Abstract

The present invention is applicable to the field of image processing technology, provides a three-dimensional facial reconstruction method and system comprising: arranging three-dimensional imaging units with the same configuration on both of left side and right side of a target human face; implementing binocular calibration to the three-dimensional imaging units; establishing a polynomial relation between 3D point cloud coordinates captured by the three-dimensional imaging units and corresponding phases according to a result of the binocular calibration and determining the transformation relation among the 3D point cloud coordinates captured by two three-dimensional imaging units; capturing image sequences on the left side and right side of the target human face by the three-dimensional imaging units to obtain absolute phases of the image sequences; mapping the absolute phases of the image sequences to the 3D point cloud coordinates by using the polynomial relationship; unifying the 3D point cloud coordinates of the three-dimensional imaging units to a global coordinate system according to the transformation relationship. The present invention implements a rapid three-dimensional reconstruction of a face and improves the processing efficiency of three-dimensional facial reconstruction.
