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 application relates to the technical field of computers, in particular to a method, a device, computer equipment and a storage medium for constructing a three-dimensional face model. technical background [0002] With the development of Augmented Reality (AR) technology, 3D face model construction technology has been applied to more scenes. [0003] In related technologies, the general model reconstruction method is generally used to construct the 3D face model. By modifying the general model to make its outline and facial features layout match the input image to be restored, and then extracting the apparent information from the input image by vertex difference operation, the 3D face model is constructed. [0004] In the above-mentioned related technologies, the accuracy of apparent information extraction is low due to the small number of vertices of the general model used in the process, which leads to defects in the face edge region and affects the co...
