Abstract
The map information processing device includes a processor. The processor that extracts difference data by comparing a movement track image based on individual movement tracks of a plurality of moving bodies with an image in a scalar form based on vector data that is different from the movement track image; and The processor that decides through machine learning whether the difference data corresponds to a road shape change.
Claims14
A map information processing device comprising
- a processor configured
- to acquire probe data for each of a plurality of moving bodies;
- to generate a movement track image in a scalar form on the basis of vector probe data acquired for each of the plurality of moving bodies;
- to convert map information that includes information indicating a position and shape of a road from a vector form to a scalar form;
- to extract difference data indicating a difference between the movement track image and a map image included in the map information converted into a scalar form;
- and
- to decide through machine learning whether the difference data corresponds to a road shape change.
A map information processing method wherein a computer performs the processes of:
- acquiring probe data for each of a plurality of moving bodies;
