  • Optical 3D digitizer with enlarged no-ambiguity zone
    Patent number: 7274470
    Abstract: An optical 3D digitizer with an enlarged non-ambiguity zone, comprising a structured light projector for projecting a fringe pattern over a target area, the fringe pattern having a shiftable position over the target area is disclosed. First and second cameras having overlapping measurement fields are directed toward the target area and positioned with respect to the projector to define distinct triangulation planes therewith. The second camera has a larger non-ambiguity depth than the first camera.
