Sensor-Informed Per-Point Covariance for Structured-Light 3D Imaging
Sehoon Tak, Jae-Sang Hyun
Per-point uncertainty models are important in structured-light 3D reconstruction for probabilistic registration, fusion, and quality assessment. In practice, however, point-cloud c…

Spatially Coupled Phase-to-Depth Calibration for Fringe Projection Profilometry
Sehoon Tak, Jae-Sang Hyun
In fringe projection profilometry (FPP), depth is commonly recovered by fitting a phase-to-depth relation independently at each camera pixel. Although such pixel-wise calibration a…

High-Precision 6DOF Pose Estimation via Global Phase Retrieval in Fringe Projection Profilometry for 3D Mapping
Sehoon Tak, Keunhee Cho, Sangpil Kim +1
Digital fringe projection (DFP) enables micrometer-level 3D reconstruction, yet extending it to large-scale mapping remains challenging because six-degree-of-freedom pose estimatio…
