An ortho-image creation method includes: first photographing of photographing a road; second photographing of photographing an area covered by the obstacle from an altitude lower than the obstacle by a second photographing apparatus, and obtaining a plurality of second photographed images; first coordinate acquisition of acquiring three-dimensional coordinates; second coordinate acquisition of acquiring three-dimensional coordinates of a second feature point located in the area covered by the obstacle and included in at least two of the plurality of second photographed images; and ortho-image creation of creating a corrected ortho-image obtained by correcting at least a part of the area covered by the obstacle in the road surface to an area not covered by the obstacle, on the basis of the plurality of first photographed images, the plurality of second photographed images, the three-dimensional coordinates of the first feature point, and the three-dimensional coordinates of the second feature point.
