In many optical metrology techniques, fringe pattern analysis is the central algorithm for
recovering the underlying phase distribution from the recorded fringe patterns. Despite …

How to obtain object information as rich as possible, with the highest possible speed and
accuracy from recorded optical signals, has been a crucial issue to the pursuit of powerful …

The measuring technique combining a phase-shifting algorithm and Gray-code light has
been widely used in three-dimensional (3D) shape measurement for static scenes because …

In this paper, we propose a high-speed 3D shape measurement technique based on the
optimized composite fringe patterns and stereo-assisted structured light system. Stereo …

The binary defocusing technique has been widely used in high-speed three-dimensional
(3D) shape measurement because it breaks the bottlenecks in high-speed fringe projection …

In order to achieve a higher speed for fringe projection profilometry, we propose a
quaternary gray-code phase unwrapping method using only two defocused binary patterns …

Fourier-transform profilometry (FTP) and phase-shifting profilometry (PSP) are two
mainstream fringe projection techniques widely used for three-dimensional (3D) shape …

For 3D imaging and shape measurement, simultaneously achieving real-time and high-
accuracy performance remains a challenging task in practice. In this paper, a fringe …

The paper presents the automated on-line system for wood logs 3D geometry scanning. The
system consists of 6 laser triangulation scanners and is able to scan full wood logs which …

Phase-measuring deflectometry (PMD)-based methods have been widely used in the
measurement of the three-dimensional (3D) shape of specular objects, and the existing …
