Abstract:
This road surface state estimating method is for estimating the state of a road surface on which a vehicle (100) travels, wherein an observation area (R1) of a road surface (10) is determined by using image information obtained by capturing an image of the road surface (10) with a camera (101), first road surface information about the observation area (R1) is acquired from the image information, second road surface information about the observation area (R1) is acquired from sensing information obtained by detecting the state of the road surface (10) with a road surface sensor (104), and the road surface state of the observation area (R1) is estimated on the basis of the first road surface information and the second road surface information.
