METHOD AND DEVICE FOR IDENTIFYING A SUBSET OF MEASUREMENTS, METHOD AND SYSTEM FOR LOCATING AN OBJECT, RECORDING MEDIUM FOR THESE METHODS

摘要

This method of identifying a subset of measurements comprising a measurement disturbed by a magnetic disturber, comprises: a) the emission of magnetic fields and the measurement (70) of these magnetic fields with the aid of N monoaxial source/monoaxial transducer pairs so as to obtain a set of N real measurements; b) the construction (72) of an estimation Pi of the position of an object on the basis of a subset Mi of the N measurements; c) the estimation (74) of N measurements on the basis of an estimated position Pi and of at least one direct model relating the position of the object to the set of N measurements, and d) the determination (76) of whether this subset Mi of measurements comprises a disturbed measurement or not by comparing the measurements estimated during step c) with the real measurements obtained during step a).
