A method of 3-D measurement of facial feature points using the head motion

摘要

We propose a method of measuring 3-D coordinates of facial feature points using the head motion. The method uses existing technique to reconstruct 3-D shape of an object. In this technique, the shape is determined from four feature points over three images of the object. We apply this technique in facial image for measurement of facial feature points. In proposed method, because angle of a subject for a camera is determined automatically, it is not necessary to measure angle of direction of the face beforehand. In addition, all 3-D coordinates can be detected correctly in order to supplement it between each image even if one part of feature points hides.
