In traditional laser-based 3D measurement technology, the width of the laser stripe is uncontrollable and uneven. In addition, speckle noise in the image and the noise caused by mechanical movement may reduce the accuracy of the scanning results. Thi

A surface with large reflection variations represents one of the biggest challenges for optical 3D shape measurement. In this work, we propose an alternative hybrid 3D shape measurement approach, which combines the high accuracy of fringe projection

In sinusoidal fringe projection profilometry (FPP), many factors are known to improve measurement accuracy. However, the parameters of the projected fringe pattern, such as modulation and pitch, are the most basic factors. Some empirical principles h

For disparity information acquisition tasks, phase-shift profilometry can achieve high disparity accuracy, but it is a stereo matching technique based on phase unwrapping. The phase unwrapping depends on the fringe pattern of multifrequency. Recent w

In this paper, we present a flexible 3D scanning system based on a MEMS scanner mounted on an industrial arm with a turntable. This system has 7-degrees of freedom and is able to conduct a full field scan from any angle, suitable for scanning object

Line structure light measurement needs accurate mechanical movement device and high -frame-rate camera, which is difficult to realize. We propose a high-speed full-field profilometry to solve these difficult ies, using coded laser strips projected by
