The purpose of the present invention is to display an AR image appropriately in a desired position during marker-less type AR display. An information processing device (500) comprises: a model space storage unit (501) for storing a three-dimensional model of a predetermined object existing in a real space; an object information acquiring unit (502) which acquires an image of the object captured by a camera of an augmented reality display device; a relationship identifying unit (503) which, on the basis of a result of comparing the image and the three-dimensional model, identifies a correspondence between a model coordinate system, which is a coordinate system of the model space in which the three-dimensional model exists, and a real space coordinate system, which is a coordinate system of the real space being managed by the augmented reality display device; a transform unit (504) which, using the correspondence, transforms coordinates in the model coordinate system for specifying a display position of the predetermined image into coordinates in the real space coordinate system; and a coordinate notifying unit (505) which notifies the augmented reality display device of the coordinates obtained by transform performed by the transform unit (504).
