[0067] refer to figure 1 , propose the first embodiment of the method for identifying anchor points of the present invention, the method includes the following steps:
[0068] S12. Calculate the distance between the adjacent first positioning point and the second positioning point, where the first positioning point is an effective positioning point whose positioning time is earlier than that of the second positioning point.
[0069] In the embodiment of the present invention, the obtained first positioning point and the second positioning point are two adjacent positioning points, and the first positioning point is an effective positioning point whose positioning time is earlier than that of the second positioning point. For example, the server defines the positioning point obtained this time as the second positioning point, and defines the valid positioning point obtained in the previous time as the first positioning point.
[0070] The positioning point is the position wher...

[0090] see Figure 4 , propose a fourth embodiment of the method for identifying anchor points in the present invention, the method includes the following steps:
[0091] S21. Calculate the distance between the adjacent first positioning point and the second positioning point, where the first positioning point is an effective positioning point whose positioning time is earlier than that of the second positioning point.
[0092] This step S21 is the same as the step S12 in the first embodiment, and will not be repeated here.
[0093] S22. Calculate the movement speed according to the separation distance and the positioning interval time of the two positioning points.
[0094] In this embodiment, steps S22 and S23 are added on the basis of the first embodiment.
[0095] In this step S22, the server subtracts the positioning time of the first positioning point from the positioning time of the second positioning point, and uses the calculated difference as the positioning interval...
