Paper Abstract

A method for real-time three-dimensional (3D) imaging based on Hilbert transform is proposed. Based on the properties of Hilbert transform and De Bruijn sequence, we design an encoding technique based on color fringe patterns to realize 3-D reconstruction of the phase distribution and range images. The calculation of phase map is implemented by using two sinusoidal fringe patterns with phase shifting 0 and π / 2 each other. Two phase-shifted fringe patterns are assigned to the red and blue channel of a color pattern, respectively. The phase unwrapping is accomplished with aid of the De Bruijn sequence pattern stored in the green channel. The experiment results show that the proposed method can not only acquire 3D data in real-time and one-shot fashion, but also obtain high-resolution and high-density range image data without any error propagation.
