Claim 0:
1. A map generation device comprising:
a probe data acquiring unit configured to acquire a probe data from each vehicle of a plurality of vehicles traveling on a road, the probe data generated based on image data captured by a camera mounted to the corresponding vehicle, the probe data comprising, as shape point sequences, sequences of shape points that indicate marking lines on the road;
a grouping unit configured to categorize the shape point sequences into a plurality of groups for each of the respective plurality of vehicles, each of the plurality cgroups including one or more shape point sequences of marking lines on the road that are acquired by the respective vehicle;
a center point sequence generating unit configured to generate a center point sequence for each marking line based on the one or more shape point sequences included in each of the plurality of groups, wherein generating the center point sequence for each marking line removes information dependent on traveling states of the plurality of vehicles from the shape point sequences of the marking lines; and
a map data generating unit configured to identify the center point sequence for each marking line as a corresponding marking line on a map, and generate map data of the corresponding marking line on the map using the center point sequence, wherein
the map data is delivered to a vehicle, and
the vehicle is controlled using the map data.
