Problems solved by technology
When the number of 3D face models to be constructed is too large, it means that a corresponding template model needs to be designed for each existing face model in order to migrate the textures in the existing face models to the template model, In turn, the efficiency of texture transfer is too low

Embodiments of the invention provide an image data processing method and device, equipment and a medium. The method comprises the following steps: acquiring a first three-dimensional object model which is a three-dimensional model carrying a target texture map; acquiring a second three-dimensional object model which is a three-dimensional model not carrying the target texture map, wherein a difference between an object shape in the first three-dimensional object model and an object shape in the second three-dimensional object model meets the condition of shape similarity; acquiring projectionpoints of vertexes in the second three-dimensional object model in the first three-dimensional object model, and determining migration texture coordinates of the vertexes in the second three-dimensional object model according to the projection points; and acquiring texture data corresponding to the migration texture coordinates in a target texture map, and generating a target three-dimensional model carrying the texture data according to the texture data corresponding to the migration texture coordinates and the second three-dimensional object model. By adopting the embodiments of the invention, the texture migration efficiency of the three-dimensional model can be improved.
Description
technical field [0001] The present application relates to the technical field of the Internet, and in particular to an image data processing method, device, equipment and medium. Background technique [0002] With the maturity of 3D (three-dimensional) scanning technology and the advancement of face recognition technology, the superiority of 3D face recognition compared to traditional two-dimensional face recognition, especially in computer vision, animation painting design, medicine, security, machine learning and other fields. The template model (without texture) can be texture transferred through the existing face model (with texture) to construct a new 3D face model library. [0003] In the existing model texture migration process, it is required to have a corresponding relationship between the vertices of the face model and the vertices of the template model (for example, the vertices of the template model are obtained by reducing the dimensionality of the vertices of ...
