摘要

En 中文
基于条纹投影轮廓术(FPP)的三维(3-D)测量在众多工业领域至关重要。然而,高反射工件常导致采集到的条纹图案饱和,致使测量失效。因此,实现便捷、高精度抑制饱和诱发的误差是一项必要要求。本文提出了一种互补相移差分轮廓术(CPDP)以达成此突破。通过利用相移正弦光栅与其对应互补光栅在直流(dc)分量上的对称性,所提出的CPDP能够修复变形条纹中的过饱和区域,并有效抑制饱和诱发的误差。此外,即便部分区域因过度曝光未能完全修复过饱和,通过对应互补修复的变形条纹间的相位平均,饱和诱发的误差仍可得到有效抑制。实验结果表明,所提出的CPDP能够以便捷、高精度的方式抑制饱和诱发的误差,并具有在工业高反射工件三维测量中的良好应用前景。
