The information processing deviceincludes an acquisition unitA, a structural feature point extraction unitA, a common coordinate system transformation unitA, and a structural feature point integration unitA. The acquisition unitA is configured to acquire captured images Im generated by plural image acquisition devicesand positional relation information Ip indicative of a positional relation among the plural image acquisition deviceThe structural feature point extraction unitA is configured to extract, from each of the captured images Im, intra-image coordinate values Pi for structural feature points, which are structural feature points of a target structure of observation through a display device, the display device displaying a virtual object superimposed on a view. The common coordinate system transformation unitA is configured to convert, based on the positional relation information Ip, the intra-image coordinate values Pi for each of the structural feature points extracted from each of the captured images Im into individual coordinate values Pc indicating coordinate values in a common coordinate system which is a common three-dimensional coordinate system. The structural feature point integration unitA is configured to determine, for each of the structural feature points, a representative coordinate value Pcr in the common coordinate system based on the individual coordinate values Pc in the common coordinate system.

Information processing device, control method, and storage medium

The information processing deviceincludes an acquisition unitA and a structure matching unitA. The acquisition unitA is configured to acquire, from a captured image captured by a photographing unitA of a display device configured to display a virtual object superimposed on a view, multiple combinations of classification information of a structural feature point that is a feature point, in structure, of a target structure and position information of the structural feature point. The structure matching unitA is configured to generate coordinate transformation information by matching structure data 'Ds' with the multiple combinations, the structure data Ds including information associated with a position and a class of each of structural feature points of the target structure, the coordinate transformation information relating to a coordinate transformation between a first coordinate system that is a coordinate system referred to by the display device and a second coordinate system that is a coordinate system adopted in the structure data Ds.
