[0003] The present application relates to the field of communication technology, and in particular, to a head-mounted device and a positioning method. BACKGROUND

[0004] With the increasing use of head-mounted devices, the functions of such devices are becoming increasingly powerful. For example, a head-mounted device can provide a positioning service for a user. However, how to improve the positioning accuracy of a head-mounted device is a technical problem to be solved at present. SUMMARY

[0005] Embodiments of the present application provide a head-mounted device and a positioning method for improving positioning accuracy.

[0006] In a first aspect, a head-mounted device is provided, which includes a first antenna branch and a second antenna branch, the first antenna branch and the second antenna branch being configured to receive a positioning signal, the positioning signal being used for positioning the head-mounted device; wherein the first antenna branch and the second antenna branch are connected, and the first antenna branch and the second antenna branch are horizontally arranged on the head-mounted device and vertically arranged.

[0007] In the embodiments of the present application, the first antenna branch and the second antenna branch are horizontally arranged, which can make the electromagnetic waves radiated by the first antenna branch and the second antenna branch perpendicular to the ground, thereby helping to improve the signal-to-noise ratio of the signals received by the first antenna branch and the second antenna branch, and thus improving the positioning accuracy. In addition, the first antenna branch and the second antenna branch are vertically arranged, which can form a perpendicular radiation electric field, realize orthogonal polarization of the radiation electric fields of the first antenna branch and the second antenna branch, and thus make the first antenna branch and the second antenna branch radiate electromagnetic waves with right-handed circular polarization characteristics, which are the same as the polarization characteristics of the electromagnetic waves used to carry the positioning signal, thereby helping to further improve the signal-to-noise ratio of the signals received by the first antenna branch and the second antenna branch, and thus improving the positioning accuracy.

[0008] In a possible implementation, the head-mounted device is glasses, the glasses include a frame, a leg and a lens, the first antenna branch is arranged on the leg, the second antenna branch is arranged on the frame, or the second antenna branch is arranged on the lens.

[0009] In the technical solution, the antenna branch is arranged on the frame (or the lens), which can increase the radiation aperture (for example, the total length of the antenna branch) of the antenna, and help to improve the radiation strength of the antenna. In addition, the frame (or the lens) is relatively far from the head of a person, so that the antenna branch arranged on the frame (or the lens) can reduce the absorption of the radiation energy of the antenna by the human body, and improve the radiation efficiency of the antenna.

[0010] In a possible implementation, the current directions of the first antenna branch and the second antenna branch are the same.

[0011] When the current directions of the first antenna branch and the second antenna branch are the same, an orthogonal radiation electric field can be formed, the first antenna branch and the second antenna branch can be orthogonally polarized, so that the polarization characteristics of the electromagnetic wave radiated by the first antenna branch and the second antenna branch are close to the polarization characteristics of the electromagnetic wave used to carry the positioning signal, the first antenna branch and the second antenna branch can better receive the positioning signal, and the positioning accuracy can be improved.

[0012] In a possible implementation, the head-mounted device further includes a first circuit board, the first circuit board is connected with the first antenna branch and the second antenna branch, and the current direction of the first circuit board is opposite to the current directions of the first antenna branch and the second antenna branch.

[0013] In the technical solution, the current directions of the first circuit board, the first antenna branch and the second antenna branch are opposite, so that the first circuit board can reflect the energy radiated downward by the first antenna branch and the second antenna branch to the upper side, thereby improving the upward radiation energy of the antenna, and improving the signal-to-noise ratio of the signal received by the first antenna branch and the second antenna branch, and improving the positioning accuracy.

[0014] In a possible implementation, the head-mounted device further includes a display module and / or a microphone, the display module is used to display positioning information, and the microphone is used to play the positioning information, wherein the positioning information is determined according to the positioning signal.

[0015] In the technical solution, the positioning information can be displayed by the display module or played by the microphone, so that the user can know the current position information in time, and the user experience can be improved.

[0016] In a possible implementation, the first antenna branch and / or the second antenna branch are further configured to send positioning information to the first device, the positioning information being determined according to the positioning signal. Multiplexing the antenna branch used to receive the positioning signal to send the positioning information to other devices, without having to additionally set up an antenna to send the positioning information to other devices, can reduce the space occupied by the antenna in the head-mounted device, and help reduce the volume and complexity of the head-mounted device. In addition, the first device can perform positioning based on the positioning information sent by the head-mounted device, and the positioning accuracy is higher.

[0017] In a possible implementation, the head-mounted device further includes a third antenna branch, and the third antenna branch is configured to send positioning information to the first device, the positioning information being determined according to the positioning signal.

[0018] In the technical solution described above, the third antenna branch is used to send the positioning information to other devices, so that the first antenna branch and the second antenna branch do not have to be switched to the sending state, but can remain in the receiving state to receive the positioning signal. Therefore, the receiving and sending states of the first antenna branch and the second antenna branch do not have to be frequently switched, which can reduce the power consumption caused by switching the states of the antennas, and simplify the operation of the head-mounted device. In addition, the probability of missing the positioning signal can be reduced, and the positioning accuracy can be improved.

[0019] In a second aspect, a positioning method is provided, which can be implemented by the head-mounted device of the first aspect, and the method includes: receiving a positioning signal, and the polarization characteristic of the electromagnetic wave used to carry the positioning signal is the same as the polarization characteristic of the electromagnetic wave radiated by the first antenna branch and the second antenna branch.

[0020] In the embodiments of the present application, the first antenna branch and the second antenna branch are perpendicular, so that the polarization characteristic formed by the first antenna branch and the second antenna branch is the same as the polarization characteristic of the electromagnetic wave of the positioning signal, which enables the head-mounted device to better receive the positioning signal, and thus helps improve the positioning accuracy.

[0021] In a possible implementation, the method further includes: determining positioning information based on the positioning signal.

[0022] In a possible implementation, the method further includes one or more of the following: sending the positioning information to the first device; displaying the positioning information; or playing the positioning information.

[0023] For the technical effects brought by the second aspect or various optional implementations, reference can be made to the introduction of the technical effects of the first aspect or the corresponding implementation.

[0024] In a third aspect, a computer readable storage medium is provided, which stores a computer program, and when the computer program is run on a computer, the computer is enabled to perform the method provided in the second aspect.

[0025] In a fourth aspect, a computer program product is provided, which comprises a computer program, and when the computer program is run on a computer, the computer is enabled to perform the method provided in the second aspect. BRIEF DESCRIPTION OF DRAWINGS

As used in the specification and the appended claims, the singular forms “a,” “an” and “the” are intended to include both singular and plural forms, unless the context clearly indicates otherwise.

[0034] In this specification, the reference to “one embodiment” or “some embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application.

[0035] A head-mounted device is an electronic device worn on the head of a user, and the head-mounted device can include head-mounted devices such as glasses and a smart helmet. Among them, the glasses can include virtual reality (VR) glasses, augmented reality (AR) glasses, smart glasses, and the like.

[0036] The head-mounted device can provide a positioning service for the user, for example, the head-mounted device can receive a positioning signal from a satellite through an antenna, and determine the positioning information of the user according to the positioning signal. However, if the user is in an environment where the positioning signal is weak, such as a forest, a high-rise community, and the like, it can cause the head-mounted device to receive the positioning signal with poor effect, thereby causing low positioning accuracy.

[0037] In view of this, the embodiment of the present application provides a head-mounted device for improving positioning accuracy. Please refer to FIG. 1, which is a structural block diagram of a head-mounted device provided by the embodiment of the present application, and FIG. 1 takes the head-mounted device as an example of smart glasses. The head-mounted device includes a first antenna branch 10 and a second antenna branch 11, and the first antenna branch 10 and the second antenna branch 11 are used to receive a positioning signal for positioning the head-mounted device.

[0038] Among them, the first antenna branch 10 and the second antenna branch 11 are connected, the first antenna branch 10 and the second antenna branch 11 are horizontally arranged on the head-mounted device, and the first antenna branch 10 and the second antenna branch 11 are perpendicular. Among them, the horizontal arrangement of the first antenna branch 10 and the second antenna branch 11 can make the electromagnetic waves radiated by the first antenna branch 10 and the second antenna branch 11 perpendicular to the ground, which helps to improve the signal-to-noise ratio of the signals received by the first antenna branch 10 and the second antenna branch 11, thereby improving the positioning accuracy. Moreover, the vertical arrangement of the first antenna branch 10 and the second antenna branch 11 can form an orthogonal radiation electric field, realize the orthogonal polarization of the radiation electric fields of the first antenna branch 10 and the second antenna branch 11, so that the first antenna branch 10 and the second antenna branch 11 can radiate electromagnetic waves with right-handed circular polarization characteristics, which are the same as the polarization characteristics of the electromagnetic waves used to carry the positioning signal, which helps to further improve the signal-to-noise ratio of the signals received by the first antenna branch 10 and the second antenna branch 11, and helps to improve the positioning accuracy. It can be understood that the connection mode of the first antenna branch 10 and the second antenna branch 11 in FIG. 1 is only an example, and the first antenna branch 10 and the second antenna branch 11 can also be other connection modes, for example, the first antenna branch 10 and the second antenna branch 11 are perpendicular to each other, and the embodiment of the present application does not limit the connection mode of the first antenna branch 10 and the second antenna branch 11.

[0039] Optionally, the first antenna branch 10 and the second antenna branch 20 can be in the same horizontal plane, or the first antenna branch 10 and the second antenna branch 11 can also be in different horizontal planes, and the embodiments of the present application do not limit this. In FIG. 1, the first antenna branch 10 and the second antenna branch 11 are taken as an example in the same horizontal plane.

[0040] As described above, the head-mounted device can be, for example, glasses (for example, smart glasses), or can also be a smart helmet. If the head-mounted device is smart glasses, the first antenna branch 10 can be horizontally arranged on the temple of the smart glasses; the second antenna branch 11 can be arranged on the frame or lens, for example, the second antenna branch 11 can be horizontally arranged on the upper and lower frames, or can also be horizontally arranged at any position of the lens. Optionally, the extension direction of the first antenna branch 10 is the same as the extension direction of the temple. If the head-mounted device is a smart helmet, the first antenna branch 10 and the second antenna branch 11 can be arranged in a manner similar to the arrangement of the first antenna branch 10 and the second antenna branch 11 in smart glasses, which will not be described here; or the first antenna branch 10 and the second antenna branch 11 can be arranged at the top of the smart helmet, or can also be arranged at other positions convenient for receiving signals from above the head, and the embodiments of the present application do not limit this. In the following embodiments, the head-mounted device is taken as an example of smart glasses.

[0041] Optionally, when the first antenna branch 10 is arranged on the temple and the second antenna branch 11 is arranged on the frame, in order to reduce the influence of the shell of the temple or the frame on the positioning signal reception, the first antenna branch 10 can be arranged on the upper edge of the temple, and the second antenna branch 11 can be arranged on the upper edge of the frame.

[0042] For the antenna branch arranged on the shell of the smart glasses, the antenna branch can be realized by, for example, a laser direct structuring (LDS) process, or can also be realized by a traditional printed circuit board (PCB) or flexible printed circuit (FPC) process; for the antenna branch arranged on the lens, considering the light transmittance of the lens, the antenna branch can be realized by a transparent metal process, for example, can be realized by indium tin oxide (ITO) or metal mesh.

[0043] Please refer to Fig. 2, an intelligent glasses provided by the embodiment of the application, the intelligent glasses comprising a first antenna branch 10, a second antenna branch 11, a glasses leg 20, a glasses leg 21, a glasses frame 22, a glasses frame 23, a glasses lens 24 and a glasses lens 25. Wherein, the glasses lens 24 is fixed in the glasses frame 22, the glasses lens 25 is fixed in the glasses frame 23, one end of the glasses leg 20 is connected with the glasses frame 22, one end of the glasses leg 21 is connected with the glasses frame 23.

[0044] In Fig. 2, the first antenna branch 10 is horizontally arranged on the upper edge of the glasses leg 20, and the second antenna branch 11 is horizontally arranged on the upper edge of the glasses frame 22. In actual application, the second antenna branch 11 can also be arranged at other positions, for example, the second antenna branch 11 can also be horizontally arranged on the upper edge of the glasses frame 23, or can also be horizontally arranged at any position of the glasses lens 24 or the glasses lens 25, and the embodiment of the application does not limit this.

[0045] Wherein, if the second antenna branch 11 is horizontally arranged on the upper edge of the glasses frame 22, the first antenna branch 10 and the second antenna branch 11 can be directly connected; if the second antenna branch 11 is horizontally arranged on the upper edge of the glasses frame 23, and no antenna branch is arranged on the glasses frame 22, the first antenna branch 10 and the second antenna branch 11 cannot be directly connected, and the first antenna branch 10 and the second antenna branch 11 can be connected by other ways, for example, can be connected by a wire, etc.

[0046] Optionally, the current directions of the first antenna branch 10 and the second antenna branch 11 are the same, and the first antenna branch 10 and the second antenna branch 11 can form a quadrature radiation electric field when energized, realizing orthogonal polarization of the radiation electric field of the first antenna branch 10 and the second antenna branch 11, so that the polarization characteristics of the electromagnetic wave radiated by the first antenna branch 10 and the second antenna branch 11 are close to the polarization characteristics of the electromagnetic wave used to carry the positioning signal, and the first antenna branch 10 and the second antenna branch 11 can better receive the positioning signal, which helps to improve the positioning accuracy.

[0047] Optionally, the head-mounted device further comprises a first circuit board 30, the first circuit board 30 is connected with the first antenna branch 10 and the second antenna branch 11, and the current direction of the first circuit board 30 is opposite to the current directions of the first antenna branch 10 and the second antenna branch 11. Wherein, the connection point of the first circuit board 30 with the first antenna branch 10 or the second antenna branch 11 can be an antenna feed point, for example.

[0048] Optionally, the first circuit board 30 is arranged below the first antenna branch 10 or the second antenna branch 11, and the first circuit board is parallel to the first antenna branch 10 or the second antenna branch 11.

[0049] With the first circuit board 30 arranged in the temple 20 as an example, please refer to FIG. 3, which is a partial enlarged view of the temple 20 shown in FIG. 2. As shown in FIG. 3, the temple 20 can include a housing 201, the first antenna branch 10 and the first circuit board 30, wherein the first antenna branch 10 is arranged at the upper edge of the housing 201, the housing 201 has a receiving cavity (not shown in the figure), the first circuit board 30 can be arranged in the receiving cavity, and the first circuit board 30 is parallel to the first antenna branch 10. In this way, since the current directions of the first circuit board 30 and the first antenna branch 10 are opposite, the first circuit board 30 can reflect the electromagnetic waves radiated downward by the first antenna branch 10 to the upper side, thereby helping to improve the energy of the electromagnetic waves radiated upward by the first antenna branch 10, and the first antenna branch can better receive signals.

[0050] Optionally, the temple 20 can further include a battery 40, which can be arranged in the receiving cavity for power supply, for example, power supply for the first circuit board 30, the first antenna branch 10 and the second antenna branch 11.

[0051] The first circuit board 30 can process the positioning signals received by the first antenna branch 10 and the second antenna branch 11 to obtain positioning information. For example, please refer to FIG. 4, which is a structural schematic diagram of the first circuit board 30 provided in the embodiments of the present application. As shown in FIG. 4, the first circuit board 30 includes a radio frequency front-end part and a system on chip (SOC) part. Wherein, the radio frequency front-end part includes a combiner 301, a low noise amplifier (LNA) 302, a filter 303 and a filter 308, and the SOC part includes a positioning signal processing chip 305 and a master control chip 306. Optionally, the positioning signal processing chip 305 and the master control chip 306 can be independently arranged, or can also be integrated in the same chip, and the embodiments of the present application do not limit the arrangement form of the positioning signal processing chip 305 and the master control chip 306.

[0052] The combiner 301 is connected with the first antenna branch 10 and the second antenna branch 11, for processing the positioning signals received by the first antenna branch 10 and the second antenna branch 11, and inputting the processed signals into the low noise amplifier 302. Wherein, the positioning signals are, for example, signals from the global navigation satellite system (GNSS). Optionally, the positioning signals can include high frequency band (for example, L5) signals and low frequency band (for example, L1) signals, and the combiner 301 can be a combination of high pass filters and low pass filters, for separating the positioning signals (i.e. L1 signals and L5 signals) from other signals, and inputting the obtained positioning signals into the low noise amplifier 302.

[0053] The low noise amplifier 302 is configured to amplify the positioning signal input by the combiner 301, and input the amplified positioning signal to the filter 303.

[0054] The filter 303 is configured to separate the L1 signal and the L5 signal in the positioning signal, to obtain the L1 signal and the L5 signal, and input the L1 signal and the L5 signal to the positioning signal processing chip 305.

[0055] The positioning signal processing chip 305 is configured to determine the positioning information according to the L1 signal and the L5 signal. For example, the positioning signal processing chip 305 can perform frequency down-conversion, demodulation and decoding processing on the L1 signal and the L5 signal respectively, to obtain satellite data 1 corresponding to the L1 signal and satellite data 2 corresponding to the L5 signal, and input the satellite data 1 and the satellite data 2 to the main control chip 306.

[0056] The main control chip 306 is configured to determine positioning information 1 according to the satellite data 1, determine positioning information 2 according to the satellite data 2, and correct the positioning information 1 using the positioning information 2, to obtain the positioning information of the head-mounted device.

[0057] Optionally, the head-mounted device can further include a display module and / or a microphone (not shown in the figure), which can be connected with the first circuit board 30. The display module is configured to display the positioning information determined by the first circuit board 30, and the microphone is configured to play the positioning information determined by the first circuit board 30 by voice.

[0058] At present, when an electronic device (such as a mobile phone, a smart watch, etc.) is positioning, the positioning accuracy can be affected by the antenna direction, resulting in low positioning accuracy. For example, when a smart watch is positioning, the antenna direction will change with the swing of the arm, resulting in low signal-to-noise ratio of the positioning signal received by the antenna, and thus low positioning accuracy. For another example, when a mobile phone is positioning, if the mobile phone is held in the hand, the antenna direction will change with the swing of the arm, resulting in low signal-to-noise ratio of the positioning signal received by the antenna; if the mobile phone is put in the pocket, if the antenna is downward, it will also affect the reception of the positioning signal by the mobile phone, resulting in low positioning accuracy. Therefore, the head-mounted device can optionally send the positioning information to other electronic devices (such as a first device) to assist the first device in positioning. For example, the head-mounted device can send the positioning information to the first device through a Bluetooth (BT) connection, a Bluetooth low energy (BLE) connection or a Starlink connection, etc. The first device can be a mobile phone and other wearable devices, such as a smart watch, a bracelet, etc.

[0059] For example, the head-mounted device sends the positioning information to the first device through Bluetooth connection, the first circuit board 30 can further include a Bluetooth signal processing chip 307 and a filter 308. The Bluetooth signal processing chip 307 can be independently arranged, or integrated with the main control chip 306 and / or the positioning signal processing chip 305 in the same chip, which is not limited in the embodiments of the present application.

[0060] After the main control chip 306 determines the positioning information, the main control chip 306 can input the positioning information to the Bluetooth signal processing chip 307.

[0061] The Bluetooth signal processing chip 307 is configured to generate a Bluetooth signal, for example, to perform encoding, modulation, frequency conversion processing, to generate a Bluetooth signal, the Bluetooth signal including the positioning information determined by the main control chip 306, and input the generated Bluetooth signal to the filter 308.

[0062] The filter 308 is configured to filter the Bluetooth signal, and input the filtered Bluetooth signal to the combiner 301.

[0063] The combiner 301 is configured to filter the Bluetooth signal, and send the filtered Bluetooth signal to the first device through the first antenna branch 10 and / or the second antenna branch 11.

[0064] Optionally, the head-mounted device can further include a third antenna branch (not shown in the figure) for communication with other devices, for example, for receiving or sending Bluetooth signals.

[0065] It can be understood that when the head-mounted device assists the first device in positioning, the head-mounted device can send the positioning information to the first device, or can send satellite data (for example, satellite data 1 and satellite data 2) to the first device. For example, after the main control chip 306 receives the satellite data 1 and the satellite data 2 from the positioning signal processing chip 305, the main control chip 306 can input the satellite data 1 and the satellite data 2 to the Bluetooth signal processing chip 307. The Bluetooth signal processing chip 307 generates a Bluetooth signal containing the satellite data 1 and the satellite data 2, and sends the Bluetooth signal to the first device after filtering by the filter 308 and the combiner 301. When the first device receives the satellite data 1 and the satellite data 2, the first device determines the positioning information according to the satellite data 1 and the satellite data 2. In this way, the computing burden of the head-mounted device can be reduced, and the power consumption of the head-mounted device can be reduced. The way in which the first device determines the positioning information according to the satellite data 1 and the satellite data 2 can refer to the way in which the main control chip 306 determines the positioning information according to the positioning information 1 and the positioning information 2, which will not be described herein.

[0066] With the above embodiments and related drawings, the present embodiments provide a positioning method, which can be implemented by the head-mounted device as shown in FIG. 1 or FIG. 2. Please refer to FIG. 5, which is a flowchart of the method. In FIG. 5, the head-mounted device assists the first device in positioning is taken as an example.

[0067] S501: The head-mounted device receives a positioning signal.

[0068] The head-mounted device can receive the positioning signal through the antenna branches (e.g., the first antenna branch 10 and the second antenna branch 11 as shown in FIG. 1) included therein. The first antenna branch 10 and the second antenna branch radiate electromagnetic waves with the same polarization characteristics as the polarization characteristics of the electromagnetic waves used to carry the positioning signal.

[0069] S502: The head-mounted device determines positioning information according to the positioning signal.

[0070] For example, the head-mounted device can determine the positioning information through the first circuit board 30 receiving the positioning signal by the first antenna branch 10 and the second antenna branch 11. The determination process can refer to the process of determining the positioning information in FIG. 4, which will not be repeated here.

[0071] Optionally, after determining the positioning information, the head-mounted device can also play the positioning information through the aforementioned microphone, or display the positioning information through the aforementioned display module, or perform S503 to assist the first device in positioning.

[0072] It can be understood that when the head-mounted device assists the first device in positioning, it can also send the received positioning signal to the first device, i.e., not performing S502, and the first device determines the positioning information according to the positioning signal. The present embodiments do not limit the device that determines the positioning information when the head-mounted device assists the first device in positioning. The process in which the first device determines the positioning information according to the positioning signal can refer to the process of determining the positioning information in FIG. 4, which will not be repeated here.
