The invention discloses a vehicle positioning system and method based on multi-sensor information fusion in a tunnel scene, and the method comprises the steps: arranging RFID readers at the top of a tunnel at an entrance of the tunnel and two side walls in the tunnel, and arranging LED lamps at the top of the tunnel; vehicle positioning in a tunnel scene is realized by utilizing visual image processing, radio frequency identification (RFID) and visible light communication (VLC) multi-sensor information fusion; when the number of vehicles in the tunnel is too large, a driver can adjust a driving route in time according to information displayed by the display module, and the problem of traffic congestion is effectively avoided. If it is detected that the position of a certain vehicle in the tunnel is not updated for a long time, an alarm is given immediately to remind a worker to check the vehicle condition; the position information of the vehicles in the tunnel can be transmitted to the data processing module of the cloud platform through the wireless transmission module, and when problems occur, early warning information is displayed on the vehicle-mounted display in time, a driver is reminded to decelerate, and danger is avoided; the system has the characteristics of clear purpose, simple structure, less hardware equipment, high precision, good reliability, low cost and the like.
一种隧道场景下基于多传感器信息融合的车辆定位系统及方法,通过在隧道入口处的隧道顶部和隧道内部的两侧墙壁布置RFID阅读器,隧道顶部布置LED灯,利用视觉图像处理、射频识别RFID和可见光通信VLC多传感器信息融合实现隧道场景下的车辆定位;在隧道内车辆数目过多时,驾驶员可根据显示模块呈现的信息,及时调整行车路线,有效避免交通拥挤问题;检测到隧道内某车辆长时间位置不更新,则即时报警,提醒工作人员查看该车辆情况;且隧道内车辆的位置信息可以通过无线传输模块传输给云平台的数据处理模块,出现问题时及时将预警信息在车载显示器显示,提醒驾驶员减速,避免发生危险;目的明确,结构简单,硬件设备少,具有精度高、可靠性好、成本低等特点。
