Abstract

The present invention is applicable to the technical field of image processing, and provides a three-dimensional face reconstruction method and system, comprising: setting three-dimensional imaging units with the same configuration on the left and right sides of the human face to be tested; , establishing a polynomial relationship between the three-dimensional point cloud coordinates collected by the three-dimensional imaging unit and the corresponding phase according to the result of the binocular positioning, and determining the transformation relationship between the three-dimensional point cloud coordinates collected by the two three-dimensional imaging units; Collecting the image sequences on the left and right sides of the measured face by the three-dimensional imaging unit to obtain the absolute phase of the image sequence; using the polynomial relationship, mapping the absolute phase of the image sequence to three-dimensional point cloud coordinates; According to the transformation relationship, the three-dimensional point cloud coordinates of the three-dimensional imaging unit are unified into the global coordinate system. The invention realizes the fast three-dimensional reconstruction of the human face and improves the processing efficiency of the three-dimensional reconstruction of the human face.

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...
