Abstract: With the rapid development of smart home, researchers around the world have carried out numerous studies on its interactive interface. Based on virtual human technology, this paper explores the potential demand of virtual humans in smart home scenarios. Through the character design experience of designers, different facial features are grouped into limited anatomical dimensions as design rules. Under the guidance of these rules, cartoon stylized facial model templates can be made via comparing face image features to build a template library. Combined with face feature recognition as well as the mapping relationship between the face features and the cartoon model template-based aesthetic computing, automatic generation from two-dimnsional real face images to three-dimensional cartoon faces is realized. This generation method is lightweight, meets users’ personalized needs, and has been put into practical application.
