  We develop a non invasive method for determine morphometric caracteristic of
individuals. We modelize a individual by a polyarticulated chain of rigid
segments and each of these segments corresponds to a volume. For this, each
segment is photographed under two orthogonal plans and each image is
digitalized. By assuming that the border of each segment can be described under
cylindric coordinates, the border is reconstructed by interpolation. Finally,
the principal morphometric data are determined.
