Commercially available 3D image acquisition techniques include Stereo Vision, Structured Light, and ToF. CW ToF imaging systems offer excellent mechanical robustness, no baseline requirement, high effective depth image resolution, low computational cost, and simultaneous IR ambient light invariant intensity capture (Active Brightness). In a CW ToF
