A flexible and simplified calibration procedure for fringe projection profilometry

Vargas R.; Marrugo A.G.; Pineda J.; Romero L.A. (SPIE, 2019)

Fringe Projection Profilometry (FPP) is a widely used technique for optical three-dimensional (3D) shape measurement. Among the existing 3D shape measurement techniques, FPP provides a whole-field 3D reconstruction of ...

Developing a Robust Acquisition System for Fringe Projection Profilometry

Pineda J.; Marrugo A.G.; Romero L.A. (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 ...

Noise-Robust Processing of Phase Dislocations using Combined Unwrapping and Sparse Inpainting with Dictionary Learning

Pineda J.; Meza J.; Barrios E.M.; Romero L.A.; Marrugo A.G. (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 ...

Evaluating the influence of camera and projector lens distortion in 3D reconstruction quality for fringe projection profilometry

Vargas R.; Marrugo A.G.; Pineda J.; Meneses J.; Romero L.A. (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 ...

An experimental study on deformation analysis of an indented pipe via fringe projection profilometry and digital image correlation

Forero N.; Marrugo A.G.; Vargas R.; Pineda J.; Useche Vivero, Jairo; Romero L.A. (OSA - The Optical Society, 2018)

We studied the surface displacement of a steel pipe during indentation via Fringe Projection Profilometry and 2D-Digital Image Correlation. Experimental results show that a 3D strain approximation is possible for comparison ...
