TY  - JOUR
AB  - We present a near-instant method for acquiring facial geometry and reflectance using a set of commodity DSLR cameras andflashes.  Our  setup  consists  of  twenty-four  cameras  and  six  flashes  which  are  fired  in  rapid  succession  with  subsets  of  thecameras. Each camera records only a single photograph and the total capture time is less than the 67ms blink reflex. Thecameras and flashes are specially arranged to produce an even distribution of specular highlights on the face. We employ thisset of acquired images to estimate diffuse color, specular intensity, specular exponent, and surface orientation at each pointon the face. We further refine the facial base geometry obtained from multi-view stereo using estimated diffuse and specularphotometric information. This allows final submillimeter surface mesostructure detail to be obtained via shape-from-specularity.The final system uses commodity components and produces models suitable for authoring high-quality digital human characters.
