An axle number measurement device (30) measures the number of axles of a vehicle (40) that travels on a road (50), and includes: a first communication unit (31) that obtains a captured image (P1) that includes a tire of the vehicle (40); a detector (33) that detects the tire from the captured image (P1); a second communication unit (32) that obtains a depth image (P2) that includes first distances from a predetermined position to the tire and second distances from the predetermined position to a position outside the tire in the captured image (P1), the position outside the tire being the road (50) below the tire; and a measurement unit (34) that measures the number of axles supporting tires in contact with the road (50), based on a continuity between the first distances and the second distances arranged from a position of the tire to the position outside the tire.
