Abstract

The present invention is suitable for the image processing technology field. The present invention provides a three-dimensional face reconstruction method and system. The method and system comprise: a three-dimensional imaging units are respectively arranged at left and right two sides of face in the same mode; the multi-mode relation between the 3D cloud coordinates collected by the 3D imaging units and the corresponding phase according to the result of the binocular calibration, and the transformation relation between the 3D cloud coordinates collected by the 3D imaging units is determined; the 3D imaging unit collects the image sequences at two sides of the face, and the absolute phase of the image sequence is obtained; by employing the multi-mode relation, the absolute phase of the image sequences is mapped to the 3D point cloud coordinates; and according to the transformation relation, the 3D point cloud coordinates of the 3D imaging units are uniformed in the whole coordinate system. The rapid face 3D reconstruction is realized, the processing efficiency of the face 3D reconstruction is improved.

Description

technical field [0001] The invention belongs to the technical field of computer graphics, and in particular relates to a three-dimensional face reconstruction method and system. Background technique [0002] With the development of computer graphics technology, 3D face modeling has become a research hotspot in the field of computer graphics. 3D face modeling has been gradually applied to many fields such as virtual reality, film and television production, medical plastic surgery, face recognition, game entertainment, etc., and has strong application value. [0003] In the process of 3D face modeling, optical 3D imaging technology is widely used by technicians because of its advantages of non-invasiveness, fast data acquisition speed, and high measurement accuracy. Among them, the 3D imaging technology based on fringe projection has obtained basic For mature applications, however, the data measurement speed of this method is low, causing the efficiency of 3D face modeling to...
