Phase measuring profilometry is a method of structured light illumination whose three-
dimensional reconstructions are susceptible to error from nonunitary gamma in the …

In order to overcome the limitations of the sequential phase-shifting fringe pattern
profilometry for dynamic measurements, a color-channel-based approach is presented. The …

A new method of 3D measurement based on a digital light processing (DLP) projector is
presented. The projection model of the DLP projector is analyzed, and the relationship …

For three-dimensional shape measurement, phase-shifting techniques are widely used to
recover the objective phase containing height information from images of projected fringes …

Gamma distortion is a dominant error source of phase measuring profilometry. It makes a
single frequency for the ideal sinusoidal waveform an infinite width of spectrum. Besides, the …

This paper proposes a rapid method to detect aero-engine blade form, according to the
characteristics of an aero-engine blade surface. This method first deduces an inclination …

Fringe projection profilometry is widely used in different areas; it has the benefit of retrieving
full-field height information from a single or multiple fringe patterns with high precision and …

Digital sinusoidal phase-shifting fringe projection profilometry (DSPFPP) is a powerful tool to
reconstruct three-dimensional (3D) surface of diffuse objects. However, a highly accurate …

We present an algorithm for estimating the color demixing matrix based on the color fringe
patterns captured from the reference plane or the surface of the object. The advantage of this …

We report a sinusoidal fringe projection system based on superluminiscent diode (SLD) as a
broad-band light source in conjunction with an acousto-optic tunable filter (AOTF) as …
