【摘要】：隨著嵌入式硬件和軟件的快速發(fā)展、互聯(lián)網(wǎng)的普及,傳統(tǒng)的安防和監(jiān)控領(lǐng)域開(kāi)始向高清數(shù)字化、智能化、聯(lián)網(wǎng)交互的方向發(fā)展,與此同時(shí)人們對(duì)社會(huì)公共安全領(lǐng)域的需求不斷遞增,使得整體視頻監(jiān)控行業(yè)的未來(lái)具有很大的發(fā)展空間。大量的安防廠商紛紛推出了自己的高清網(wǎng)絡(luò)相機(jī)設(shè)備,突出高清、智能、云端等創(chuàng)新點(diǎn)用以吸引用戶(hù)。 高清網(wǎng)絡(luò)相機(jī)作為相對(duì)獨(dú)立的互聯(lián)網(wǎng)產(chǎn)品,涉及到比較完整的嵌入式硬件和軟件設(shè)計(jì),包括位于前端的圖像傳感器和中間核心的數(shù)據(jù)處理單元兩大部分。主要的數(shù)據(jù)處理流程包括傳感器數(shù)據(jù)采集,原始圖像數(shù)據(jù)預(yù)處理,視頻編碼壓縮,存儲(chǔ)和網(wǎng)絡(luò)傳輸?shù)取?本課題主要是應(yīng)用TI的DM368平臺(tái)作為高清CCD網(wǎng)絡(luò)相機(jī)后端視頻壓縮子系統(tǒng),設(shè)計(jì)實(shí)現(xiàn)視頻編碼壓縮,存儲(chǔ)和網(wǎng)絡(luò)傳輸?shù)汝P(guān)鍵功能。高清CCD網(wǎng)絡(luò)相機(jī)使用了FPGA+SOC的整體設(shè)計(jì)方案,前端為FPGA驅(qū)動(dòng)的高清CCD圖像傳感器KAI-02150,后端為DM368視頻處理子系統(tǒng)。本文的工作重心是DM368平臺(tái)并且包含部分FPGA前端設(shè)計(jì),主要工作為DM368平臺(tái)的硬件和軟件設(shè)計(jì),以及一種基于FPGA的寬動(dòng)態(tài)增強(qiáng)算法的設(shè)計(jì)實(shí)現(xiàn)。DM368硬件系統(tǒng)設(shè)計(jì)包括ISIF圖像傳感器接口、高清分量視頻輸出接口、100/10M以太網(wǎng)接口、SD卡接口、UART接口、JTAG調(diào)試接口、DDR、 NandFlash以及電源模塊等。DM368軟件系統(tǒng)設(shè)計(jì)以SDK軟件架構(gòu)為基礎(chǔ),基于MontaVista Linux操作系統(tǒng),實(shí)現(xiàn)了由FPGA輸出的數(shù)字信號(hào)到DM368的驅(qū)動(dòng)模塊移植,視頻編碼模塊設(shè)計(jì),視頻保存模塊設(shè)計(jì),基于Live555的RTSP流媒體服務(wù)移植,以及客戶(hù)端軟件設(shè)計(jì)等。
[Abstract]:With the rapid development of the embedded hardware and software , the popularization of the Internet , the traditional security and monitoring fields begin to develop to the digital , intelligent and networked directions of the high definition . At the same time , the demand in the field of social public security is constantly increasing , so that the future of the whole video monitoring industry has great development space .

High - definition network camera as a relatively independent Internet product involves relatively complete embedded hardware and software design , including two parts of the front - end image sensor and the central core data processing unit . The main data processing flow includes sensor data acquisition , original image data preprocessing , video coding compression , storage and network transmission .

This thesis is mainly to use the DM368 platform of TI as the back - end video compression subsystem of high definition CCD network camera . The design realizes the key functions of video coding compression , storage and network transmission . The design of DM368 hardware system is based on the design of the FPGA + SOC . The design of DM368 hardware system includes the hardware and software design of the DM368 platform , the design of the video coding module , the design of the video storage module , the RTSP streaming media service migration based on Live555 , and the software design of the client .
