In the paper one face 3D-shape measurement based on infrared structure light is suggested, via projecting infrared stripe on face, the 3D information of face is gotten adopting Fourier transform profilometry. The principle,system framework and experiment result are presented. The method has not violation to detected objects, also meets the needs of special environment for covertmeasurement,and will have obvious applied foreground in the domain of 3D face recognition.
