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 …

This paper proposes the development of an automatic fruit harvesting system by combining
a low cost stereovision camera and a robotic arm placed in the gripper tool. The stereovision …

Structured light 3D imaging is often used for obtaining accurate 3D information via phase
retrieval. Single-pattern structured light 3D imaging is much faster than multi-pattern …

In computer vision, two major active range imaging methods have been frequently employed
for rapid and efficient shape recovery:(a) conventional active stereo vision and (b) …

Structured light projection is widely applied in 3D shape measurement. Affected by uneven
illumination, the highlight is produced on high-reflectivity surfaces, and the fringe pattern on …

For fringe projection profilometry, the phase-shifting direction needs to fit the position layout
of a camera and a projector, or the quality of 3D reconstruction will be poor. Two-direction …

In a recent published work we proposed a technique to recover the absolute phase maps of
two fringe patterns with different spatial frequencies. It is demonstrated that a number of …

Surface reflections severely degrade the performance of the structured-light 3D
measurement. In this article, we introduce a novel structured-light 3D measurement …

Collaborative filtering (CF) is one of the most effective techniques in recommender systems,
which can be either rating oriented or ranking oriented. Ranking-oriented CF algorithms …

A 3D shape measurement method in the presence of strong interreflections is presented.
Traditional optical 3D shape measurement methods such as fringe projection profilometry …
