According to one embodiment, an information processing device according to an embodiment includes an acquisition unit, a detection unit, and a calculation unit. The acquisition unit acquires image data in which an image of a space where a plurality of specific objects exist is captured. The detection unit detects a position and an orientation of each of the plurality of specific objects included in the image data in the space. The calculation unit calculates, for any evaluation target object of the plurality of specific objects, a close-contact evaluation value indicating a degree of close contact between the evaluation target object and one or a plurality of other specific objects other than the evaluation target object among the plurality of specific objects, based on the position and the orientation of each of the plurality of specific objects.
