Abstract
The system (7) for plotting the shape of a tri-dimensional object (2) is used in particular for the profile of a plantar arch (20). It comprises a sensing device (1) having rods (3) movable in a support (10, 11) such that said object (2) can be applied onto the first end (300) of each of said rods under a determined pressure force so as to drive said rods (3) in a translation motion and such that the set of the second ends (301) of said rods (3) define a surface (S.sub.A) replicating said shape to be plotted (20). Spring means (4) are associated with said movable rods (3) to oppose a calibrated resilient force opposing said pressure force. The system further comprises a contactless acquisition device (5) for acquiring and digitalizing said surface (S.sub.A) replicating said shape to be plotted (20), said device (5) delivering output electric signals (V.sub.S) correlated with the space coordinates of said second end (301) of said rods (3), with respect to reference coordinates (P.sub.R) defined by the position taken by the rods in a so-called rest state.
