MAP UPDATING METHOD AND COMPUTER PROGRAM RECORDED ON RECORDING MEDIUM TO EXECUTE THE SAME

Proposed is a map updating method for updating a map using data acquired from other sensors for regions with low global positioning system (GPS) signal sensitivity on a precision road map generated based on GPS information. The method may include loading, by a data generating device, a reference map generated based on location information acquired by a global positioning system (GPS) device and first point cloud data acquired from a first light detection and ranging (LiDAR) and updating, by the data generating device, the reference map based on second point cloud data acquired from a second LiDAR mounted on a vehicle traveling on a path of the reference map.
