Fringe Projection Profilometry Performed with a Light Field Camera

A method of fringe projection profilometry combined with light field camera recording is introduced to achieve high dynamic range 3D imaging. The modulated fringe phases can be detected from multiple directions with light field camera. And employing a novel ray-based calibration approach, phase-height mapping coefficients and height coordinates along each ray direction can be accurately determined independently. The experimental results illuminate that this multidirectional depth estimation can achieve high dynamic range 3D imaging effectively.
