Rotational Motion-Induced Error Compensation for Phase-Shifting Profilometry-Based Eye Reconstruction
Seong-Jin An, Sanghoon Jeon, Yatong An +1
With the proliferation of immersive Head-Mounted Displays (HMDs) for Virtual and Augmented Reality (VR/AR), reliable and high-precision eye tracking has become increasingly importa…
Self-Supervised Dual-Frequency Phase Decomposition for Single-Shot Composite Fringe Projection Profilometry
Jin-Hyuk Seok, Yatong An, Jae-Sang Hyun
Single-shot fringe projection profilometry (FPP) has been actively studied for real-time measurement, dynamic object reconstruction, and motion-sensitive environments. Composite fr…
Contact-Based Fringe Projection Profilometry for High-Resolution 3-D Surface Measurement of Reflective and Transparent Objects
Ingu Yeo, Hyung-Gun Chi, Jae-Sang Hyun
This paper presents a contact-based 3-D surface measurement method based on a Digital Fringe Projection (DFP) system, belonging to the vision-based tactile sensing family pioneered…
Cylindrical Mechanical Projector for Omnidirectional Fringe Projection Profilometry
Mincheol Choi, Gaeun Kim, Jae-Sang Hyun
The demand for 360-degree 3D reconstruction has significantly increased in recent years across various domains such as the metaverse and 3D telecommunication. Accordingly, the impo…
LD-SLRO: Latent Diffusion Structured Light for 3-D Reconstruction of Highly Reflective Objects
Sanghoon Jeon, Gihyun Jung, Suhyeon Ka +1
Fringe projection profilometry-based 3-D reconstruction of objects with high reflectivity and low surface roughness remains a significant challenge. When measuring such glossy surf…
Motion-induced error reduction for high-speed dynamic digital fringe projection system
Sanghoon Jeon, Hyo-Geon Lee, Jae-Sung Lee +4
In phase-shifting profilometry (PSP), any motion during the acquisition of fringe patterns can introduce errors because it assumes both the object and measurement system are statio…
