Background intensity removal in Fourier transform profilometry: A comparative study
(OSA - The Optical Society, 2016)We study the removal of the background intensity of fringe patterns via Empirical Mode Decomposition and the Hilbert Transform. Simulation results show that the latter provides a suitable background compensation with minimal ... -
Developing a Robust Acquisition System for Fringe Projection Profilometry
(Institute of Physics Publishing, 2019)Since Fringe Projection Profilometry (FPP) is an intensity-based coding strategy, it is prone to improper optical setup arrangement, surface texture and reflectance, uneven illumination distribution, among others. These ... -
Evaluating the influence of camera and projector lens distortion in 3D reconstruction quality for fringe projection profilometry
(OSA - The Optical Society, 2018)We study the influence of geometric distortions of the camera and projector lenses on 3D reconstruction quality for fringe projection profilometry. Experimental results on real objects and their 3D models show the accuracy ... -
Fringe quality map for fringe projection profilometry in LabVIEW
(Sociedad Espanola de Optica, 2018)The phase retrieval process is mainly affected by local shadows, irregular surface brightness and fringe discontinuities. To overcome these problems, image-processing strategies are carried out such as binary masks, ... -
Microscopic shape from focus using white light interferometric fringes
(OSA - The Optical Society, 2018)In this work we study the use of a focus measure to improve the 3D reconstruction of low reflectivity microscopic samples using white light interference microscopy. Simulation and experimental results show the improved ... -
Noise-Robust Processing of Phase Dislocations using Combined Unwrapping and Sparse Inpainting with Dictionary Learning
(Institute of Electrical and Electronics Engineers Inc., 2019)The problem of phase unwrapping from a noisy and also incomplete wrapped phase map arises in many optics and image processing applications. In this work, we propose a noise-robust approach for processing regional phase ... -
Robust 3D surface recovery by applying a focus criterion in white light scanning interference microscopy
(OSA - The Optical Society, 2019)White light scanning interference (WLSI) microscopes provide an accurate surface topography of engineered surfaces. However, the measurement accuracy is substantially reduced in surfaces with low-reflectivity regions or ... -
What is the best triangulation approach for a structured light system?
(Cartagena de Indias, 2020-05-18)It has become customary to calibrate a camera-projector pair in a structured light (SL) system as a stereo-vision setup. The 3D reconstruction is carried out by triangulation from the detected point at the camera sensor ...
