Claim One:
1. A method of reconstructing a three-dimensional (3D) face from images captured by a plurality of stereo cameras, the method comprising: simultaneously acquiring n images of a target by controlling the plurality of stereo cameras in response to an image acquirement request, wherein n denotes a natural number equal to or greater than 4; extracting n face regions from the n images, respectively; reconstructing a viewpoint-based face image based on the n face regions; determining an estimated error point in the viewpoint-based face image based on a 3D coordinate value or a disparity value of a point in the viewpoint-based face image that exceed respective predetermined error ranges; removing the estimated error point from the viewpoint-based face image; and performing matching processing on the viewpoint-based face image from which the estimated error point is removed, wherein each stereo camera comprises a plurality of digital single-lens reflex (DSLR) cameras.
