no. 1 example

[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.

[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...

Abstract

The invention discloses a method and device for recognizing locating points. The method comprises the following steps: calculating a spacing distance between adjacent first and second locating points; calculating a motion distance of a located target according to motion step number of the located target between the first and second locating points; judging whether the spacing distance is larger than the motion distance; and recognizing the second locating point as an invalid locating point when the spacing distance is larger than the motion distance, wherein the locating time of the first locating point is ahead of that of the second locating point. According to the method, the rapid and accurate recognition of the invalid locating point is realized, the locating drift phenomenon is avoided, the locating accuracy is improved, and the user experience is improved. The calculation burden in the scheme is low, and the calculation is extremely simple, so that the processing speed is high, few resources are occupied, and the implementation cost is low.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method and device for identifying positioning points. Background technique [0002] With the improvement of people's living standards, more and more people keep pets. At the same time, keeping pets has become one of the ways for modern people to fill their lonely hearts. For example, office workers who have not had children regard pets as their own children. Therefore, A deep bond has been established between the pet and the owner. Once the pet is lost or stolen, it will not only cause material loss but also psychological harm to the owner. Therefore, a suitable positioning device is needed to monitor pets, so as to prevent pets from getting lost or stolen. [0003] Existing positioning devices are usually worn on the pet's neck as a pet collar, and the positioning device collects positioning data through a GPS (Global Positioning System, Global Positioning System)...
