Abstract

The invention provides a rendering method and a device based on a three-dimensional model, wherein, the method comprises: acquiring a plurality of two-dimensional face images acquired from a pluralityof angles, and fusing the plurality of two-dimensional face images to generate a skin texture map according to the skin texture map; the two-dimensional facial feature points being obtained by detecting the two-dimensional facial images collected from the front, and the two-dimensional facial feature points are matched with the three-dimensional facial feature points stored in the face image. Ifit is known that there are three-dimensional facial feature points which match the two-dimensional facial feature points successfully, the three-dimensional model corresponding to the three-dimensional facial feature points of the target and the skin texture map are rendered to obtain the rendered three-dimensional face head image. Thus, the rendering efficiency of the three-dimensional model is improved.

Description

technical field [0001] The present application relates to the technical field of portrait processing, in particular to a rendering method and device based on a three-dimensional model. Background technique [0002] With the advancement of computer technology, face-based image processing technology has shifted from two-dimensional to three-dimensional. Because of the stronger sense of reality based on three-dimensional image processing, it has attracted widespread attention. Many smart terminal devices will use three-dimensional face to generate realistic 3D avatars of human faces. [0003] In related technologies, the entire process of generating and rendering a 3D face model is very complicated, and the calculation amount is very large, and the calculation pressure is relatively high. Therefore, a method that can effectively improve the speed of 3D model construction is urgently needed. Contents of the invention [0004] This application aims to solve one of the techni...
