Two new 3D scanning setups for the fast acquisition of sequences of moving persons based on near-infrared structured light projection are introduced. Both systems consist of a pair of stereo cameras and a projection unit and are working in the near-infrared range (illumination wavelength is over 780 nm) which is absolutely irritation-free for the observed person. The first system is based on the so- called GOBO projector and the second system uses a multi-aperture-projection unit consisting of ten projecting components. Measurements of 3D sequences of moving persons and examples of changing facial expressions are given in order to show the power of the setups. The results obtained by the use of the different projection systems are compared concerning measurement accuracy and robustness.
