Fringe projection profilometry is widely used for three-dimensional (3D) measurements.
System calibration is crucial to fringe projection systems, since it determines how the phase …

Fringe projection techniques are very popular among the several profilometry methods
proposed in literature. One of their main advantages is that most of them require one image …

Structured light vision systems have been successfully used for accurate measurement of
3D surfaces in computer vision. However, their applications are mainly limited to scanning …

Micro-Electro-Mechanical System (MEMS) scanning is increasingly popular in 3D surface
measurement with the merits of the compact structure and high frame-rate. In this paper, we …

In fringe projection profilometry (FPP), the geometric calibration of the projector is based
mainly on the assumption of the anti-camera model. But that model is not adequate for 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 …

Two major methods for 3D reconstruction in fringe projection profilometry, phase-height
map** and stereovision, have their respective problems: the former has low-flexibility in …

In this work we present a phase to (x, y, z)-coordinates transformation method for the
calibration of a fringe projection profilometer. Our technique is divided in two parts:(1) phase …

In Fourier-transform profilometry (FTP), the height information is extracted from the phase
distribution through triangulation; the relationship between the phase and height distribution …

To be able to perform inline inspection of complex geometries, which exhibit for example
undercuts or internal structures, a new endoscopic micro fringe projection system has been …
