Human body animation synthesis method based on human body soft tissue grid model

Abstract

The invention discloses a human body animation synthesis method based on a human body soft tissue grid model, and the method comprises the steps: firstly extracting the features of different dimensions of an image through a feature pyramid network, and then inputting the features of different dimensions into subsequent tasks such as human body part segmentation, soft tissue texture and posture estimation through a region-feature alignment technology.; and according to the three-dimensional posture and the soft tissue texture, mapping the figure in the original image to a three-dimensional human body soft tissue grid model to achieve reconstruction of the human body soft tissue grid model, and then achieved human body animation synthesis through redirection of the human body soft tissue grid model. By using the method of combining the human body soft tissue mesh model and the deep learning, the human body soft tissue motion can be accurately captured, so that the synthesized human bodyanimation details are richer in expression.

Description

technical field [0001] The invention relates to the field of algorithms for film and television production and virtual reality motion capture, and in particular to a method for synthesizing soft tissue motion human animation based on human body grid model redirection. Background technique [0002] The current motion capture system represented by the optical motion capture system relies on setting physical tracking points, relying on expensive and bloated external devices such as lasers and photosensitive sensors to determine the position of moving objects, and requires complicated post-processing work; and because setting physical tracking With a limited number of points, it is almost impossible for them to capture precise soft tissue motion. [0003] The current animation retargeting synthesis technology is limited to skeletal animation schemes. The skeleton is used to describe the action information, and the skin is used to represent the relationship between the human mesh...
