Information processing method and non-transitory computer readable medium

Abstract

An information processing method includes, by a processor, when determining a unit rotation angle in a case where at least one of a capturing device including a camera and a surface light source and an existing object is rotationally moved around a preset rotation axis and a surface of the object is captured from a plurality of directions, setting positional coordinates corresponding to the rotation axis, the camera, the surface light source, and a three-dimensional model of the object in a simulation space, receiving designation of a micro region on the three-dimensional model of the object, calculating, as a first rotation angle with respect to the rotation axis, a positional relationship in which a first illumination light output from a first end point among illumination lights output from the surface light source is specularly reflected by the micro region and is incident on the camera, calculating, as a second rotation angle with respect to the rotation axis, a positional relationship in which a second illumination light output from a second end point among illumination lights output from the surface light source is specularly reflected by the micro region and is incident on the camera, and determining that a difference between the calculated first rotation angle and the calculated second rotation angle is the unit rotation angle.
