Spatially Coupled Phase-to-Depth Calibration for Fringe Projection Profilometry 事件

Spatially Coupled Phase-to-Depth Calibration for Fringe Projection Profilometry arXiv:2606.11601v1 Announce Type: new Abstract: 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 achieves high local accuracy, neighboring pixels can acquire markedly different calibration functions even when they observe the same smooth surface, producing spatially inconsistent geometry
