Apparatus to capture three-dimensional images of a head comprises a plurality of image capturing device modules, each module comprises a plurality of image-capturing devices; and a rigid support structure supporting the plurality of image capturing device modules to define a space wherein an image of the head may be disposed. The rigid support structure supports all of the modules in predetermined relationship to each other and to the space. The rigid support structure further supports the modules in positions such that each module is positioned to capture a group of first images of a corresponding surface portion of a head disposed within the space such that each group of first images captured by the corresponding module captures a substantially different surface portion of the head disposed within the space.
