【摘要】：隨著圖像處理技術(shù)的不斷發(fā)展,越來越多的行業(yè)領(lǐng)域?qū)で蠛线m的監(jiān)控解決方案,且早已不再是公共安全領(lǐng)域、銀行領(lǐng)域的專有應(yīng)用,例如,考試的監(jiān)控、交通實時路況展現(xiàn)、檢測機關(guān)執(zhí)法、醫(yī)療保健等,持續(xù)升級的公共安全問題也使得安防監(jiān)控的地位不斷提高,由于直觀、簡潔、內(nèi)容豐富,實時性強、易于集中管理及控制等諸多優(yōu)點,視頻監(jiān)控被應(yīng)用在眾多場合。 本文是一種基于FPGA技術(shù)的視頻監(jiān)控系統(tǒng)設(shè)計方案。SOPC技術(shù)集合計算機技術(shù)、嵌入式開發(fā)技術(shù)、數(shù)字信號處理等專長,是電子設(shè)計領(lǐng)域的新的發(fā)展方向。通過在FPGA中利用SOPC技術(shù)嵌入Nios Ⅱ軟核及其他外設(shè),構(gòu)成完整的嵌入式可編程系統(tǒng)。與傳統(tǒng)的解決方案相比,該設(shè)計降低了系統(tǒng)成本、縮短了開發(fā)周期,能夠很好地應(yīng)對需求的變化進行快速升級。 本文的主要內(nèi)容如下： (1)研究了視頻監(jiān)控系統(tǒng)的發(fā)展進程及SOPC相關(guān)技術(shù)。 (2)設(shè)計實現(xiàn)了基于Nios Ⅱ嵌入式軟核的可編程硬件系統(tǒng)及基于FPGA的硬件邏輯設(shè)計。 (3)研究分析了COMS攝像頭的原理構(gòu)成和時序邏輯,設(shè)計實現(xiàn)了攝像頭芯片的配置、圖像數(shù)據(jù)采集以及存儲模塊的設(shè)計。 (4)研究了RTEMS實時嵌入式系統(tǒng)及編程接口,完成了RTEMS在Nios Ⅱ軟核上的運行。 (5)設(shè)計實現(xiàn)了基于TCP/IP協(xié)議的SOCKET編程,完成了DM9000A網(wǎng)絡(luò)芯片硬件設(shè)計和網(wǎng)絡(luò)驅(qū)動設(shè)計。 (6)最后詳細闡述了對各個模塊設(shè)計的驗證過程,測試結(jié)果表明該系統(tǒng)設(shè)計具有可行性和正確性。
[Abstract]:With the continuous development of image processing technology, more and more industries seek suitable monitoring solutions, and are no longer the public security field, banking domain exclusive applications, such as examination monitoring, traffic real-time road conditions show, The law enforcement, medical care, and continuous upgrading of the public safety problems of the inspection organs have also made the status of security and monitoring continuously enhanced. Because of its many advantages, such as intuitive, concise, rich in content, real-time, easy to centralized management and control, etc. Video surveillance is used in many situations. This paper is a design scheme of video surveillance system based on FPGA technology. SOPC technology gathers computer technology, embedded development technology, digital signal processing and so on. It is a new development direction in electronic design field. By embedding Nios 鈪，
