摘　　要：针对车联网图像传输中图像质量与传输实时性之间存在的矛盾,设计一种无线图像传输系统。该系统以S3C2440微处理器为核心,搭载USB数字高清摄像头和无线网卡为硬件平台,以改进实时性内核的Linux操作系统为软件平台,实现无线图像传输。并通过实验验证了传输实时性与传输质量之间的矛盾关系,并提出解决方案。There is a contradiction between quality and real-time in the transmission of images in the internet of vehicle. A wireless image transmission system is designed in this paper. The hardware platform includes S3C2440 microprocessor, a USB digital camera and wireless network card, Linux operat- ing system is employed as the software platform. The experiment results illuminate that the quality of images and the real-time of transmission are oppo- site. Moreover, some solutions are proposed.
