【摘要】：現(xiàn)代化的信息技術(shù)發(fā)展迅猛，與此同時(shí)數(shù)字多媒體技術(shù)也廣泛應(yīng)用于人們生活中為之提供更好的服務(wù)，隨之而來的是人們對視頻實(shí)時(shí)性以及圖像的質(zhì)量要求越來越高，傳統(tǒng)的數(shù)字視頻圖像處理技術(shù)已經(jīng)不能滿足人們的需求。國外的芯片長期占據(jù)圖像處理芯片的主要市場，但隨著國內(nèi)流片技術(shù)的提高，，具有自主知識產(chǎn)權(quán)的芯片相關(guān)技術(shù)也有待開發(fā)。因此，本文以Davinci技術(shù)的龍芯2F處理器為核心，利用BT.656視頻傳輸協(xié)議，提出了硬件與軟件相結(jié)合的視頻圖像處理的設(shè)計(jì)方案。 本文回顧了視頻圖像處理的發(fā)展歷程及現(xiàn)狀，對阿爾法視頻疊加技術(shù)，傳輸協(xié)議BT.656標(biāo)準(zhǔn)、VESA標(biāo)準(zhǔn)等相關(guān)技術(shù)做了簡單闡述，設(shè)計(jì)實(shí)現(xiàn)了基于龍芯2F的視頻處理系統(tǒng)，著重論述了系統(tǒng)的整體框架的設(shè)計(jì)以及其軟件子系統(tǒng)的設(shè)計(jì)實(shí)現(xiàn)過程。首先，在對整個(gè)系統(tǒng)的功能進(jìn)行分析的基礎(chǔ)上，介紹了系統(tǒng)的整個(gè)框架結(jié)構(gòu)，并通過介紹系統(tǒng)的硬件平臺，對系統(tǒng)的軟件子系統(tǒng)的需求進(jìn)行了分析；其次，對系統(tǒng)的軟件子系統(tǒng)的各個(gè)模塊的具體設(shè)計(jì)進(jìn)行了詳細(xì)描述；最后，提出了符合實(shí)際的測試方案，并給出測試結(jié)果分析。 通過系統(tǒng)的測試表明，軟硬件結(jié)合的視頻圖像處理技術(shù)能夠更好的保證圖像視頻的質(zhì)量以及對實(shí)時(shí)性傳輸?shù)囊蟆?br/>[Abstract]:With the rapid development of modern information technology, digital multimedia technology is also widely used in people's life to provide better services, followed by people to video real-time and image quality requirements more and more high. Traditional digital video image processing technology has not been able to meet the needs of people. Foreign chips have occupied the main market of image processing chips for a long time, but with the improvement of domestic streaming technology, Chip related technologies with independent intellectual property rights are also to be developed. Therefore, based on the Godson 2F processor of Davinci technology and BT.656 video transmission protocol, a design scheme of video image processing based on hardware and software is proposed in this paper. This paper reviews the development course and present situation of video image processing, describes the related technologies such as Alpha video superposition technology, BT.656 standard of transmission protocol and so on, and designs and implements a video processing system based on Longson 2F. The design of the whole frame of the system and the design and realization process of its software subsystem are discussed emphatically. Firstly, on the basis of analyzing the function of the whole system, the whole frame structure of the system is introduced. By introducing the hardware platform of the system, the requirements of the software subsystem of the system are analyzed. Secondly, the specific design of each module of the software subsystem of the system is described in detail. The test results are analyzed. The system tests show that the software and hardware combination of video image processing technology can better ensure the quality of image and video transmission requirements for real-time.
