Optimal frequency selection for accuracy improvement in binary defocusing fringe projection profilometry.
TL;DR: In this paper , an optimal frequency selection approach was proposed by analyzing the phase error distribution under different defocusing degrees, and the associated relationship with fringe frequency, system defocusing degree, noise, and other influencing factors was established.

High-Accuracy Calibration of High-Speed Fringe Projection Profilometry Using a Checkerboard
TL;DR: In this paper , a hybrid method with improved accuracy and operability, based on a unique back-projection and nonlinear epipolar sampling analysis, is presented. But it suffers from limited accuracy and complexity.

Intensity diffusion: a concealed cause of fringe distortion in fringe projection profilometry
TL;DR: In this article , an intensity diffusion model is established for quantifying the diffused intensity in each pixel, and an intensification correction algorithm is presented to remove the diffuse intensity from the fringe images and correct the fringe distortion.

Fourier-transform method of fringe-pattern analysis for computer-based topography and interferometry
TL;DR: In this article, a fast Fourier transform method of topography and interferometry is proposed to discriminate between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour generation techniques.

Satellite radar interferometry: Two-dimensional phase unwrapping
TL;DR: In this paper, an approach to 'unwrapping' the 2 pi ambiguities in the two-dimensional data set is presented, where it is found that noise and geometrical radar layover corrupt measurements locally, and these local errors can propagate to form global phase errors that affect the entire image.

Fourier transform profilometry for the automatic measurement of 3-D object shapes
Mitsuo Takeda,Kazuhiro Mutoh +1 more
TL;DR: A new computer-based technique for automatic 3-D shape measurement is proposed and verified by experiments that has a much higher sensitivity than the conventional moire technique and is capable of fully automatic distinction between a depression and an elevation on the object surface.
