Zusammenfassung:	In a road measurement device according to an embodiment, a calibration unit 48 generates formation parameters used for formation of a scale image, from a result of photographing a pattern for calibration by a photographing means 10. An image obtaining unit 44 obtains a road image from the photographing means 10 every predetermined traveled distance. At this time, a coordinate information obtaining unit 56 associates coordinate information obtained from a coordinate obtaining device 12, with the road image. A scale forming unit 50 selects appropriate ones of the formation parameters based on a height and an angle formed by the direction parallel to the road surface which are obtained by a photographing height and angle obtaining unit 46 from a photographing height and angle measuring unit 11, and generates a scale image using those formation parameters.
