Embodiment Construction

[0068] The present invention will be further described below in conjunction with specific examples.

[0069] The method for reconstructing three-dimensional human body poses, expressions and gestures provided by this embodiment includes the following steps:

[0070] 1) Use a parametric model to represent the 3D human body mesh model to be reconstructed

[0071] Let the 3N composed of the vertex coordinates of the three-dimensional human body mesh model to be reconstructed V (where N V is the number of vertices of the 3D human mesh model to be reconstructed) the dimensional column vector is (where V is the vertex vector of the reconstructed mesh, v 1 is the coordinates of the first vertex, for the Nth V vertex coordinates, T is the transpose symbol), so it means that the three-dimensional human body mesh model to be reconstructed is to minimize the following energy:

[0072] ε(V,α,β)=ε S (V,α,β)+ε B (V,α,β)+ε G (V,α)+λε C (V,α,β)

[0073] Among them, α is the shape...

Abstract

The invention discloses a three-dimensional human body posture, expression and gesture reconstruction method. The method comprises the following steps: 1) representing a to-be-reconstructed three-dimensional human body grid model by using a parameterized model; 2) obtaining a three-dimensional human body grid model by minimizing energy, and 3) optimizing the energy in the step (2) by adopting an improved discrete shell deformation method. Shapes and posture parameters of the three-dimensional human body grid model with reconstruction can be solved from constraints of a given specific geometrical shape, so that the determined shape is approximate to given data.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional human body posture, expression and gesture reconstruction, in particular to a reconstruction method for three-dimensional human body posture, expression and gesture. Background technique [0002] There is already a large body of literature that studies parametric model representations for body pose, facial expression, and gesture, respectively. However, the problem of reconstructing the dynamic geometry of the complete human body is still an open problem. Due to the different scales of movement of different parts, the establishment of a complete parametric model of the human body has not attracted attention, and there are few related literatures. Most of the existing parametric representations are only for the body. , face, and hand movements. [0003] 3D deformable models. SCAPE combines pose motion data and skin weights to describe morphological and motion changes. The pose ...
