Virtual face modeling method based on real face image

Abstract

The invention discloses a virtual face modeling method based on a real face image. The method comprises the following steps: 1) manufacturing a head model; 2) making a facial expression action chartlet set; 3) in the Unity 3D, using a frame animation machine built in the Unity 3D to make various obtained expression action chartlet sets into corresponding expression animations; 4) manufacturing anexpression animation controller; 5) decorating the hair accessory on the 3D head model to modify the face; 6) writing a script to control the displacement of the 3D head model except the face, so thatthe 3D head model does corresponding movement along with the face displacement. According to the method, the face of the established 3D virtual head model is modified by adopting the facial expression image of the real person, so that the recognition degree of the face of the established virtual character head model and the face of the real person is extremely high; and the modeling process doesnot need to carry out complex space design like existing 3D software modeling, the modeling time is shorter, and the cost is lower.

Description

technical field [0001] The invention relates to the technical field of three-dimensional modeling, in particular to a virtual face modeling method based on real face images. Background technique [0002] With the continuous development of science and technology, people have a higher pursuit of quality of life, and the emergence of communication robots makes people's eyes shine. The rise of VR technology makes it more experiential and technological. After wearing VR equipment, the experiencer can interact with virtual robots in a computer-generated simulation environment. The future market of virtual robots has begun to infiltrate into the host industry and welcome industry. It is expected that in the near future, virtual robots will be widely used in various service industries. [0003] Unity 3D is the most widely used platform to support virtual interaction. In order to make the interaction more realistic, the humanoid performance of the character model imported into Unity...
