The embodiment of the invention relates to the technical field of intelligent traffic, and provides a target vehicle trajectory virtualization method and device, equipment and a medium, and the method comprises the steps of firstly, determining that the vehicle information of a target vehicle sent by a target radar is received in a current period, and the vehicle information of the target vehicle is not received in a preset duration before the current period; according to the normal azimuth angle of the target radar and the stored vehicle information of the target vehicle, determining the virtual latitude and longitude of the target vehicle in the loss period, wherein the normal azimuth angle is the included angle between the normal of the target radar and the due north direction of the target radar, and the normal is parallel to the road on which the target vehicle runs; and finally updating the track of the target vehicle according to the virtual longitude and latitude. According to the embodiment of the invention, after the target vehicle is determined to be lost, the longitude and latitude positions of the target vehicle during the loss period are determined based on the normal azimuth angle of the radar and the stored vehicle information of the target vehicle, so that the trajectory of the target vehicle can be virtualized, and the integrity of the vehicle trajectory can be improved.

    本发明实施例涉及智能交通技术领域,提供一种目标车辆轨迹虚拟方法、装置、设备及介质,首先确定当前周期接收到目标雷达发送的目标车辆的车辆信息,且在当前周期之前的预设时长内未接收到目标车辆的车辆信息,然后根据目标雷达的法线方位角和存储的目标车辆的车辆信息,确定目标车辆在丢失周期的虚拟经纬度,其中,法线方位角为目标雷达的法线与目标雷达在正北方向之间的夹角,法线与目标车辆行驶的道路平行,最后根据虚拟经纬度更新目标车辆的轨迹。本发明实施例在确定目标车辆丢失后,基于雷达的法线方位角和存储的目标车辆的车辆信息确定出目标车辆在丢失期间的经纬度位置,从而可以虚拟目标车辆的轨迹,进而可以提高车辆轨迹的完整性。
