METHOD FOR DETERMINING THE POSITION OF AN EXCITATION ON A SURFACE AND DEVICE FOR IMPLEMENTING SUCH A METHOD

摘要

A method for determining the position of the origin of an excitation on a surface of an object (3) fitted with transducers (4) comprising the steps of : (a) receiving signals Si(t) originating from said transducers; (b) calculating a signature SIGs of these signals; (c) comparing this signature SIGs with predetermined reference signatures SIGrRj, by a calculus of a resemblance function RESj; (d) determining a reference point j0 nearest to the origin of the excitation, based on the resemblance function and on a computation of a validation criterion.
