The invention discloses a method for removing a multipath false target in a tunnel based on a multi-radar video, and the method achieves the all-weather and high-reliability detection of a vehicle target through the fusion of millimeter-wave radar and visual information. A system track ID number and visual information are continued through target matching in an overlapping area of adjacent radars, and whether the target is a false target caused by a multipath effect is judged by utilizing whether the visual information exists on the target, so that the multipath target is filtered; finally, the continuous cross-radar continuous tracking, positioning and monitoring of the same vehicle target in the whole road continuously covered by a plurality of radars are realized, the information of the tracked target is ensured to be unchanged all the time, and the real-time position, speed and whole-course track of the vehicle and the characteristic information of the license plate, the model, the color and the like of the vehicle are accurately displayed. And meanwhile, false targets generated due to a multipath effect in the tunnel are filtered out.

    本发明公开了基于多雷达视频去除隧道中多径虚假目标的方法,通过对毫米波雷达和视觉信息进行融合从而获得更全面的目标信息,实现对车辆目标的全天候和高可靠性检测;通过相邻雷达重叠区域目标匹配将系统航迹ID号和视觉信息进行延续,同时利用视觉信息是否存在于目标上来判断是否为多径效应导致的虚假目标,以此将多径目标进行滤除;最终实现对被多个雷达连续覆盖的整条道路内的同一车辆目标连续的跨雷达间的持续跟踪定位与监视,并保证被跟踪的目标信息始终不变,精准展示车辆实时位置、速度、全程轨迹及车辆的车牌、车型、车辆颜色等特征信息,同时滤除隧道中因多径效应而产生的虚假目标。
