Ray-based phase error correction for miniaturized DOE projector-based FPP under single-directional hyperbolic projection
Seung-Jae Son, Yatong An, Jae-Sang Hyun
Fringe Projection Profilometry (FPP) systems using miniaturized DOE pro-jectors often suffer from severe phase artifacts due to nonlinear projection characteristics and limited pat…
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…
DepthTCM: High Efficient Depth Compression via Physics-aware Transformer-CNN Mixed Architecture
Young-Seo Chang, Yatong An, Jae-Sang Hyun
We propose DepthTCM, a physics-aware end-to-end framework for depth map compression. In our framework of DepthTCM, the high-bit depth map is first converted to a conventional 3-cha…
Quasi-calibration method for structured light system with auxiliary camera
Seung-Jae Son, Yatong An, Jae-Sang Hyun
The structured light projection technique is a representative active method for 3-D reconstruction, but many researchers face challenges with the intricate projector calibration pr…
