Abstract: The invention relates to a method for compensating a magnetic locator in the presence of a magnetic-field-disturbing material, comprising: an emitter (10) comprising at least one coil emitting an emission magnetic field; a receiver (20) comprising at least one receiving coil and a device providing a plurality of measurements Ipi of a receiving magnetic field induced by the emission field in each receiving coil; and a processing unit (25) comprising a field model allowing the calculation of a position (P) and/or an orientation (Q) of the receiver by means of calculation of a prediction Hi of the measurements according to a criterion (C) calculated according to an error Ei which is itself calculated in relation to the measurements Ipi.

Abstract: The invention relates to a method for calibrating a magnetic locator, said magnetic locator including at least a transmitter and a receiver, the calibration method involving a third sensor constituted of a transceiver, said method including, transmission of a first magnetic field by the transmitter and reception of first signals generated in the receiver by said magnetic field (S1), transmission of a second magnetic field by the transmitter and reception of second signals generated in the transceiver by said magnetic field (S2), transmission of a third magnetic field by the transceiver and reception of third signals generated in the receiver by said magnetic field (S3), the calibration method including the determination (S4) of at least a magnetic moment of the transmitter and a magnetic moment of the receiver from the first signals, second signals and third signals.
