When a road is repaired, it is easy to conduct a survey on a road condition of the road at the time of start of repair. An orthoimage creation method of the present invention includes: a coordinate acquisition step of acquiring three-dimensional coordinates for a plurality of feature points; a photographing step of photographing, by a camera 3, a plurality of photographed images such that each of the plurality of feature points is included in at least two of the photographed images; and an orthoimage creation step of creating an orthoimage with a ground pixel size of 5 mm or less on the basis of the three-dimensional coordinates of each of the feature points acquired in the coordinate acquisition step, and the plurality of photographed images photographed in the photographing step.
