1、南京航空航天大學(xué)碩士學(xué)位論文摘要快速發(fā)展的嵌入式系統(tǒng)技術(shù),與網(wǎng)絡(luò)技術(shù)相結(jié)合,產(chǎn)生了眾多的應(yīng)用。包括基于嵌入式系統(tǒng)的網(wǎng)絡(luò)視頻監(jiān)控技術(shù)。實現(xiàn)基于網(wǎng)絡(luò)的視頻監(jiān)控系統(tǒng)的關(guān)鍵是一種嵌入式設(shè)備,它應(yīng)該能夠采集視頻數(shù)據(jù)并通過網(wǎng)絡(luò)進行傳輸。在本課題中,將實現(xiàn)這樣的系統(tǒng),命名為CBTVIEW(以實驗室名字命名)。本文把嵌入式系統(tǒng)開發(fā)技術(shù)與Internet技術(shù)相結(jié)合,實現(xiàn)了基于嵌入式Linux的遠(yuǎn)程圖像監(jiān)控系統(tǒng)。該監(jiān)控系統(tǒng)作為服務(wù)器端的是嵌入式Linux系統(tǒng)平臺,它采用ARM內(nèi)核的S3C2410芯片作為處理器,服務(wù)器程序
2、在其上以后臺方式運行,等待監(jiān)控系統(tǒng)環(huán)境中客戶機使用瀏覽器發(fā)送的訪問請求。首先簡要介紹了系統(tǒng)的實現(xiàn)方案,接著說明了嵌入式系統(tǒng)開發(fā)的特點。討論了嵌入式開發(fā)環(huán)境的建立和嵌入式Linux下USB接口攝像頭驅(qū)動的加載,接著重點論述了如何利用Video4LinuxAPI函數(shù)實現(xiàn)視頻數(shù)據(jù)采集,以及網(wǎng)絡(luò)通信的具體實現(xiàn)過程和方法。最后著重實現(xiàn)了嵌入式Web服務(wù)器的構(gòu)建,并實現(xiàn)了針對基于B/S模式的網(wǎng)絡(luò)監(jiān)控系統(tǒng)結(jié)構(gòu)。另外還在系統(tǒng)中集成了對云臺的控制,擴大了監(jiān)控范圍。最后在局域網(wǎng)的實驗環(huán)境下,實現(xiàn)了對遠(yuǎn)程環(huán)境的網(wǎng)絡(luò)監(jiān)控功能
