基于深度学习的条纹到条纹变换的动态三维测量

Dynamic 3-D measurement based on fringe-to-fringe transformation using deep learning

摘要:

条纹投影轮廓术(FPP)在动态三维面形测量中的作用日益重要。在FPP中,在进行形状轮廓测量之前,需要对被测物体的相位进行反演。然而,传统的相位恢复技术往往需要大量的条纹,这可能会产生运动引起的误差为动态对象。提出了一种基于深度学习的相位恢复技术,利用端到端的深度卷积神经网络将单个或两个条纹转换为相位恢复所需的条纹。当物体的表面位于一个有限的深度,所提出的网络只需要一个单一的条纹作为输入,否则需要两个条纹在一个不受限制的深度。首先对相位恢复技术进行了理论分析,然后通过数值模拟和实验验证了该技术在动态三维测量中的适用性。

英文摘要:

Fringe projection profilometry (FPP) has become increasingly important in dynamic 3-D shape measurement. In FPP, it is necessary to retrieve the phase of the measured object before shape profiling. However, traditional phase retrieval techniques often require a large number of fringes, which may generate motion-induced error for dynamic objects. In this paper, a novel phase retrieval technique based on deep learning is proposed, which uses an end-to-end deep convolution neural network to transform a single or two fringes into the phase retrieval required fringes. When the object's surface is located in a restricted depth, the presented network only requires a single fringe as the input, which otherwise requires two fringes in an unrestricted depth. The proposed phase retrieval technique is first theoretically analyzed, and then numerically and experimentally verified on its applicability for dynamic 3-D measurement.
