摘要
目的:随着物联网技术发展,智慧交通的应用势必会成为未来整个交通系统的发展方向,其中车联网系统将是关注热点。目前全球已将视频信息大量应用于车车互联、车路互联以及车与管理平台互联中,由于目前尚未有统一的标准规范,不同厂家在视频集成过程中差异较大。因此,相关车联网视频交换系统的测试成为必须。方法:提出一种采用视频流主观评价与传输网络客观测试相结合的方法。结果:验证测试平台的可用性。结论:通过本次研究对车联网视频交换系统的验证测试方法提出新的思路,具备应用价值。
Aims: With the development of internet of things technology, the application of intelligent transportation is bound to become the development direction of the whole transportation system in the future;and the Internet of vehicles(IOV) will be the focus. At present, video information has been widely used in vehicle-vehicle interconnection, vehicle-road interconnection and the interconnection of vehicles and management platform in the world. Because there is no uniform standard specification at present, great differences exist among different manufacturers in the process of video integration. So it is necessary to test the video exchange. Methods: A method combining a subjective evaluation of video stream with an objective test of transmission network was proposed. Results: The availability of the test platform was verified. Conclusions: Through this study, a new idea is proposed for the verification and testing method of the vehicle internet video exchange system, which has application value.
