| 摘 要： | 针对立交区域的监控系统难以准确实时地对车辆进行监控的问题，该文以X3D和XML为基础，提出在真三维环境中进行车辆监控的技术框架。框架集成三维建模技术、X3D技术、差分GPS技术、数据库技术和车辆运动模型，对行驶在立交区域的车辆进行实时监控，准确定位当前车辆的具体路段。实验证明框架是可行的，可用于车辆监控及交通仿真和车辆行为的分析模拟。

| Abstract: | Vehicle monitor is difficult to monitor vehicle runing in continuous Tri-dimensional Traffic Area(TTA). This paper proposes a vehicle monitor framework, which integrates X3D, XML with GPS, and it realizes vehicle movement model, to locate exactly where the cars run in, and to watch cars run in TTA. The framework is proved to be feasible by test done in Guangzhou, which can also be applied in traffic simulation and vehicle behavior analysis. |
