Position coordinate derivation device, position coordinate derivation method, position coordinate derivation program, and system

Abstract

An object of the present disclosure is to make it possible to ascertain coordinates of facility. A processor obtains two or more captured images of a facility and an object (S101), obtains position coordinates and an actual size of the facility and a size of the object from a database (S104), calculates a distance from each camera that has captured the two or more images to the object using a relationship between a distance from each camera that has captured the two or more images to the facility and a magnification with respect to the actual size of the facility on the two or more images (S108), and derives position coordinates of the object using the calculated distance (S109).

Dependencies are inferred from the claim text.
