Claim Text:
1. A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute a road surface inspection process comprising: detecting an abnormal region on a road surface from the road surface on an image stored in an image storage that stores therein an image in which a road surface of a road is captured by an imaging device mounted on a vehicle in association with a captured time of the image; first determining whether the abnormal region overlaps a wheel trace stored in a trace storage that stores a trace on the image captured by the imaging device, along which wheels of the vehicle are expected to pass on the road surface, or a trace along which the wheels of the vehicle passes on the road surface; and when the abnormal region is determined to overlap the trace of the wheels, second determining whether an acceleration is outside a predetermined acceleration range, the acceleration being an acceleration at a measurement time corresponding to the captured time of the image in which the abnormal region overlaps the trace of the wheels among accelerations stored in an acceleration storage that stores therein an acceleration measured during driving on the road surface by an acceleration sensor mounted on the vehicle in association with the measurement time of the acceleration.
