【摘要】：目前,由于频段资源的紧缺,现无线传播中干扰大,采用普通无线视频系统,传输时会出现较为严重的干扰,还需要占用较宽的频段资源,视频图像质量不高,并且整套系统价格也贵,不满足现在使用的要求。本系统成功搭建了基于JZ7455平台的无线视频系统,本课题分析了无线视频系统的国内外发展趋势和应用领域,完成了从系统框架设计到不同的功能模块的设计与实现。最终实现了射频传输、摄像头视频采集、视频图像处理与存储等相关功能。并且在各模块的选择等方面,具有比较高的可行性和优势性。按照项目功能需求搭建的软件系统,设计的各模块经得起多方面的功能比较,也可以根据实际场景再进行平台的再次设计,将各自的功能发挥到了最好。本论文符合性价比、可靠性和兼容性等方面的考量,各子系统模块以及整体具有较高的可移植性。本文首先对课题背景及相关的图像处理基本以及无线技术做了基本介绍;其次,通过分析需求,进行系统的总体设计,完成了硬件和软件设计,并对各个功能模块的设计与实现进行了详细阐述,以及对系统做了相关的测试工作。
[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.
