AI Technical Summary
Technical Problem
Existing map generation devices require significant time to produce highly accurate map data due to the need to store and process transient difference data, which can be inefficient.
Method used
A map generation device that corrects probe data based on differences between basic shape information from a base map and probe shape information estimated from vehicle behavior, allowing direct merging of corrected probe data onto the base map without storing transient data.
Benefits of technology
This approach improves map accuracy and reduces the time required to generate highly accurate maps by avoiding the need to store transient data, enabling rapid and precise map updates.

Abstract
A map-generating device configured to generate a probe map (Mp) from probe data collected by a vehicle, and comprising a processor (102) configured to: obtain the probe data collected while the vehicle travels on a road; generate the probe map by combining the probe data with a base map (Mb) containing at least basic shape information about the shape of the road; and correct the probe data based on a difference in shape between the basic shape information and probe shape information about the shape of the road, estimated from probe behavior data relating to vehicle behavior in the probe data. Generating the probe map includes merging the corrected probe data onto the base map.
