高速公路视频监控在iOS移动终端平台上的实现

The Implementation of Expressway Video Surveillance on iOS Mobile Terminal Platform

视频监控是高速公路应急指挥系统中必不可少的组成部分,随着计算机、网络、图像处理与传输技术的快速发展,尤其是移动3G通信网络的广泛覆盖以及各种智能终端平台的不断成熟,为其从传统的有线网络监控转移到无线移动监控提供了更为经济便捷的实现途径。研究了移动视频监控的关键技术,借助于公共的3G网络服务接口,针对苹果公司iOS平台iPad移动终端设备,实现了无线通信方式下基于实时地理信息的高速公路视频监视系统。详细介绍了该系统的组成框架及关键技术的解决方案。在此基础上展望了未来现场应急指挥中视频交互的作用及应用前景,指出了移动智能终端上视频应急指挥的发展方向。

As an indispensable part of expressway emergency decision systems, with the rapid development of computers, net-works, image processing and transmission technologies, especially, the wide coverage of 3G public mobile communication net- work and continual development of various smart terminal platforms, video surveillance has got a more economical and convenient approach to switching from traditional wired network surveillance to wireless mobile surveillance. This paper discusses some key technologies of mobile video surveillance, and the implementation of the GIS-based expressway video surveillance sys- tem under the wireless communication environment based on the access to 3G public network service interface and utilization of iPad mobile terminal devices running the Apple iOS system. The system framework and the key technical measures are detailed. This paper also looks into the value and application prospect of interactive video in future spot-emergency decision making and points out the developing direction of the visual emergency decision making with mobile smart terminals.
