Abstract

The invention provides a driving method of a stylized object, a driving device of the stylized object, a computer readable medium and electronic equipment, and relates to the technical field of image processing. The method comprises the following steps: intercepting a neutral target object of which the target object is a neutral expression in a video containing the target object, and calculating a feature deformation parameter based on the neutral target object; reconstructing a stylized neutral target object based on the neutral preset object, the feature deformation parameter and the first deformation parameter; generating a stylized target expression base based on the neutral preset object, the feature deformation parameter and the second deformation parameter; and driving the stylized neutral target object based on the video and the stylized target expression base. According to the method, the step that a designer specially carries out expression base design when different stylized objects need to be driven can be avoided, and the design cost is reduced; meanwhile, driving of stylized objects of thousands of people and thousands of faces can be achieved, the driving effect is improved, and expansibility and transportability are enhanced.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to a method for driving a stylized object, a driving device for a stylized object, a computer-readable medium, and an electronic device. Background technique [0002] 3D modeling of human face is a very important technology, which is widely used in scenes such as movies, games, virtual reality, online social networking, face recognition and tracking. Expression-driven is an application direction of 3D face reconstruction. The 3D face model is established by designing parametric face model, fusion deformation expression base and face reconstruction. After completing the reconstruction of the 3D face model, it is usually necessary to calculate the label parameters and pose parameters of each frame of image to drive the face model in real time, so that the shape, expression and pose of the 3D face model are consistent with the input image. [0003] However, in t...
