摘要
The present invention relates to a method for locating an object (1) integral with a triaxial magnetic sensor (2), evolving in a magnetic field generated by a set of at least three static triaxe magnetic generators (3) in a repository common, the method being characterized in that it comprises steps of: (a) For each generator (3) determination according to magnetic field measurements acquired by the sensor (2) and associated with said generator (3) of a position of said sensor (2) in said common reference frame; (b) calculating for each generator (3) a parameter representative of an error on said determined position of the sensor (2) for the generator (3); (c) selecting a subset of the set of generators (3) according to said estimated parameters for each of the generators (3); (d) estimating the position of the object (1) by merging the determined positions of the sensor (2) for each generator (3) selected in said subset.
