Face measuring based on active & passive vision fusion

Three-dimensional (3D) face recognition, as an important tool of modern authentication, is being causing concerns interests by more and more researcher. In this paper, a 3D measuring device for Chine-se adult´s facial data based on Gray coding structured light and stereo vision was designed. The measuring model was built based on the Measuring principle. After errors analyzing, the error of image coordinate extracting is determined as the largest error source for measuring result. The results of experiments show that this design is feasible, and the acquirement of the 3D data of human face is achieved. The reconstruct surface is similar in the visual effects, and the surface of human face could be display smoothly and detail.
