The invention discloses a holographic vehicle track correction algorithm for data abnormity of road sensing equipment, and solves the problem that the authenticity and reliability of a holographic digital road vehicle track are reduced due to disordered point clouds and abnormal positions of millimeter-wave radar in the prior art. Comprising the following steps: S1, acquiring position points of each exit lane of a current intersection, and numbering the exit lanes; s2, calculating the current target exit lane of each vehicle according to the existing track of each vehicle in the current intersection; s3, calculating the position relationship among the current vehicles in the intersection; and S4, on the basis of the position relationship among the vehicles, deviation correction based on the target exit lane is carried out on the vehicles in the intersection in sequence, and vehicle track deviation correction is realized. When the original trajectory data of the road sensing device deviates abnormally, the vehicle trajectory in the holographic digital road is rectified in time, and the authenticity and reliability of the vehicle trajectory in the holographic digital road are effectively improved.

    本发明公开了一种针对道路感知设备数据异常的全息车辆轨迹纠偏算法,克服现有技术中存在的毫米波雷达点云杂乱和位置异常导致全息数字道路车辆轨迹真实性和可靠性降低的问题,包括以下步骤:S1:获取当前路口各出口道车道的位置点,并对出口道车道进行编号;S2:根据当前路口内各车辆的已有轨迹,计算各车辆当前的目标出口道车道;S3:计算路口内当前各车辆之间的位置关系;S4:基于各车辆之间的位置关系,对路口内的车辆依次进行基于目标出口道车道的纠偏,实现车辆轨迹纠偏。当道路感知设备的原始轨迹数据发生异常偏移时,对全息数字道路中的车辆轨迹进行及时纠偏,有效提升全息数字道路车辆轨迹真实性和可靠性。
