The invention relates to a method of localisation of vector magnetometers arranged in a network, comprising the following steps:n generation (EMi), by a magnetic field source (S), of m reference magnetic fields with known amplitudes and known and distinct directions; measurement (MESj) of the m reference magnetic fields along n axes of magnetometers in the network, m and n being such that m*n≥6; determination (LOCj) of the position and orientation of magnetometers of the network from said measurements, relative to the magnetic field source. nn The invention also includes a magnetic field measurement instrument that includes a network of vector magnetometers and is capable of implementing the localisation method. n Application to the imagery of biomagnetic fields, for example in magnetocardiography or in magnetoencephalography. |
