Fringe projection profilometry is widely used for three-dimensional (3D) measurements. System calibration is crucial to fringe projection systems, since it determines how the phase is converted into 3D geometry. Many methods and studies on calibration have been presented in the last few years. However, a comparative overview on the accuracy and the implementation details is still lacking. In this work, we present a review of some of the most used calibration methods. First, the basic principles are reviewed. Then, both quantitative and qualitative comparative experiments are implemented to show the advantages and constraints of each method. Further, a number of factors that may affect the performance of the calibration are discussed. Sample codes are available for better comprehension and a quick start of these methods.

条纹投影轮廓仪广泛用于三维（3D）测量。系统校准对于条纹投影系统至关重要，因为它确定了如何将相位转换为3D几何形状。在最近几年中已经提出了许多校准方法和研究。然而，仍然缺乏对准确性和实施细节的比较概述。在这项工作中，我们将介绍一些最常用的校准方法。首先，回顾基本原理。然后，进行定量和定性的对比实验，以显示每种方法的优点和局限性。此外，讨论了可能影响校准性能的许多因素。示例代码可用于更好地理解和快速启动这些方法。
