù)器端采用的是搭載Linux系統(tǒng),燒寫含有運(yùn)動(dòng)目標(biāo)檢測(cè)算法的ARM11內(nèi)核的開發(fā)板。通過對(duì)瀏覽器端和服務(wù)器端的軟件設(shè)計(jì),進(jìn)行了相關(guān)驅(qū)動(dòng)的開發(fā)。試驗(yàn)測(cè)試表明,該系統(tǒng)不僅具有傳統(tǒng)視頻監(jiān)控的采集、遠(yuǎn)程監(jiān)控功能,而且可實(shí)現(xiàn)主動(dòng)抓拍監(jiān)控區(qū)域中運(yùn)動(dòng)目標(biāo)圖像幀,通過Internet還可實(shí)現(xiàn)圖像的上傳。實(shí)現(xiàn)了實(shí)時(shí)的視頻監(jiān)控畫面,優(yōu)點(diǎn)顯著,市場(chǎng)應(yīng)用價(jià)值高。
[Abstract]:Intelligent monitoring system has the characteristics of convenient use, quick response and intuitive interface. The home monitoring system is a key component of the intelligent home security system. With the improvement of people's living standard. The demand for quality of life is also increasingly evident; With the rapid development of wireless network and the further promotion of "wireless city", wireless network access is ubiquitous and convenient for network application, especially computer communication technology and network transmission technology. With the rapid development of video image recognition and processing technology and the improvement of related hardware conditions, the traditional video surveillance mode has been developed to transform wired transmission into wireless transmission. Passive monitoring is the emergence of active monitoring. 3G and wireless WiFi network. It provides a perfect solution for intelligent monitoring system. It not only saves the cost of resources, but also increases the mobility and portability of the terminal. This paper mainly studies the home active monitoring system based on wireless network. Compared with passive video surveillance, active video monitoring can reduce human intervention and implement the task of monitoring program. This paper studies the key technologies of active video surveillance, including the construction of Linux environment, the detection technology of moving objects, and the alarm mechanism. Video coding and decoding, real-time image transmission, and comparison and selection. The overall scheme design and requirement analysis are carried out. The main function of the system is to determine whether there are moving targets in the monitoring area in real time. And the large bandwidth of the field image is transferred to the monitor host to display. WiFi network, which solves the influence of the transmission rate on the real time video image. Select Hisense hi3520 video processor with dual ARM architecture, and build a cross-compiling environment, combined with H.264 video compression coding. The system can detect and alarm the abnormal moving objects in the target area in time, and the high transmission rate can guarantee the real-time transmission of high-definition monitoring images. The whole system architecture of this paper is based on B / S mode, that is, browser / server mode. The browser uses PC with Linux operating system. The server uses the Linux system to burn down the development board of the ARM11 kernel which contains the moving target detection algorithm. Through the software design of browser and server. The test results show that the system not only has the functions of traditional video monitoring and remote monitoring, but also can capture the image frame of moving object in the monitoring area. Image upload can also be realized through Internet, and real-time video surveillance screen is realized, which has obvious advantages and high market application value.
