Abstract:
1. A method for three-dimensional (3D) reconstruction of an object in a scene exposed to a wave, based on signals back-scattered by the scene and sensed, the method comprises: generating, from the sensed signals, a set of 3D points to which their back-scattering intensity by the scene is respectively assigned, the 3D points associated with their intensity being denoted set A of reconstructed data, starting from the set A of reconstructed data, extracting a set B of data, whose points are located within a volume containing the object, as a function of volume characteristics F starting from the set B, extracting a set C of data characterizing an external surface of the object, the external surface having regions with missing parts, depending on an extraction criterion F filling in the regions, based on the data of C, with missing parts by generating a three-dimensional surface so as to obtain a set D of completed data of the object, without having to use an external database, the filling step comprising the following sub-steps: identifying the object based on the three-dimensional surface D.
