    Abstract: In accordance with an aspect of the present disclosure, there is provided a method of updating a high definition map. The method comprises, acquiring two-dimensional images at a plurality of different locations by using a camera mounted on a vehicle; checking a moving trajectory of the camera for acquiring the two-dimensional images; generating a local landmark map by estimating, based on surface information of a road in the high definition map, a three-dimensional position of a landmark for a lane marking around the moving trajectory of the camera; and updating the high definition map based on the local landmark map.
