A system, method, and apparatus for vehicle positioning. The vehicle may include a data processing system ("DPS") including one or more processors and a memory. The DPS may receive sensor data from a sensor of the vehicle. The DPS may identify a historical road spectrum of a ground surface for a first location of the vehicle. The DPS may generate a current road spectrum of the ground. The DPS may determine a lateral deviation of the vehicle. The DPS may determine a match between the historical road spectrum and the current road spectrum at a second location aligned with the lateral deviation. The DPS may provide an indication of a current location of the vehicle as the second location.
一种用于车辆定位的系统、方法和设备。所述车辆可包含数据处理系统(“DPS”),其包含一个或多个处理器和存储器。所述DPS可从所述车辆的传感器接收传感器数据。所述DPS可针对所述车辆的第一位置标识地面的历史道路谱。所述DPS可生成所述地面的当前道路谱。所述DPS可确定所述车辆的横向偏离。所述DPS可确定与所述横向偏离对准的第二位置处所述历史道路谱与所述当前道路谱之间的匹配。所述DPS可提供所述车辆的当前位置的指示作为所述第二位置。
