METHOD FOR RECOGNIZING LANE-LEVEL VEHICLE LOCATION INFORMATION BASED ON LIDAR MAP MATCHING, RECORDING MEDIUM AND DEVICE FOR PERFORMING THE METHOD

摘要

A method for recognizing a lane-level vehicle location information based on a lidar map matching comprises the steps of: extracting a part of global map data related to the current location of a vehicle of reference global map data stored based on global positioning system (GPS) data installed in the vehicle; obtaining, in real time, local map data related to a location in a current lane of the vehicle under driving from a sensor installed in the vehicle; performing a map matching for the part of global map data and the local map data through rotation and shifting; and correcting the location and direction of the vehicle obtained from the GPS signal based on the result of the map matching. Accordingly, the location and traveling direction of the vehicle can be more accurately measured using a lidar positioning without expensive equipments.;COPYRIGHT KIPO 2018
