Abstract

The embodiment of the invention provides a three-dimensional exaggerated cartoon face generation method and device. The method comprises the following steps: inputting a normal face picture into a 3D-CariGAN model, outputting a PCA coefficient of a three-dimensional exaggerated cartoon face, and recovering the geometric model of the three-dimensional exaggerated cartoon face according to the PCA coefficient based on the PCA model of the three-dimensional exaggerated cartoon face; reconstructing a three-dimensional normal face according to the normal face picture, projecting the three-dimensional normal face to the normal face picture, and obtaining texture mapping of the three-dimensional exaggerated cartoon face; inputting the normal face picture into the CariStyGAN, and outputting the texture map of the three-dimensional exaggerated cartoon face; and obtaining the three-dimensional exaggerated cartoon face according to the geometric model, the texture mapping and the texture mapping.According to the embodiment of the invention, the natural complete three-dimensional exaggerated cartoon face is automatically generated by utilizing the PCA model of the three-dimensional exaggerated cartoon face.

Description

technical field

[0001] The invention belongs to the technical field of three-dimensional face reconstruction, and in particular relates to a method and a device for generating a three-dimensional exaggerated cartoon face. Background technique

[0002] Exaggerated caricature faces are an expressive art form, often used for propaganda or to criticize the current situation. Three-dimensional exaggerated caricature faces are three-dimensional exaggerated caricature faces, which are more vivid than two-dimensional exaggerated caricature faces, and are widely used in the field of animation.

[0003] It takes a lot of time and energy for an artist to design a three-dimensional exaggerated caricature face, but it is difficult for ordinary people to design a three-dimensional exaggerated caricature face without sufficient professional skills. Therefore, the automatic generation of three-dimensional exaggerated caricature faces brings great convenience. Existing methods for automati...
