Abstract
A texture evaluation apparatus includes a projector, an imager, and an evaluator. The projector is configured to project a two-dimensional pattern having an edge element onto an object. The imager is configured to capture an image of a surface of the object. The evaluator is configured to calculate an amount of shape change of a virtual image of the two-dimensional pattern in the image, and evaluate texture of the object based on the amount of shape change and sensory evaluation information obtained in advance.
