Abstract

An embodiment of the present application provides an image data processing method, device, device, and medium, the method including: acquiring a first three-dimensional object model, the first three-dimensional object model is a three-dimensional model carrying a target texture map; acquiring a second three-dimensional object model , the second 3D object model is a 3D model that does not carry the target texture map, and the shape difference between the object shape in the first 3D object model and the object shape in the second 3D object model satisfies the shape similarity condition; obtain the second 3D object The projection point of the vertex in the model in the first three-dimensional object model, according to the projection point, determine the migration texture coordinates of the vertices in the second three-dimensional object model; obtain the texture data corresponding to the migration texture coordinates in the target texture map, according to the migration texture coordinates The texture data and the second 3D object model are used to generate a target 3D model carrying the texture data. By adopting the embodiment of the present application, the texture transfer 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 ...

AI Technical Summary

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
