Embodiment Construction
[0054] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.
[0055] refer to Figure 1 to Figure 3 , a four-point magnetic field positioning method based on a rotating magnetic dipole, comprising: S101. Constructing a magnetic source coordinate system and an observation coordinate system, and a magnetic field model of the rotating magnetic dipole; S102. According to the magnetic source coordinate system and the magnetic field The model determines the relationship between the coordinates of the observation point on the magnetic source coordinate system and the magnetic field distribution of the rotating magnetic dipole; S103. According to the equivalent relationship between the rotating magnetic dipole on the observation coordinate system and the magnetic source coordinate system, and Its magnetic...
