《基于嵌入式μclinux的網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)》由會(huì)員上傳分享,免費(fèi)在線閱讀,更多相關(guān)內(nèi)容在教育資源-天天文庫(kù)。
1、大連理工大學(xué)碩士學(xué)位論文摘要傳統(tǒng)的模擬視頻監(jiān)控系統(tǒng)具有成本較高,需要鋪設(shè)專用線路,無(wú)法聯(lián)網(wǎng),需要耗費(fèi)大量的存儲(chǔ)介質(zhì)等缺點(diǎn)。隨著網(wǎng)絡(luò)的發(fā)展,新興的網(wǎng)絡(luò)視頻監(jiān)控克服了傳統(tǒng)模擬視頻監(jiān)控的局限性,充分利用了網(wǎng)絡(luò)資源,有助于提高性能,降低成本,是視頻監(jiān)控系統(tǒng)的發(fā)展方向。本文介紹了基于嵌入式gcLinux的網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)的設(shè)計(jì)和實(shí)現(xiàn)方法。該視頻監(jiān)控系統(tǒng)由攝像頭、云臺(tái)控制器、網(wǎng)絡(luò)視頻服務(wù)器以及客戶端Pc機(jī)等幾部分組成,文中首先論述了視頻監(jiān)控技術(shù)的兩大技術(shù)基礎(chǔ)~圖象處理技術(shù)和嵌入式操作系統(tǒng)相關(guān)技術(shù);然后介紹了視頻監(jiān)控系統(tǒng)服務(wù)器端硬件中幾個(gè)重要模塊的設(shè)計(jì),
2、包括圖像壓縮處理模塊、網(wǎng)絡(luò)接口模塊、實(shí)時(shí)時(shí)鐘模塊、云臺(tái)的控制、串口的應(yīng)用等;軟件部分詳細(xì)介紹了軟件的設(shè)計(jì)方案,包括嵌入式軟件開發(fā)環(huán)境的搭建,崛Linux內(nèi)核的編譯,以及視頻監(jiān)控軟件中多個(gè)任務(wù)的設(shè)計(jì)和軟件的調(diào)試與測(cè)試方法等;并介紹了網(wǎng)絡(luò)協(xié)議在本系統(tǒng)中的應(yīng)用。本文所介紹的網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)達(dá)到畫面播放流暢,清晰度高,幾乎無(wú)馬賽克效應(yīng)的效果,可在圖象監(jiān)控過(guò)程中,設(shè)置網(wǎng)絡(luò)攝象機(jī)參數(shù)和對(duì)云臺(tái)進(jìn)行控制。支持UDP/IP、TCP/IP、ARP、FTP、DHCP、舯、SMTP等多種協(xié)議,實(shí)現(xiàn)了網(wǎng)絡(luò)實(shí)時(shí)播放、允許多路切換和4路畫面同時(shí)播放、可以以FTP/MAI
