Phase shifting profilometry (PSP) shifts the phase by projecting multiple fringe patterns with different initial phase values. Errors will be introduced when the dynamic object moves among the multiple fringe patterns. This paper presents a new 3D reconstruction method of moving object based on PSP by projecting single fringe pattern. The phase shift is caused by the object movement. Multiple images of the object with movement are captured. The object movement is tracked first; then, the phase variation caused by the movement in the single projected fringe pattern is analyzed and the reconstruction model describing the fringe pattern with movement is given; at last, the phase value is retrieved by utilizing the phase variation caused by the movement. The effectiveness of the proposed method is verified by the simulations and the experiment.

基于相移轮廓法的单条纹运动物体重建

相移轮廓仪 (PSP) 通过投影具有不同初始相位值的多个条纹图案来移动相位。当动态物体在多个条纹图案之间移动时会引入误差。本文提出了一种新的基于PSP的运动目标3D重建方法，通过投影单条纹图案。相移是由物体运动引起的。捕捉物体运动的多幅图像。首先跟踪对象移动；然后，分析了单个投影条纹图案运动引起的相位变化，给出了描述运动条纹图案的重构模型；最后利用运动引起的相位变化反演相位值。通过仿真和实验验证了所提出方法的有效性。
