New neural network architecture improves 3D depth estimation

Researchers have developed PhiCalNet, a novel neural network architecture designed to improve depth estimation in single-shot fringe projection profilometry. Unlike previous methods that could exploit shape-prior shortcuts, PhiCalNet outputs a wrapped-phase representation that is mapped to depth through a fixed differentiable calibration layer, architecturally removing the shortcut. This new approach significantly reduces object mean absolute error by 3.3x, confining errors to the phase wrap discontinuity. AI
