Researchers have developed RACE-FPP, a novel AI-assisted pipeline for enhancing the characterization of Fringe Projection Profilometry (FPP) systems. This method integrates deep learning-based corner detection into the standard camera characterization workflow, addressing challenges like lens blur and varied target orientations that degrade accuracy. By analyzing how localization errors propagate through the entire FPP characterization chain, RACE-FPP significantly reduces camera reprojection error from 1.237 to 0.259 pixels and improves projector reprojection error by approximately 50%. This leads to more reliable industrial FPP measurements and enhanced geometric accuracy in 3D reconstructions. AI
