[0086] Example 1
[0087] According to the indoor positioning method provided by the embodiment of the present invention, the experiment is carried out in a room of 10 meters*10 meters, and a group of real magnetic field values is measured every 0.5 meters, and a total of 441 groups are measured, and then spatial interpolation is performed on the 441 groups of magnetic field values. The operation forms an 81*81 grid map. The results of selecting 20 positioning targets and walking 300 steps are compared with the root mean square error (RMSE).
