| 摘 要： | 将广义时间相位解包裹方法和影栅方法相结合,设计实现了一种基于时间相位解包裹方法的三维形貌测量系统。首先采集投影物体表面上的调制影栅图案,然后使用时间相位解包裹方法获取影栅图被调制前后的解包裹相位差图,据此重建物体三维形貌。给出了相位求解的原理及实现流程,进行了实验测试。实测结果表明,系统能够高效率、高精度地重建物体表面形貌。

| Abstract: | A three-dimensional shape measurement system is designed and it combines the generalized temporal phase unwrapping method and fringe pattern. Firstly, fringe patterns modulated by object surface are captured. Then, the temporal phase unwrapping method is used to get the unwrapped phase difference. Finally, the 3D profile is reconstructed according to the phase difference. The method of phase unwrapping is introduced. Experiment results shows that the system is capable of high efficiency and high precision reconstruction of object three-dimensional profile. |
