Abstract
The present application discloses a method and apparatus for positioning a vehicle. An implementation of the method comprises: obtaining laser point cloud data of a laser point cloud collected by a laser radar on a vehicle, and obtaining an initial pose of a center point of the laser radar; calculating a matching probability between projection data corresponding to each sampling pose and map data of a reflected value map respectively; and calculating an optimal pose based on the matching probability between the projection data corresponding to the each sampling pose and the map data of the reflected value map, and determining a position of the vehicle based on the optimal pose.
