摘要

基于条纹投影的三维形貌测量技术，已经在提升测量精度、提高测量速度、扩大测量景深、增加测量场景适应性等方面被进行了大量研究。但由于条纹投影技术本身的原理限制，仅利用传统条纹投影方法难于实现准确的对应点匹配。而依赖于对应点追踪的形变测量和应变分析可以进一步分析物体的运动状态、材料特性以及结构力学参数，在运动仿生学、材料力学、结构力学等诸多领域中起着不可或缺的作用。本文回顾了近年来新发展出的一系列基于条纹投影的三维形貌与形变测量技术，论述了学者们如何在条纹投影系统上一步步实现从简单刚体位移的测量到复杂、精细结构的形变测量和应变分析。分析了此类技术在测量完整度、分辨率以及计算效率上相比于已有形变测量技术的优势，给出了此技术所面临的挑战和潜在发展动向。

Abstract

3D shape measurement based on fringe projection profilometry （FPP） has been extensively studied in terms of improving measurement accuracy， accelerating the measurement speed， expanding the measurement depth， and increasing the adaptability of the measurement scene. However， due to the principle limitation of FPP， it is difficult to achieve accurate matching of corresponding points using the traditional FPP method. The deformation measurement and strain analysis relying on the corresponding point tracking can be further performed to analyze the motion state of the object， material properties and structural mechanics parameters， which plays an indispensable role in many fields such as motion bionics， material mechanics， and structural mechanics. Therefore， this paper reviews a series of newly developed 3D shape and deformation measurement techniques based on FPP in recent years， and discusses how scholars have gradually realized the measurement from simple rigid body displacement measurement to complex and fine structure deformation measurement and strain analysis based on a FPP system. Finally， the advantages of this technique in measurement integrity， resolution and computational efficiency compared with the existing deformation measurement technique are analyzed， and the challenges and potential development trends of this technique are given.
