The invention discloses a memory parking positioning method and a related device, and relates to the technical field of automatic driving. In the application, a server obtains initial pose information of a target vehicle in a global coordinate system in real time, and obtains a conversion relationship between the global coordinate system and a local coordinate system corresponding to each piece of initial pose information based on a historical pose information set associated with a target map; and the initial pose information under the global coordinate system is converted to be under the local coordinate system, corresponding target pose information is obtained, and finally, initial positioning of the target vehicle is obtained based on the target pose information at multiple moments. Thus, by establishing the conversion relation between the global coordinate system and the local coordinate system, the pose information under the global coordinate system is converted into the pose information under the local coordinate system, even under the condition that no GPS signal exists, the accurate real-time pose can be provided for HPA positioning, and the efficiency and accuracy of HPA tracing parking are improved.

    本申请公开了一种记忆泊车定位方法及相关装置,涉及自动驾驶技术领域。本申请中,服务器实时获取目标车辆在全局坐标系下的初始位姿信息,并基于目标地图关联的历史位姿信息集,获取各初始位姿信息各自对应的全局坐标系与局部坐标系之间的转换关系,将全局坐标系下的初始位姿信息转换至局部坐标系下,获得相应的目标位姿信息,最后基于多个时刻下的目标位姿信息获得目标车辆的初始化定位。这样,通过建立全局坐标系和局部坐标系之间的转换关系,将全局坐标系下的位姿信息转换至局部坐标系下,即使在无GPS信号的情况下,也能为HPA定位提供精确的实时位姿,提高了HPA寻迹泊车的效率和精确度。
