Repairing Shape-Prior Shortcuts in Long-Range Single-Shot Fringe Projection Profilometry
Adam Haroon, Cody Fleming, Beiwen Li
Single-shot fringe projection profilometry (FPP) networks that regress depth directly can exploit a shape-prior shortcut, recovering depth from object boundaries rather than from fringe phase. On a photorealistic synthetic benchmark (15,600 fringe images, 50 objects at 1.5-2.1 m…
