Image processing method and apparatus, electronic device, and storage medium

An electronic device, comprising:

• a memory storing computer-readable instructions;
• and
• a processor, configured to execute the computer-readable instructions stored in the memory, to cause the electronic device to:
• obtain at least one reference surface model of a first skeleton posture of a virtual object, the at least one reference model located in a reference coordinate space;
• obtain one or more second skeleton postures of the virtual object;
• generate one or more exemplary surface models of the one or more second skeleton postures based on the at least one reference surface model and the one or more second skeleton postures;
• determine a posture transformation matrix between the first skeleton posture and the one or more second skeleton postures;
• convert the one or more exemplary surface models and the at least one reference surface model to the reference coordinate space using the posture transformation matrix to generate the virtual object according to the at least one reference surface model and the one or more exemplary surface models in the reference coordinate space, wherein in order to convert the one or more exemplary surface models and the at least one reference surface model to the reference coordinate space using the posture transformation matrix, the processor, upon execution of the computer-readable instructions, is configured to:
• perform a coordinate transformation on the one or more exemplary surface models using the posture transformation matrix to convert the one or more exemplary surface models to the reference coordinate space in which the at least one reference surface model is located;
• obtain a target skeleton posture of the virtual object;
• perform skin processing on the at least one reference surface model based on the target skeleton posture to obtain a target skeleton-skinning model of the target skeleton posture;
• determine a modified surface model of the target skeleton posture based on the at least one reference surface model and the one or more exemplary surface models in the reference coordinate space;
• and
• generate the virtual object based on the target skeleton-skinning model and the modified surface model.
