Zusammenfassung: | Provided are a map generation system and a mobile object configured so that the map accuracy of an occupancy grid map can be ensured while a memory capacity and an arithmetic processing load can be reduced. The map generation system includes a storage (27) configured to store, as detection information, a detection value obtained for each detection unit by a detection device (4) in chronological order, a map producer (23) configured to produce the occupancy grid map based on the detection information stored in the storage (27) and cause the storage (27) to store the occupancy grid map, and an influence ratio calculator (24) configured to calculate an influence ratio for the occupancy grid map for each piece of detection information stored in the storage (27). The map producer (23) sorts the detection information based on the influence ratio calculated by the influence ratio calculator (24) to produce the occupancy grid map. |
