PROBLEM TO BE SOLVED: To provide a mechanism with which it is possible to measure, by one session of photographing, the distance and planar direction of faces at multiple places of an object to be measured.SOLUTION: The present invention comprises: an image acquisition unit 212 for acquiring an image captured by an image-capturing device 230 in a state in which a projection pattern formed by arranging in plurality a set of geometric figures provided at narrower intervals than a prescribed value at intervals wider than the prescribed value is projected to an object K to be measured; a geometric figure detection unit 213 for detecting the geometric figures in the projection pattern from the image; a geometric figure set determination unit 214 for determining a set of geometric figures from the geometric figures detected by the geometric figure detection unit 213; a distance calculation unit 216 for calculating a distance from prescribed reference coordinates on a face of the object K to be measured, to which the geometric figures detected by the geometric figure detection unit 213 are projected; and a planar direction calculation unit 217 for calculating, on the basis of the distance calculated by the distance calculation unit 216, a planar direction on the face of the object K to be measured, to which the set of geometric figures is projected. |
