Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to a three-dimensional image processing method and device, a virtual image generation method, and electronic equipment. Background technique [0002] In recent years, facial expression deformation transfer technology has been widely used in the fields of computer animation, computer games and computer vision. However, the deformation model of the target object obtained according to the existing deformation transfer technology and the target object model are usually not aligned (or scattered in various places in space), resulting in inconsistencies in the animation construction using the deformation model of the target object obtained according to the related deformation transfer technology. When creating a virtual character image, it is necessary to manually align the deformation models of each target object, and then synthesize a three-dimensional character i...

However, the deformation model of the target object obtained according to the existing deformation transfer technology and the target object model are usually not aligned (or scattered in various places in space), resulting in inconsistencies in the animation construction using the deformation model of the target object obtained according to the related deformation transfer technology. In the virtual character image, it is necessary to manually align the deformation models of each target object, and then synthesize the three-dimensional character image according to the aligned target object deformation model

This method consumes a lot of manpower and material resources, and the production efficiency is low.
