Irritation-free pattern projection system for accurate 3D face and body scans

Three dimensional scanning of human bodies or parts of person become more and more a matter of interest especially in medical applications. In this paper a new 3D scanning system is introduced which is absolutely irritation-free based on the structured light illumination by aperiodic sinusoidal fringe patterns in the near infrared range. Hence, it is particularly suitable for continuing human face scanning. The system is based on optical stereo capturing and structured light illumination using the GOBO principle. The measurement principle of the system is explained and examples of face and body scans are given. The measurement accuracy was evaluated by experiments and will be presented and discussed as well as an outlook to future work
