Abstract

The invention discloses a 3D face image reconstruction method, a 3D face image reconstruction device, a three-dimensional face image reconstruction hardware device and a computer-readable storage medium. The 3-D face image reconstruction method comprises the steps of acquiring real 2D face key points and predicting 2D face key points; iteratively optimizing the expression coefficients by solving the first loss function which is composed of the real 2D face key points, the predicted 2D face key points and the preset additional regular constraint terms. The expression coefficients are used to represent the real state of the face, and the 3D face image is reconstructed according to the expression coefficients. The expression coefficients are optimized iteratively by the first loss function which is composed of the predicted two-dimensional face key points and the preset additional regular constraint terms to constrain the expression coefficients, so that the expression coefficients can represent the real state of the face, and the 3D face image reconstruction technology can be optimized to obtain the real state of the face.

Description

technical field [0001] The present disclosure relates to the technical field of three-dimensional reconstruction, in particular to a three-dimensional facial image reconstruction method, device and computer-readable storage medium. Background technique [0002] With the improvement of equipment computing power and the development of 3D technology, 3D face has attracted more and more attention from academia and industry, and its application fields have become more and more extensive. 3D reconstruction technology is the source technology of 3D technology. Traditional 3D reconstruction technology relies on high-precision laser radar or multi-view 3D reconstruction. Although these methods are reliable, lidar has high requirements for equipment, and multi-view 3D reconstruction relying on feature point matching is quite time-consuming. Therefore, restoring a 3D model from a single image has become a research hotspot. 3D face image reconstruction can be used in face changing, exp...
