1. A matching apparatus comprising a processor that is configured to:
extract at least one reference part that is common in a first image and a second image, from each of the first image and the second image, the first image and the second image being images of a photographic subject at different imaging times;
derive first position information indicating a relative position of at least one abnormal part specified in the first image, relative to the at least one reference part in the first image;
derive second position information indicating a relative position of at least one abnormal part specified in the second image, relative to the at least one reference part in the second image;
derive, on the basis of the first position information and the second position information, a linear distance between the abnormal part included in the first image and the abnormal part included in the second image; and
associate, on the basis of the linear distance between the abnormal parts respectively included in the first and second images, the abnormal part included in the first image and the abnormal part included in the second image with each other.
