Abstract

The invention provides an efficient and automatic hair matching head form generation method. The method comprises the following steps: S1, defining vertex data set structures of a basic head model, a deformed head model, a basic hair model and a deformed hair model; S2, loading the basic head model and the basic hair model, traversing all vertexes in the basic hair model, taking all vertex positions in the basic hair model as starting points, and performing ray detection on the central point of the basic hair model to obtain a vertex UV2 data set of the basic hair model; S3, generating a spatial position map Dmap of the deformation head model; and S4, loading a vertex UV2 data set of the set basic hair model, loading a spatial position map Dmap, sampling pixel by pixel to obtain a vertex offset data set of the basic hair model, and finally obtaining a deformed hair model. The development efficiency of technicians is improved.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to an efficient and automatic hair-matching head shape generation method and a generation device thereof. Background technique [0002] With the development of big data face modeling, digital modeling of faces has become the norm. Through the relevant AI algorithm (artificial intelligence algorithm), a standard face shape can be changed into young, old, fat face, thin face, or even different genders. However, the change of the human face also needs to change the hairstyle corresponding to the 3D model. Since the hairstyle model has more faces than the face model, and the model is more random, the digital modeling of hairstyle is more difficult than the digital modeling of human face. In the case of a limited face library, the traditional method is to manually modify the hairstyle by 3D art modelers, so that the hairstyle can be adapted to various face shapes. But in the ...
