3D reconstruction of the moving object with double-shooting based on phase shifting profilometry

This paper targets a common limitation of phase-shifting profilometry: moving objects violate the static-scene assumption during multi-frame fringe capture. The double-shooting strategy is used to make phase recovery more robust to motion.

Problem setting
Moving-object reconstruction requires phase information that remains consistent across frames. The method uses double-shooting acquisition to reduce phase inconsistency before 3D reconstruction.

Method overview.
Results and impact
The reported experiments evaluate whether the double-shooting strategy improves reconstruction stability for moving targets compared with ordinary phase-shifting acquisition.
