In the last few years, phase shifting profilometry has gradually applied High speed real-time three-dimensional measurement for dynamic scenes. The motion of an object in multiple phase shifted fringes not only causes position mismatch, but also introduces additional phase shift, making traditional Phase Shifting Profilometry unable to accurately measure moving objects. This article centering on moving objects, proposes a two-step high frame rate 3D reconstruction method utilizing dual sampling. Sampling two moving object stripe images within one stripe projection cycle, analyzing the impact of object motion on phase under the same projected stripes and between different projected stripes, establishing stripe description equations for different situations, and finally achieving three-dimensional reconstruction of moving objects based on two stripe images with known ambient light. The experimental results show that this method not only achieves three-dimensional measurement of moving objects, but also effectively improves the reconstruction frame rate.
