Abstract
A method and an apparatus for correcting deformation of a digital map for a vehicle, includes loading a related part from the digital map; determining whether the related part includes road coordinate information in a first zone and road coordinate information in a second zone, wherein the road coordinate information in the first zone is associated with a first Cartesian coordinate system and the road coordinate information in the second zone is associated with a second Cartesian coordinate system; transforming the road coordinate information in the second zone to the first Cartesian coordinate system, if the related part includes the road coordinate information in the first zone and the road coordinate information in the second zone; and generating a corrected map by combining the road coordinate information in the first zone and the transformed road coordinate information in the second zone; wherein the first Cartesian coordinate system is the coordinate system of the vehicle for processing the road coordinate information.
