An information processing device (200A, 200B, 200C) according to the present invention is provided with a control unit (220, 220B, 220C). The control unit (220, 220B, 220C) acquires an image of an object captured by a sensor. The captured image is an image that is obtained from reflection of light radiated on the object from a plurality of light sources arranged at different positions. The control unit (220, 220B, 220C) extracts a flat area from the captured image on the basis of luminance values in the captured image. The control unit (220, 220B, 220C) calculates shape information about the surface shape of the object on the basis of the flat area of the captured image and information about the sensor. |
