1. Volume recognition method comprising the steps of:

  • a) capturing three-dimensional image data using a 3D imaging system (3), wherein said image data represent a plurality of points (5), each point (5) having at least a set of coordinates in a three-dimensional space;

    b) grouping at least some of the points (5) in a set of clusters (6); and

    c) selecting, according to a first set of parameters such as position and size, a cluster (6) corresponding to an object of interest (1) located in range of said imaging system (3);

    and characterised in that it further comprises the steps of;

    d) grouping at least some of the points (5) of the selected cluster (6) in a set of sub-clusters according to a second set of parameters comprising their positions in the three-dimensional space, wherein each sub-cluster has a centroid (11) in the three-dimensional space; and

    e) associating a volume (12) to each of at least some of said sub-clusters, wherein said volume (12) is fixed to the centroid (11) of said sub-cluster.
