Abstract
An evaluation device includes a projector to project a pattern having an edge component onto an object, an imaging device to capture an image of the object, a reflective-property correction unit to correct an amount of change in shape of a virtual image of the pattern reflected in the object, using reflective-property data of a surface of the object, and an evaluation-value calculator to evaluate image clarity of the surface of the object based on the corrected amount of change. A computer-readable non-transitory recording medium storing a program for causing a computer to execute a method. The method includes correcting an amount of change in shape of a virtual image of the pattern reflected in the object based on image data that is obtained by capturing an object onto which a pattern having an edge component is projected, using reflective-property data of a surface of the object.
