A Method for 3D Human Reconstruction Animation

Abstract

The invention belongs to the technical field of three-dimensional dynamic graphics processing, and relates to a three-dimensional human body reconstruction animation method; the process steps include: S1, selecting a video segment of a single person, inputting it into a trained generation confrontation network model, and obtaining a three-dimensional rotation angle of human body joint points Sequence; S2, using the Savizkg‑Golag five-point quadratic smoothing algorithm to smooth the three-dimensional rotation angle of each joint point during the movement; S3, creating an initial three-dimensional cartoon model, combining the 23 joint points of the human body with the joints of the three-dimensional cartoon model The same joint points of the points are bound; S4, the obtained three-dimensional rotation angle is updated in the three-dimensional cartoon model, and the rendering effect of Unity3D is used to realize the synchronous change of the attitude of the three-dimensional cartoon model; Samples reduce the workload of sample preparation in the early stage; by introducing two-dimensional coordinates of joint points, three-dimensional coordinates, three-dimensional rotation angles, deviation values ​​​​of human body shape parameters, and resistance loss values, the model accuracy is greatly improved.
