Abstract

Diffuse objects have suitable optical properties for accurate three-dimensional reconstruction by fringe projection profilometry. In contrast, shiny objects, such as glossy plastic items and metallic workpieces, are difficult to reconstruct due to image saturation. In this paper, the recursive structure of the hierarchical multi-frequency fringe projection profilometry is exploited to prevent saturation by a feedback loop. Novel functions for saturation, low-modulation, and grating intensity correction, suited to adjust the projector pixels inducing saturation, are proposed. The usefulness of the proposal is verified experimentally, confirming the high performance of the proposed phase feedback approach for the reconstruction of shiny objects.

漫反射物体具有合适的光学特性，可通过条纹投影轮廓仪进行精确的三维重建。相反，光亮的物体，如光亮的塑料制品和金属工件，由于图像饱和而难以重建。本文利用分层多频条纹投影轮廓测量法的递归结构，通过反馈回路防止饱和。本文提出了新的饱和、低调制和光栅强度校正函数，适用于调整引起饱和的投影像素。实验验证了该建议的实用性，证实了所建议的相位反馈方法在重建闪亮物体方面的高性能。

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
