摘要: 为适应综合交通运输网络多元化业务的发展, 实现交通信息传输的兼容性、标准化与适应性, 研究了异构信息系统的Web、CORBA、QT跨平台处理技术与H.264视频转码机理, 分析了基于ITS条件的跨平台异构操作系统数据及图像传输的基本要求, 提出了基于B/S的可伸缩SVG路况地图Web浏览界面, C/S的ViewBox视窗与H.264转码技术的交通信息监控技术。应用结果表明: 新技术的应用满足ITS的地域广与实时性高的要求, 提高了ITS图像跨平台传输的质量与系统的鲁棒性。Abstract: To adapt the development of diversified business in integrative transportation network and realize the compatibility, standardization and adaptability of traffic information transmission, Web, CORBA and QT cross-platform technologies in heterogeneous information system and H.264 video trans-coding principle were studied, the basic transmission requirements on data and images of ITS were analyzed, a traffic information surveillance technology was proposed, and the Web browser interface of scalable SVG map based on B/S mode and the ViewBox window based on C/S mode and H.264 video trans-coding technology were taken as its base. Application result shows that the new technologies can satisfy the requirements of wide area and real time of ITS, and can improve the cross-platform transmission quality of ITS images and system robustness.
