Embodiment 1

[0044] Embodiment 1 of the present invention provides an indoor positioning method. Please refer to figure 1 , the indoor positioning method includes:

[0045] S10. The transmitter 10 sends a two-point positioning request and the location information of the transmitter to the receiver 20.

[0046] The location information of the transmitter can be based on a specific indoor positioning system, or based on GPS (Global Positioning System). Outdoor positioning can also be realized based on GPS.

[0047] It is preferable to use millimeter wave communication between the transmitting end 10 and the receiving end 20. The millimeter wave has the characteristics of high gain, high tracking accuracy and high guidance accuracy, which can effectively improve the positioning accuracy of indoor positioning. That is, in this embodiment, a millimeter wave array antenna is provided on both the transmitting end 10 and the receiving end 20 .

[0048] S20. After receiving the two-point positio...

Embodiment 2

[0066] This embodiment provides an indoor positioning system, which is used to implement the indoor positioning method described in Embodiment 1.

[0067] Please refer to figure 2 , the indoor positioning system includes a transmitter 10 and a receiver 20 .

[0068] The transmitter 10 is used to send the two-point positioning request and the location information of the transmitter to the receiver 20 .

[0069] The receiving end 20 is used to send the two-point positioning request feedback to the transmitting end 10 after receiving the two-point positioning request and the position information of the transmitting end, and adjust the radiation direction of the antenna of the receiving end 20 toward the transmitting end 10 .

[0070] The transmitting end 10 is further configured to obtain the distance between the transmitting end 10 and the receiving end 20 based on the sending time of the two-point positioning request and the receiving time of the two-point positioning request...

Embodiment 3

[0080] The third embodiment provides a storage medium, the storage medium stores a plurality of instructions, and the instructions are suitable for being loaded by a processor to execute the steps in the indoor positioning method described in the first embodiment.

[0081] The computer storage medium described in the embodiments of the present invention may use any combination of one or more computer-readable media. The computer readable medium may be a computer readable signal medium or a computer readable storage medium. A computer readable storage medium may be, for example, but not limited to, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination thereof. More specific examples (non-exhaustive list) of computer readable storage media include: electrical connections with one or more leads, portable computer disks, hard disks, random access memory (RAM), read only memory (ROM), Erasable programmable re...

Abstract

The invention discloses an indoor positioning method and system and a storage medium. The method comprises the steps that a transmitting end sends a two-point positioning request and transmitting endposition information to a receiving end; after receiving the two-point positioning request and the position information of the transmitting end, the receiving end transmits two-point positioning request feedback to the transmitting end and adjusts the antenna radiation direction of the receiving end towards the transmitting end; after the transmitting end receives the feedback of the two-point positioning request, the distance between the transmitting end and the receiving end is obtained based on sending time of the two-point positioning request and receiving time fed back by the two-point positioning request; the transmitting end adjusts the antenna radiation direction of the transmitting end until the signal between the transmitting end and the receiving end is the strongest, and the antenna radiation direction at the moment is recorded as the strongest radiation direction of the transmitting end; and the transmitting end obtains the relative position of the transmitting end and thereceiving end based on the distance between the transmitting end and the receiving end and the strongest radiation direction of the transmitting end, and two-point positioning is completed. The method can be applied to indoor vehicle or parking space searching and other scenes, and has a wide application prospect.

Description

technical field [0001] The present invention relates to the communication field, in particular to an indoor positioning method, system and storage medium. Background technique [0002] At present, GPS positioning technology has been widely used, but due to indoor signal blockage, GPS positioning technology cannot be directly applied indoors, causing indoor positioning technology to become a major problem in the industry. Indoor positioning technology is widely used. For example, in a basement parking lot, the indoor positioning technology can be used to locate the vehicle position so that users can quickly find their own vehicles. Therefore, it is urgent to find an effective indoor positioning method to achieve indoor high-precision positioning. Contents of the invention [0003] The object of the present invention is to provide an indoor positioning method, system and storage medium to solve the above problems. [0004] For reaching this purpose, the present invention a...
