PROBLEM TO BE SOLVED: To provide a method of detecting mobile magnetic objects present before a network of magnetometers.SOLUTION: A method of detecting mobile magnetic objects comprises: identifying (168; 211), on the basis of the mobile objects present before a network of magnetometers, a supplementary equation connecting, by means of a relationship of equality, a first variable from a current system of equations to a term, the term being a predefined relationship between one or more other variables from the current system of equations or a constant value; replacing (180; 216), in the current system of equations, the first variable with the term to which the first variable is equal, to obtain a new system of equations in which the number of variables for which the value needs to be estimated is smaller than in the current system of equations; and using the new system of equations instead of the current system of equations in order to estimate the position, orientation and amplitude of magnetic moments of the magnetic objects. |
