Abstract

The invention discloses a method for driving a virtual character and a device thereof. The method comprises the steps that a three-dimensional face model is constructed according to face information in an image; the expression and attitude control parameters of the three-dimensional face model are determined; and the expression and attitude control parameters are applied to a three-dimensional virtual character so that the expression and the attitude of the three-dimensional virtual character are maintained to be consistent with those of the face in the image. Therefore, the expression and the attitude of the face in the image can be tracked, and the virtual character is driven in a virtual space so that communication of the facial expressions between the character in the virtual space and other virtual characters is enabled to be highly personified; meanwhile, users can realize driving of the virtual character under the state of keeping easy and natural in the use process without operation of marking points on the face so as to have no user antipathy and enhance the user experience.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for driving a virtual character. Background technique [0002] Currently, functional modules capable of driving virtual characters appear in many smart terminal applications, especially game applications. During the user's use, this functional module can drive the virtual character according to the user's own behavior characteristics, give the user's own expression and other gestures to the virtual character, and present it to the user, as a character in the virtual space to communicate and interact with other characters , bringing great fun and rich experience to users. [0003] The smart terminal capable of driving virtual characters in the prior art is generally a special wearable camera device, and needs to fix the relative position of the user's face and the camera. Usually, in order to collect the user's face information more accurately, the user's f...
