1. A method for measuring a three-dimensional appearance of an object, comprising the steps of: a) capturing a plurality of images of the object from different points of view, wherein a light pattern is projected onto the object from at least one position; b) measuring a plurality of three-dimensional in-sight appearances of the object based on the plurality of images, wherein the plurality of three-dimensional in-sight appearances each correspond to the plurality of images; and c) correcting differences among the plurality of three-dimensional in-sight appearances to synthesize the three-dimensional appearance of the object.
