<p>A three-dimensional scanner is provided. The scanner includes a projector that emits a light pattern onto a surface. The light pattern includes a first region having a pair of opposing saw-tooth shaped edges and a first phase. A second region is provided in the light pattern having a pair of opposing saw-tooth shaped edges and a second phase, the second region being offset from the first region by a first phase difference. A third region is provided in the light pattern having a third pair of opposing saw-tooth shape edges and having a third phase, the third region being offset from the second region by a second phase difference. A camera is coupled to the projector and configured to receive the light pattern. A processor determines three-dimensional coordinates of at least one point on the surface from the reflected light of the first region, second region and third region.</p> |
