摘要

Three-dimensional scanning of human bodies or body parts is gaining increasing importance in applications where moving people need to be captured. This could be, for example, people tracking, lip reading, or gesture detection. The advantages of optical 3D sensing in these fields are the contactless measurement and the high potential concerning speed and measurement accuracy. However, classical illumination by structured light may disturb personal activities. 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 illumination system is based on the GOBO principle. Applications interpreting human facial expressions or gestures often require a very short latency time of the data capture because of the necessary subsequent processing of the 3D point clouds. The presented 3D scanner setup achieves a latency time of approximately 100 ms until the 3D data of a 4MPx scan is available. Examples of the acquisition of sequences of face and body scans are given. The measurement accuracy was evaluated by experiments and will be presented and discussed. An outlook of future work is given.
