Optics Express
|August 13, 2025
Summary
This study introduces a novel method for dynamic 3D reconstruction using fringe projection profilometry. It accurately measures moving objects by mitigating motion errors and enabling robust absolute phase retrieval.
Area of Science:
- Optical Metrology
- 3D Imaging
- Computer Vision
Background:
- Fringe projection profilometry offers non-contact, accurate 3D measurements.
- Dynamic applications face challenges with pattern requirements and motion-induced phase errors.
Purpose of the Study:
- To develop a motion-induced phase-shifting method for accurate dynamic 3D reconstruction.
- To address limitations of traditional fringe projection profilometry in motion scenarios.
Main Methods:
- Integration of Fourier fringe analysis and speckle correlation-assisted phase matching.
- Estimation of phase shifts and mitigation of phase errors using phase difference analysis and local linear optimization.
- Absolute phase retrieval using triple-view geometric constraints and a single random speckle pattern.
Main Results:
- Effective suppression of motion-induced artifacts in dynamic measurements.
- Accurate 3D reconstruction of objects undergoing non-uniform motion and non-rigid deformation.
- Robust absolute phase retrieval for arbitrary surfaces without prior depth information.
Conclusions:
- The proposed method enhances adaptability and applicability in dynamic measurement scenarios.
- It achieves accurate 3D reconstruction by fully exploiting triple-view information.
- This technique overcomes key limitations of phase-shifting profilometry in dynamic applications.
