Abstract

An information management device includes a difference extractor and a determination unit. The difference extractor extracts, as difference information, vehicle peripheral three-dimensional information detected by a vehicle and three-dimensional map information. The determination unit determines whether the extracted difference information is a difference inherent to the vehicle.
