【摘要】：目前,由于頻段資源的緊缺,現(xiàn)無線傳播中干擾大,采用普通無線視頻系統(tǒng),傳輸時會出現(xiàn)較為嚴重的干擾,還需要占用較寬的頻段資源,視頻圖像質(zhì)量不高,并且整套系統(tǒng)價格也貴,不滿足現(xiàn)在使用的要求。本系統(tǒng)成功搭建了基于JZ7455平臺的無線視頻系統(tǒng),本課題分析了無線視頻系統(tǒng)的國內(nèi)外發(fā)展趨勢和應用領(lǐng)域,完成了從系統(tǒng)框架設(shè)計到不同的功能模塊的設(shè)計與實現(xiàn)。最終實現(xiàn)了射頻傳輸、攝像頭視頻采集、視頻圖像處理與存儲等相關(guān)功能。并且在各模塊的選擇等方面,具有比較高的可行性和優(yōu)勢性。按照項目功能需求搭建的軟件系統(tǒng),設(shè)計的各模塊經(jīng)得起多方面的功能比較,也可以根據(jù)實際場景再進行平臺的再次設(shè)計,將各自的功能發(fā)揮到了最好。本論文符合性價比、可靠性和兼容性等方面的考量,各子系統(tǒng)模塊以及整體具有較高的可移植性。本文首先對課題背景及相關(guān)的圖像處理基本以及無線技術(shù)做了基本介紹;其次,通過分析需求,進行系統(tǒng)的總體設(shè)計,完成了硬件和軟件設(shè)計,并對各個功能模塊的設(shè)計與實現(xiàn)進行了詳細闡述,以及對系統(tǒng)做了相關(guān)的測試工作。
[Abstract]:At present, due to the shortage of frequency band resources, there is a large interference in the current wireless transmission, the use of ordinary wireless video system, transmission will appear more serious interference, but also need to occupy a wide band of resources, video image quality is not high. And the whole system is expensive, not to meet the requirements of the current use. This system successfully built a wireless video system based on JZ7455 platform. This paper analyzes the development trend and application field of wireless video system at home and abroad, and completes the design and implementation of different functional modules from the system framework design. Finally, radio frequency transmission and video capture of camera are realized. Video image processing and storage and other related functions. And in the selection of modules and other aspects, has a high feasibility and superiority. According to the project functional requirements to build a software system. Each module of the design can withstand a variety of functional comparisons, but also can be re-designed according to the actual scenes, their functions to play the best. This paper is in line with the cost-effective. Considering the reliability and compatibility, each subsystem module and the whole system have high portability. Firstly, this paper introduces the background of the subject, the basic image processing and wireless technology. Secondly, through the analysis of the requirements, the overall design of the system, the completion of the hardware and software design, and the design and implementation of each functional module are described in detail, as well as the system to do the relevant testing work.
