PROBLEM TO BE SOLVED: To make it possible to calculate the three-dimensional coordinates of a feature point with high accuracy.SOLUTION: An image selection unit 12 selects a first selection image from a plurality of image-captured images. The image selection unit 12 also selects a second selection image from among a plurality of subsequent images image-captured thereafter, on the basis of an inter-image-capture position distance between the image-capture position of the first selection image calculated on the basis of the position information of a marker 22 in the first selection image and the image-capture position of each of the plurality of subsequent images calculated on the basis of the position information of the marker 22 in each of the plurality of subsequent images, and the number of corresponding feature points that correspond between the feature point extracted from the first selection image and the feature point extracted from each of the plurality of subsequent images. A coordinate calculation unit 13 calculates the three-dimensional coordinates of a plurality of corresponding feature points on the basis of the two-dimensional coordinates of each corresponding feature point in each of the first selection image and the second selection image.SELECTED DRAWING: Figure 1
