Abstract: A method is provided that includes: obtaining an initial pose of a vehicle, a multi-modal sensor data of the vehicle, and a plurality of map elements for positioning the vehicle; encoding the multi-modal sensor data to obtain an environmental feature; encoding the plurality of map elements to obtain a map feature; determining, based on the environmental feature and the map feature, a target pose offset for correcting the initial pose; and superimposing the initial pose and the target pose offset to obtain a corrected pose of the vehicle.
