Fringe projection technique is one of the most widely used techniques for three-dimensional (3D) shape and deformation measurements by Wang Z, Nguyen DA, Barnes JC (2010) Some practical considerations in fringe projection profilometry. Opt Lasers Eng 48:218–225. Generally, it is a difficult task to conduct high-speed measurement with this technique because the speed of projecting fringes is restricted by the projector. In addition, the technique usually employs multiple-shot method such as the phase-shifting scheme, which can considerably cut down the measurement speed. To make the technique suitable for high-speed measurement, single-shot approach is normally adopted; however, a number of problems can arise, such as those associated with phase calculation, phase unwrapping, shadow and occlusion, discontinuity, multiple objects, accuracy, etc. In this paper, we propose some practical considerations to cope with the limitations in existing single-shot fringe projection technique for high-speed 3D shape and deformation measurements. Experimental supports are presented.
