Embodiment 1

[0037] like figure 1 As shown, the present invention provides a three-dimensional face reconstruction method, comprising the following steps:

[0038] S1: Acquire a color image and a depth image of a target face from at least two viewing angles, and determine whether the color image and the depth image are aligned;

[0039] S2: Under the condition that the color image and the depth image are aligned, extract the two-dimensional coordinates of the landmark points of the target face in the color image through deep learning, The corresponding relationship obtains the three-dimensional coordinates of the landmark points of the target face;

[0040] S3: Estimate the position of the target face according to the three-dimensional coordinates of the landmark points of the target face and set the threshold of the depth value, so as to screen out the target face from the original target face three-dimensional point cloud model of the target face The point cloud model, wherein, the ori...

Abstract

The present invention provides a three-dimensional face reconstruction method and system. The method includes: acquiring a color image and a depth image of a target face from at least two viewing angles, and judging whether the color image and the depth image are aligned; acquiring the target The three-dimensional coordinates of the landmark points of the face and the original target face three-dimensional point cloud model of the target face; screen out the point cloud model of the target face; perform rough matching of the point cloud to obtain the rough registered three-dimensional point cloud model of the target face ; Perform accurate registration to obtain a precisely registered 3D point cloud model of the target face; perform fusion deduplication, meshing and grid smoothing, and then perform texture enhancement to obtain an optimized target face mesh model; make textures Figure, the optimized target face mesh model is textured to obtain the final target face mesh model. The reconstructed face model is of higher quality and closer to the real face effect.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a three-dimensional face reconstruction method and system. Background technique [0002] With the rapid development and popularization of depth cameras, the 3D data of objects can be obtained more and more quickly and accurately, which makes depth cameras rapidly applied in the fields of 3D space mapping, 3D reconstruction of objects, intelligent human-computer interaction, and VR. Reconstructing a 3D face model based on the depth data of the face is a hot research direction at present. [0003] However, in the prior art, face templates are established through machine learning, which lacks authenticity. SUMMARY OF THE INVENTION [0004] In order to solve the problems in the prior art, the present invention provides a three-dimensional face reconstruction method and system. [0005] The technical scheme adopted in the present invention is as follows: [...
