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

Method for generating a three-dimensional working surface of a human body comprising:

• receiving input data corresponding to geometric data;
• generating a first point cloud from the input data, each point being associated with a three-dimensional spatial coordinate;
• determining a plurality of attributes at each point of the first point cloud, said attributes comprising at least one shape descriptor, at least one shape descriptor being calculated from a sub-set of points in a vicinity of the considered point, at least one attribute of a point comprising data describing a normal vector at said point of the first point cloud,
• associating said attributes with each point to generate a second enriched point cloud;
• calculating a set of geometric parameters comprising at least one rotation at at least one point of the second enriched point cloud or at at least one articulation of a human body model and at least one shape coefficient by means of a regression, said regression being carried out from a series of matrix operations performed according to different layers of a neural network trained from a plurality of partial views of parametric models parameterised with different parameterisation configurations;
• determining a parameterised model to generate a body model of a body comprising a first meshing.
