Claim 13:
14. The system of claim 13, wherein the obtaining the candidate magnetic field information comprises:
obtaining information of the at least one pair of magnetic resonance peaks of the diamond NV center in the diamond NV center sensor, the information of the at least one pair of magnetic resonance peaks including at least one of a probe microwave frequency of each magnetic resonance peak, a fluorescence intensity of each magnetic resonance peak, or a linewidth of each magnetic resonance peak, wherein
the at least one pair of magnetic resonance peaks of the diamond NV center is obtained by splitting a total magnetic resonance peak of the diamond NV center via the reference magnetic field, and
each pair of the at least one pair of magnetic resonance peaks corresponds to the crystal axis direction of the diamond NV center; and

for each pair of the at least one pair of magnetic resonance peaks of the diamond NV center, determining the candidate magnetic field information related to the corresponding crystal axis direction of the diamond NV center based on the information of the pair of magnetic resonance peaks.
