This image correction device is provided with: a direction vector correction unit (3) which corrects vectors using imaging position information on the basis of the difference between known three-dimensional coordinates of a ground control point (GCP) that are acquired by an information acquisition unit (1) and the coordinates of the GCP in selected image data; an orthoimage generation unit (4) which orthorectifies pieces of image data on the basis of the selected image data and the corrected vectors, thereby generating orthoimages; a shift amount calculation unit (5) which calculates an amount of shift between the generated orthoimages; and a GCP information correction unit (7) which corrects the coordinates of the GCP in the selected image data on the basis of the calculated amount of shift. |
