Summary:The invention provides a noise elimination magnetic field measurement method and a magnetic field measurement system, and the method comprises the steps: respectively collecting the magnetic field data of a measurement point and each reference point in a same background field, a fitting regression relation between the magnetic field data of the measurement points and the magnetic field data of the reference points after dimension reduction and a calibration coefficient are obtained based on a fitting regression algorithm; and collecting the magnetic field data of the measurement points and the reference points in the same superimposed field again, and substituting the calibration coefficient into the fitting regression relationship between the magnetic field data of the measurement points and the magnetic field data of the reference points after dimension reduction again to obtain a real magnetic field signal of the to-be-measured magnetic field. According to the method, the magnetic field noise features can
