Title: MAP INFORMATION GENERATING DEVICE AND MAP INFORMATION GENERATING METHOD
Abstract:
Provided is technology for identifying mutual correspondence relationships between narrow area maps and wide area maps. A map information generating device is provided with: a narrow area map creation unit for creating narrow area maps using distance information for a plurality of directions obtained using distance sensors; a wide area map acquisition unit for acquiring wide area maps, which are maps of areas wider than the narrow area maps; a matching unit for matching narrow area map positions and angles of rotation on wide area maps obtained by the wide area map acquisition unit; and a narrow area map storage unit for storing information on positions and angles of rotation matched by the matching unit in association with each narrow area map.
