FPP-SLAM: indoor simultaneous localization and mapping based on fringe projection profilometry

open access: yesOptics Express, 2023
Simultaneous localization and mapping (SLAM) plays an important role in autonomous driving, indoor robotics and AR/VR. Outdoor SLAM has been widely used with the assistance of LiDAR and Global Navigation Satellite System (GNSS). However, for indoor applications, the commonly used LiDAR sensor does not satisfy the accuracy requirement and the GNSS ...

High-Accuracy Three-Dimensional Deformation Measurement System Based on Fringe Projection and Speckle Correlation [PDF]

open access: yesSensors, 2023
Fringe projection profilometry (FPP) and digital image correlation (DIC) are widely applied in three-dimensional (3D) measurements. The combination of DIC and FPP can effectively overcome their respective shortcomings. However, the speckle on the surface

Three-Dimensional Shape and Deformation Measurements Based on Fringe Projection Profilometry and Fluorescent Digital Image Correlation via a 3 Charge Coupled Device Camera [PDF]

open access: yesSensors, 2023
We propose a novel hybrid FPP-DIC technique to measure an object’s shape and deformation in 3D simultaneously by using a single 3CCD color camera, which captures the blue fringe patterns and red fluorescent speckles within the same image.

An Efficient 3D Measurement Method for Shiny Surfaces Based on Fringe Projection Profilometry [PDF]

open access: yesSensors
Fringe projection profilometry (FPP) is a widely employed technique owing to its rapid speed and high accuracy. However, when FPP is utilized to measure shiny surfaces, the fringes tend to be saturated or too dark, which significantly compromises the ...
