3D human face reconstruction method and device

Abstract

The embodiment of the invention discloses a 3D human face reconstruction method. The method includes the steps that an image for 3D human face reconstruction is obtained, information of a preset number of image feature points serving as 3D human face reconstruction feature points is obtained from the image, and the set of the image feature points is used for reflecting the contour of a human face; a 3D average human face model is acquired; corresponding points of the image feature points in the 3D average human face model are acquired, fitting operation is performed based on the information of the image feature points and the corresponding relation between the image feature points and the corresponding points in the 3D average human face model, deformation model coefficients for 3D human face reconstruction are obtained, the 3D average human face model is corrected according to the deformation model coefficients, and an initial reconstructed 3D human face is obtained; texture coordinates of all points on the initial 3D human face are obtained, and 3D human face reconstruction is achieved. The embodiment of the invention further discloses a 3D human face reconstruction device. Through the 3D human face reconstruction method and device, 3D human face reconstruction can be performed on any image.

Description

technical field [0001] The embodiments of the present application relate to the technical field of information data processing, and in particular to a method and device for 3D face reconstruction. Background technique [0002] In the information processing environment, 3D face reconstruction based on image data has been widely used. The current 3D face reconstruction method is to collect multiple face pictures from multiple angles, and then perform alignment and comprehensive calculation on these face pictures to obtain a 3D face. However, this 3D face reconstruction method has special requirements for the pictures used to reconstruct the object, that is, it can generally only be carried out for pictures containing human faces, and 3D face reconstruction cannot be realized for pictures without human faces, which reduces the user experience. In addition, although this kind of 3D face reconstruction can restore the depth information of the face through multiple pictures, the...

However, this 3D face reconstruction method has special requirements for the pictures used to reconstruct the object, that is, it can generally only be carried out for pictures containing human faces, and 3D face reconstruction cannot be realized for pictures without human faces, which reduces the user experience

In addition, although this kind of 3D face reconstruction can restore the depth information of the face through multiple pictures, the alignment and comprehensive calculation calculations in it are relatively large, and the reconstruction method is extremely cumbersome, which is not conducive to improving the efficiency of 3D face reconstruction.
