Method for generating a three-dimensional working surface of a human body, system

A method for generating a three-dimensional working surface of a human body, the method comprising:

• receiving input data corresponding to geometric data;
• generating a first point cloud of points from the input data, each point being associated with a three-dimensional spatial coordinate;
• generating partial views of parameterised body models corresponding to a parametric body model parameterised with different parameterisation configurations, each one of the parameterised body models being represented by a point cloud so that the parameterised body models are represented by point clouds;
• wherein the parametric body model models the human body in which a set of articulations are predefined, each parameterisation configuration of the different parameterisation configurations being defined by a set of modelling parameters comprising at least one first angle of rotation of each articulation of the set of articulations and at least one first shape coefficient;
• calculating a set of geometric parameters comprising at least one rotation at at least one point of the first point cloud or at at least one articulation of a human body model and at least one shape coefficient by a regression, said regression being carried out from the first point cloud and from a series of matrix operations performed according to different layers of a neural network trained from the partial views, wherein entry parameters of the neural network comprise three dimensional spatial coordinates, and
• determining another parameterised model from the set of geometric parameters to generate a body model of the human body comprising a first meshing,
• wherein each partial view of the plurality of partial views is generated from a subset of points of one of the point clouds.
