Abstract: An information processing apparatus that is communicable with an in-vehicle device includes a detection section to detect a change of a specific feature at every predetermined timing based on probe information, the specific feature being a feature on a road and used in control of automated driving. The detection section includes a first calculation section to calculate a first index based on the probe information; a second calculation section to calculate a second index based on the probe information; and a comparison section to detect a change of the specific feature by comparing the first index and the second index.

Abstract: A map points-of-change detection device includes: a camera capturing an image of an area around a vehicle; a bird's-eye-view transformation section transforming the image into a bird's-eye view image; a map storage portion storing a road map including a road surface map; a collation processing section determining whether a point of change in the road surface map exits, the point of change being a position at which a change has occurred on an actual road surface; and a collation region identification section that determines a region for collation in a width direction of the vehicle from the bird's-eye view image.
