Abstract
A method and apparatus for constructing a map for a mobile robot to be able to reduce a data amount and increase an approach speed. The method includes: searching for a plurality of feature data occupying an arbitrary space by scanning a surrounding environment of the mobile robot; performing quadtree segmentation on first feature data of the plurality of feature data to generate a plurality of first node information as a result of the quadtree segmentation; determining a position of second feature data of the plurality of feature data with respect to the first feature data; and performing a neighborhood moving algorithm for generating a plurality of second node information of the second feature data according to the position of second feature data by using the plurality of first node information.
