1. An image display method comprising:
a storage step in which a processor causes a storage medium to store three-dimensional data generated on the basis of two or more two-dimensional images of a subject,
wherein the three-dimensional data include three-dimensional coordinates of two or more points of the subject and a first camera coordinate, the first camera coordinate indicating three-dimensional coordinates of a first camera that acquires each of the two or more two-dimensional images, the first camera coordinate being associated with each of the two or more two-dimensional images;
a first selection step in which the processor selects a reference image that is a two-dimensional image of the subject;
a second selection step in which the processor selects at least one of the two or more two-dimensional images as a selected image on the basis of the reference image;
an estimation step in which the processor estimates, on the basis of the first camera coordinate associated with the selected image, a second camera coordinate that is previously unknown, the second camera coordinate indicating three-dimensional coordinates of a second camera that acquired the reference image; and
a display step in which the processor;
projects two-dimensional coordinates of one or more points of a region of the subject seen in the reference image onto a three-dimensional model of the subject to estimate corresponding one or more coordinates on the three-dimensional model;
generates a shape image showing the three-dimensional model of the subject seen from a viewpoint different from the second camera coordinate, the one or more coordinates on the three-dimensional model estimated from the two-dimensional coordinates of the one or more points of the region of the subject seen in the reference image projected onto the three-dimensional model; and
displays the shape image on a display.
