Abstract
An information processing device for extracting a difference between a reference map and an input map, the information processing device comprising: a control unit that divides each region of a reference map and an input map into a branch region where a branch of a road or a lane exists, and a non-branch region other than the branch region; determine a branch region and a non-branch region of the input map corresponding to the branch region and the non-branch region of the reference map based on an overlap degree of the branch region of the reference map and the branch region of the input map, and determine a graph editing path in which an editing cost determined by a predetermined criterion is minimized for each of the corresponding regions; and output the graph editing path for multiple corresponding regions as a difference between the reference map and the input map.
