Abstract

The invention relates to a face three-dimensional reconstruction method and device, an electronic device and a storage medium, and belongs to the technical field of computers. The method comprises thesteps of obtaining an initial three-dimensional face model and a face image; performing face recognition on the face image to obtain face posture data; acquiring projection parameters of equipment ofthe face image and three-dimensional coordinates of all vertexes of the initial three-dimensional face model according to the face posture data, and acquiring two-dimensional coordinates of all the vertexes projected to an imaging plane of the equipment under the posture corresponding to the face posture data of the initial three-dimensional face model; and performing texture mapping processing on the initial three-dimensional face model according to the two-dimensional coordinates of each vertex and the face image to obtain a three-dimensional face model of the face image. According to the method, the reconstruction process is simplified, the calculation amount is small, and the three-dimensional face reconstruction efficiency is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a method, device, electronic equipment and storage medium for three-dimensional reconstruction of a human face. Background technique [0002] In recent years, with the development of augmented reality (Augmented Reality, AR) technology, there is a demand in AR applications to obtain face images from cameras to realize three-dimensional reconstruction of faces. Wherein, the three-dimensional face reconstruction refers to generating a three-dimensional face model based on a two-dimensional image including a face, that is, a face image. [0003] In the related technologies, the 3D morphable model (3D Morphable Model, 3DMM) is generally used to realize the 3D reconstruction of the face. Specifically, a large number of 3D prototype faces are obtained first, and a complex preprocessing process is performed on these 3D prototype faces, and then Statistical modeling of th...
