摘要

近期研究集中于提升长距离单次拍摄条纹投影轮廓测量（FPP）技术，该技术用于精确的3D形状测量。研究强调了逆平方强度衰减和缺乏条纹阶数信息所带来的挑战，这可能导致测量不准确。为了解决这些问题，研究人员引入了PhiCalNet，这是一种采用机械解释性和保形不确定性量化的新方法。该创新方法显著降低了物体的平均绝对误差，从14.54毫米改善至4.46毫米，展示了在各种应用中实现更精确3D轮廓测量的潜力。

Recent research has focused on enhancing long-range single-shot fringe projection profilometry (FPP), a technique used for precise 3D shape measurement. The study highlights the challenges posed by inverse-square intensity falloff and the lack of fringe-order information, which can lead to inaccuracies in measurements. To address these issues, the researchers introduced PhiCalNet, a novel approach that employs mechanistic interpretability and conformal uncertainty quantification.
