The invention relates to a vehicle position information real-time tracking method, computer equipment and a storage medium. The method comprises the following steps: acquiring position information of a to-be-locked parking space displayed on a real-time updated map and real-time position information of a vehicle in a world coordinate system; according to the position information of the to-be-locked parking space and the real-time position information of the vehicle, whether a locked parking space exists or not is judged, and the locked parking space is the to-be-locked parking space which is overlapped with the position of the vehicle; if the locked parking space exists, obtaining a relative position distance observation value and a relative position distance prediction value; and performing Kalman filtering according to the relative position distance observation value and the relative position distance prediction value to obtain a relative position distance estimation value, so that the real-time position information of the vehicle is updated according to the relative position distance estimation value. By adopting the method, the accuracy of vehicle position information tracked in real time can be improved.
本申请涉及一种车辆位置信息的实时跟踪方法、计算机设备和存储介质。所述方法包括:获取实时更新的地图上所显示的待锁定车位位置信息和在世界坐标系下的车辆实时位置信息;根据待锁定车位位置信息和车辆实时位置信息,判断是否存在锁定车位,锁定车位为与车辆发生位置重叠的待锁定车位;若存在锁定车位,则获取相对位置距离观测值和相对位置距离预测值;根据相对位置距离观测值和相对位置距离预测值进行卡尔曼滤波,得到相对位置距离估计值,以使车辆实时位置信息根据相对位置距离估计值进行更新。采用本方法能够提高实时跟踪的车辆位置信息精度。
