A method for generating a model of a flat object from views taken by at least two calibrated cameras, which is capable of generating two-dimensional and volumetric representations of the object, where the representations can be a depth map, a volumetric representation or a mesh representation, method including the following basic steps: calibrating at least two cameras, calculating several 3D coordinates of at least three points belonging to the same plane of the flat object, calculating the equation of the plane of the flat object, selecting at least one region representing the surface of the flat object, in at least one view provided by at least one camera, and calculating the intersection between the selected region representing the surface of the object and the equation of the plane.
