Pixel-wise rational model for a structured light system

This Letter presents a novel structured light system model that effectively considers local lens distortion by pixel-wise rational functions. We leverage the stereo method for ini-tial calibration and then estimate the rational model for each pixel. Our proposed model can achieve high measure-ment accuracy within and outside the calibration volume, demonstrating its robustness and accuracy. (c) 2023 Optica Publishing Group
