Published in 2020 at "Applied optics"

DOI: 10.1364/ao.383602

Abstract: The key to accurate 3D shape measurement in fringe projection profilometry (FPP) is the proper calibration of the measurement system. Current calibration techniques rely on phase-coordinate mapping (PCM) or back-projection stereo vision (SV) methods. PCM… read more here.

Published in 2023 at "Optics express"

DOI: 10.1364/oe.480503

Abstract: Single-shot high-accuracy reconstruction of three-dimensional (3D) objects plays an essential role in many fields. Wavelet-based fringe projection profilometry (WFPP) is a popular single-shot imaging method due to its multiple-resolution analysis and non-contact property. However, the… read more here.
