Construction method and device of three-dimensional face model, storage medium and terminal

Abstract

The invention discloses a three-dimensional face model construction method and device, a storage medium and a terminal, and the method comprises the steps: obtaining N groups of scanning data of an actor, the N groups of scanning data respectively corresponding to N expressions, and the N expressions at least comprise neutral expressions; respectively constructing N point cloud grid models according to the N groups of scanning data, wherein the N point cloud grid models at least comprise neutral expression point cloud grid models corresponding to neutral expressions; generating a neutral expression face grid according to the obtained initial face grid and a neutral expression point cloud grid model; combining the obtained basic expression grid templates to obtain a composite expression initial template; for each other expression, obtaining a composite expression grid according to other expression point cloud grid models corresponding to the other expressions, the neutral expression point cloud grid model and the composite expression initial template; and performing expression splitting on the composite expression grid to obtain a real basic expression grid template of the actor. According to the scheme, the three-dimensional face model construction efficiency can be improved.

Description

Technical field [0001] Embodiments of the present invention relate to the field of three-dimensional face, in particular, to a three-dimensional face model, a construction method, a storage medium, and a terminal. Background technique [0002] The fabrication of a real face has always been a difficult problem in the three-dimensional (3D) field. At present, it is usually built by the model master and the facial layout, etc., which requires a good artwork with a good artwork. It is often a deep understanding of the human anatomy. In addition, the production cycle is often relatively long, causing the construction of a three-dimensional face model. The efficiency is low. Inventive content [0003] The technical problem solved by the embodiment of the present invention is how to improve the construction efficiency of the three-dimensional face model, and shorten the construction time. [0004] In order to solve the above technical problem, the embodiment of the present invention pr...
