Abstract

The invention relates to a three-dimensional face model construction method and device, a computer device and a storage medium, and relates to the technical field of computers. The method comprises the following steps of acquiring a face image; constructing a three-dimensional geometric model according to the face image; filtering the edge of a human face in the human face image to obtain a filtered human face image; extracting a face appearance corresponding to the three-dimensional geometric model from the filtered face image; and constructing a three-dimensional face model corresponding tothe face image according to the face appearance and the three-dimensional geometric model. According to the method, the face segmentation technology and the three-dimensional face model construction technology are combined, the defects at the edge of the face are reduced on the basis that the apparent fidelity of the face is guaranteed, and therefore the three-dimensional face model construction effect is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for constructing a three-dimensional face model. Background technique [0002] With the development of augmented reality (Augmented Reality, AR) technology, 3D face model construction technology is applied to more scenes. [0003] In related technologies, the general model reconstruction method is generally used to realize the construction of a 3D face model, and the general model is modified to match the outline and facial features layout with the input image to be restored, and then assisted by vertex-based difference calculation The appearance information is extracted from the input image to realize the construction of the 3D face model. [0004] In the above-mentioned related technologies, since the number of vertices of the general model used in the process is small, the accuracy of extracting appearance in...
