Abstract：
 The present invention belongs to the field of computer-aided human face image re-construction technology. The present invention features that human face as model establishing object is first photographed with two, one upper and one lower, stere ovideo cameras to obtain video sequence from the front to the side of the face with unchanged expression; the precise posture parameters in different times are then obtained via autoamtic posture estimating algorithm; after the initiation of model and posture, 3D information are extracted separately from two types of 2D threads including one stereo reconstruction type of the image and the other matching and correcting type of model projection contour and image contour; and the 3D face model is finally established.
