PROBLEM TO BE SOLVED: To create a map image in which a high-accuracy photographed image is projected on a map.SOLUTION: An image correction device 1 includes an image correction part 22 that receives input of apices of the four corner of a square to a pre-correction image; puts the inside of the square constituted of the apices of the four corners under control of grid lines that partition with vertical lines and transverse lines according to the shape of the square; extracts an area of the pre-correction image put under control of the grid lines; corrects the lengths of the transverse lines of the grid lines in the extracted area to be the same ratio to each other; and takes a post-correction image of a rectangular that is a result of the correction as a plane image on a ground surface to be projected on a map.SELECTED DRAWING: Figure 1 |
