【摘要】：隨著3G網(wǎng)絡(luò)技術(shù)的逐漸成熟和4G網(wǎng)絡(luò)的快速發(fā)展,以及圖像數(shù)據(jù)處理技術(shù)和嵌入式技術(shù)的迅速發(fā)展,視頻監(jiān)控系統(tǒng)進(jìn)入了一個(gè)更加廣闊的第三代數(shù)字化網(wǎng)絡(luò)化視頻監(jiān)控時(shí)代。如今,社會(huì)上的治安狀況日趨復(fù)雜,不斷出現(xiàn)的公共安全新問題和城市犯罪高發(fā)生率等現(xiàn)象都迫切需要加快發(fā)展無線視頻監(jiān)控技術(shù),因此,基于無線網(wǎng)絡(luò)的嵌入式遠(yuǎn)程視頻監(jiān)控系統(tǒng)已成為視頻監(jiān)控開發(fā)領(lǐng)域的主要趨勢。 本文研究設(shè)計(jì)了基于3G網(wǎng)絡(luò)的智能手機(jī)視頻監(jiān)控系統(tǒng)。該系統(tǒng)根據(jù)功能劃分為采集模塊、編碼模塊、傳輸模塊、顯示模塊,采用的技術(shù)主要有H.264視頻壓縮編碼技術(shù)、3G移動(dòng)通信技術(shù)、FFmpeg技術(shù),Android應(yīng)用軟件開發(fā)技術(shù)。本文的視頻監(jiān)控系統(tǒng)需要完成在服務(wù)端和客戶端的視頻播放工作,具體的工作流程：首先搭載了一個(gè)開發(fā)平臺(tái),以ARMll的S3C6410處理器的開發(fā)板和電腦上的虛擬機(jī)Linux系統(tǒng)共同組成,在此基礎(chǔ)上,完成軟硬件開發(fā)環(huán)境的構(gòu)建,即對嵌入式系統(tǒng)進(jìn)行交叉編譯環(huán)境建立和目標(biāo)板Linux操作系統(tǒng)裁剪移植,通過這個(gè)平臺(tái)完成視頻的采集和編碼,并且完成服務(wù)端的視頻解碼顯示；接著通過3G模塊中興AD3812完成基于TCP/IP協(xié)議的無線視頻傳輸工作,最后,搭建Android應(yīng)用開發(fā)平臺(tái),在此平臺(tái)上開發(fā)出一款視頻流播放器,完成視頻的播放顯示功能。 測試表明本文設(shè)計(jì)的基于3G無線嵌入式視頻監(jiān)控系統(tǒng)實(shí)現(xiàn)了視頻監(jiān)控的基本功能,在功耗、體積、實(shí)時(shí)性、可移動(dòng)性和可擴(kuò)展性等方面有明顯優(yōu)勢,具有良好的應(yīng)用空間。
[Abstract]:With the gradual maturity of 3G network technology and the rapid development of 4G network, as well as the rapid development of image data processing technology and embedded technology, The video surveillance system has entered a broader era of digital and networked video surveillance. Nowadays, the security situation in society is becoming more and more complicated. The emerging problems of public safety and the high incidence of urban crime are all urgent to speed up the development of wireless video surveillance technology. Embedded remote video surveillance system based on wireless network has become the main trend in the field of video surveillance and development. This paper studies and designs a video surveillance system of smart phone based on 3G network. The system is divided into three modules according to its functions: acquisition module, coding module, transmission module and display module. The main technologies adopted include H.264 video compression and coding technology and 3G mobile communication technology FFmpeg technology and Android application software development technology. The specific workflow: first, a development platform is built, which is composed of the development board of ARMll S3C6410 processor and the virtual machine Linux system on the computer. On this basis, the software and hardware development environment is constructed. That is, the embedded system is cross-compiled environment and target board Linux operating system cut and transplanted, through this platform to complete the collection and coding of video, and the server end of the video decoding display; Then the wireless video transmission based on TCP/IP protocol is completed by ZTE AD3812, the 3G module. Finally, the Android application development platform is built, and a video streaming player is developed on this platform to complete the video playback and display function. The test results show that the wireless embedded video surveillance system based on 3G has realized the basic functions of video surveillance, and has obvious advantages in power consumption, volume, real-time, mobility and scalability, and has good application space.
