Embodiment 1

[0037] Such as figure 1 As shown, the present invention provides a kind of three-dimensional human face reconstruction method, comprises the steps:

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

[0039] S2: In the case that the color image and the depth image are aligned, extract the two-dimensional coordinates of the marker points of the target face in the color image through deep learning, and according to the color image and the depth image The corresponding relationship obtains the three-dimensional coordinates of the marker 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 a threshold value of the depth value, so as to filter out the target face from the original target face three-dimensional point cloud model of the ...

Abstract

The invention provides a three-dimensional face reconstruction method and system, and the method comprises the steps: obtaining a color image and a depth image of a target face under at least two visual angles, and judging whether the color image and the depth image are aligned or not; acquiring three-dimensional coordinates of the mark points of the target face and an original target face three-dimensional point cloud model of the target face; screening out a point cloud model of the target face; carrying out point cloud rough matching to obtain a roughly registered target face three-dimensional point cloud model; performing accurate registration to obtain an accurately registered target face three-dimensional point cloud model; fusion deduplication, gridding and grid fairing are carriedout, and then performing texture enhancement to obtain an optimized target face grid model; and making a texture map, and performing texture mapping on the optimized target face grid model to obtain afinal target face grid model. And the reconstructed face model is higher in quality and is closer to a real face effect.

Description

technical field [0001] The invention relates to the technical field of image processing, 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 fields such as 3D space mapping, 3D reconstruction of objects, intelligent human-computer interaction, and VR. Reconstructing a 3D face model based on face depth data is a hot topic in current research. [0003] However, in the prior art, face templates are established through machine learning, which lacks authenticity. Contents 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 that the present invention adopts is as follows: [0006] A three-dimensional...
