APPARATUS AND METHOD FOR BUILDING A MAP

摘要

PURPOSE: A device and a method for building a map are provided to accurately create a grid map using distance and voltage properties of a distance measuring sensor. CONSTITUTION: A device for building a map comprises an initial map creating unit and a final map creating unit. The initial map creating unit creates first and second maps by selecting different distance-voltage properties of a distance measuring sensor. The final map creating unit creates a third map by combining a part of the first map and a part of the second map. The initial map creating unit comprises a first initial map creating part(401) and a second map creating part(402). The final map creating unit comprises a map combining part(403), an intersection point extracting part(404), and a straight line extracting part(405).
