Device and method for modeling 3D (three-dimensional) hair based on 3D hair template

The invention provides a device and method for modeling 3D (three-dimensional) hair based on a 3D hair template. The device comprises a 3D hair template library and a 3D hair model generation unit, wherein the 3D hair template library is used for storing one or more 3D hair templates in advance; the 3D hair model generation unit is used for receiving a front elevation hair image and a 3D head model; and a real 3D hair model is generated by processing one or more 3D hair templates provided by the 3D hair template library based on the characteristics of the front elevation hair image in combination with the 3D head model.
