"High-speed 3D imaging with three binary patterns using Hilbert transform," Proc. SPIE, (2019)
The number of patterns used to reconstruct one 3D image is of great importance to high-speed 3D shape measurement. This paper presents a method to reduce the number of patterns by using Hilbert transform with only three binary patterns. Two fringe patterns at different frequencies and one DC component pattern are used for absolute phase retrieval. We directly applied Hilbert transform to the diffe..
