Abstract

The present disclosure relates to a method for estimating the position of a magnet using a tracking device comprising an array of magnetometers, the method comprising phases of determining an initial state vector associated with the magnet, of measuring a useful magnetic field, of estimating a magnetic field, of calculating a bias between the measured magnetic field and the estimated magnetic field, and of updating the state vector on the basis of the bias. It also comprises an identifying phase comprising a step of identifying a magnetic disturbance on the basis of an indicator calculated depending on an estimated magnetic field and a measured magnetic field.

Abstract

The invention is a method for tracking a position of a magnet moving relative to a magnetometer array. On the basis of the magnetic field detected by each magnetometer of the array, the position of the magnet is estimated. This estimation is based on taking into account a reference magnetic field established beforehand, this reference magnetic field being subtracted from the magnetic field detected by each magnetometer, so as to form a differential measurement. The various successive estimations of the position of the magnet allow its path to be tracked.

Abstract

A method for locating at least one movable magnetic object with respect to an array of at least N triaxial magnetometers comprises steps consisting in: subtracting a weighted average from each of the measurements to obtain modified measurement; loading the modified measurements and a location of the one or more movable magnetic objects at the current time as input into a filtering operation for locating the one or more movable magnetic objects; implementing the location filtering operation, this comprises steps consisting in: subtracting a weighted average from each of the estimated data; and delivering as output a location of the one or more movable magnetic objects at a subsequent time.
