The invention discloses an active vehicle continuous tracking and positioning system and method based on multi-data fusion. A vehicle tracking detection sensor of the system performs tracking detection on a vehicle; collected information is sent to a roadside service platform to be processed, so that vehicle preliminary data information is obtained; the vehicle preliminary data information is fused with regional map data, so that vehicle real-time dynamic information and a unique ID number can be generated; the vehicle enters a license plate snapshot triggering area; a vehicle feature recognition device acquires feature information of the vehicle, sends the feature information to the roadside service platform and calls a vehicle type and three-dimensional contour dimension data corresponding to the feature information, wherein the vehicle type and three-dimensional contour dimension data are pre-stored in a database; and the roadside service platform fuses the real-time dynamic information and the feature information of the vehicle and the Beidou\GPS clock time service information to generate complete vehicle identity information, starts physical space attributes to perform trajectory correction, and continuously outputs vehicle tracking and positioning data. According to the system and method of the invention, the vehicle running on the road can be continuously tracked and positioned without installing positioning equipment on the vehicle.

本发明公开了基于多数据融合的主动式车辆持续跟踪定位系统及方法，所述系统的车辆跟踪检测传感器对车辆进行跟踪检测，采集的信息送至路侧服务平台处理获得车辆初步数据信息，并与区域地图数据进行融合生成车辆实时动态信息及唯一ID身份编号，车辆进入车牌抓拍触发区域，车辆特征识别设备获取车辆的特征信息，送至路侧服务平台，调取预先存在数据库中与之对应的车辆车型及三维轮廓尺寸数据，路侧服务平台将车辆实时动态信息、特征信息与北斗\GPS时钟授时信息进行融合，生成完整的车辆身份信息，启用物理空间属性进行轨迹修正，持续输出车辆跟踪定位数据。本发明实现了不需在车辆上安装定位设备就能对道路上行驶的车辆进行持续跟踪定位。
