摘要
基于条纹投影的光学三维测量方法被广泛应用于医疗诊断、工业检测等各行各业中。计算莫尔轮廓术因具有高精度,实时测量能力,且对物体表面反射率不敏感等优点在条纹投影测量轮廓术中占有重要地位。近些年来,许多基于计算莫尔轮廓术的衍生方法被提出,它们不仅实现了测量精度、测量速度的进一步提高,同时也在增强测量不同物体的适应能力。概述了计算莫尔轮廓术基本理论及其衍生方法,并分析了它们的特点,明确了计算莫尔轮廓术的发展动态。
The optical 3D measuring method based on fringe projection is widely used in various industries such as medical diagnosis and industrial testing.Computer-generated Moire profilometry plays an important role in fringe projection profilometry due to its high accuracy,real-time measurement ability,and insensitivity to object surface reflectivity and so on.In recent years,many derivative methods based on computer-generated Moiré profilometry have been proposed,which not only achieve further improvements in both measuring accuracy and measuring speed,but also enhance the adaptability of measuring different types of objects.In this paper,the basic theory and derived methods of computer-generated Moiré profilometry are summarized,and their characteristics are analyzed.The development trends of computer generated Moiré profilometry have been clarified.
