Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, fig. 1 is a schematic application environment diagram of a positioning method according to an embodiment of the present application. As shown in fig. 1, the application environment includes a first terminal 110 and a second terminal 120.
In the related art, the first terminal 110 transmits a positioning signal, and the second terminal 120 receives the positioning signal, thereby recognizing a relative positional relationship between the first terminal 110 and the second terminal 120. However, if the second terminal 120 is interfered, the second terminal 120 may receive the positioning signal transmitted by the non-cooperative third terminal, or even the positioning signal cannot be received, which may affect the accuracy of the terminal positioning.
The first terminal 110 is a wearable display device, and the second terminal 120 is a control handle.
Wherein the wearable display device is configured to perform a visual display as a medium for user interaction with the virtual display. The control handle is a matched product with the wearable display device and is used for receiving touch control information of a user, the user inputs the touch control information through holding the control handle, and virtual display displayed by the wearable display device is correspondingly changed.
Specifically, wearable display device can be to handheld control handle transmission locating signal, and control handle can receive the locating signal of wearable display device transmission to according to wearable display device transmission locating signal's transmission information, and control handle receives the receiving information of the locating signal of wearable display device transmission, can determine the relative position relation between wearable display device and the control handle, thereby confirm the handheld touch-control information of controlling handle of user, thereby make the virtual display correspondence that wearable display device shows change.
For example, the ultrasonic wave is exemplified as the positioning signal. Generally, a wearable display device is provided with three ultrasonic receiving sensors, a control handle is provided with six ultrasonic receiving sensors and three receiving sensors, and the three receiving sensors respectively correspond to 120-degree ranges of the front, the left side and the right side so as to realize 360-degree coverage; the six receiving sensors are distributed around the handle in a circle respectively to ensure that more than 4 receiving sensors can be positioned in the angle coverage range of the receiving sensors at any angle; the wearable helmet display device comprises an ultrasonic positioning principle, a single-point transmitting device and four-point receiving devices, wherein the distances from a sine wave transmitting single point to the four receiving points are calculated through the flight time of sound waves in the space, so that the angles and the relative space distances of relative positions are calculated, and the tracking of the corresponding control handle space direction and the motion trail by the wearable helmet display is realized.
However, if the wearable display device and the control handle are used in a place of sale, in a scene such as a multi-user gathering activity and an exhibition-type large-scale field immersive experience, due to the fact that other wearable display devices and other products of the same type as the control handle are too concentrated, the control handle receives interference, it is impossible to determine that the positioning signal received by the control handle is transmitted by the matched wearable display device or transmitted by other non-matched wearable display devices, and therefore identification of the relative position relationship between the wearable display device and the control handle is not accurate enough, and experience of a user on virtual display is reduced.
Therefore, the embodiment of the application provides a positioning method, a positioning device, a positioning system, a terminal, a storage medium and a program product, so as to improve the accuracy of terminal positioning.
It should be noted that, the steps of the positioning method provided in this embodiment may be executed by the first terminal 110 or the second terminal 120, or may be executed by a control terminal connected to the first terminal 110 and the second terminal 120, which is not limited in this embodiment.
Referring to fig. 2, fig. 2 is a schematic flowchart of a positioning method according to an embodiment of the present disclosure. This method is applied to the positioning system shown in fig. 1. As shown in fig. 2, the positioning method includes:
The target receiving end may be one of the first terminal and the second terminal. The first positioning signal is a positioning signal received by a target receiving end. Specifically, the first positioning signal may be a positioning signal transmitted by a target transmitting end that is matched with the target receiving end, or may be a positioning signal transmitted by a non-matched third terminal, and is related to an actual signal receiving situation, which is not limited in this embodiment. The target transmitting terminal is the other one of the first terminal and the second terminal. If the first terminal is a target receiving end, the second terminal is a target transmitting end; and if the second terminal is the target receiving end, the first terminal is the target transmitting end. Optionally, any one of the first terminal and the second terminal in this embodiment may be a target receiving end. Similarly, any one of the first terminal and the second terminal can be used as a target transmitting terminal.
In this embodiment, the first terminal and the second terminal are configured to perform the transceiving processing of the positioning signal simultaneously. Specifically, the first terminal has the capability of transmitting the positioning signal and the capability of receiving the positioning signal; the second terminal also has the capability of transmitting positioning signals and the capability of receiving positioning signals. The first terminal and the second terminal are used for simultaneously performing transceiving processing of the positioning signals, that is, at the same time, the first terminal and the second terminal simultaneously transmit the positioning signals to each other, and meanwhile, the first terminal and the second terminal wait for receiving the positioning signals transmitted by each other.
And step 220, judging whether the first positioning signal is a target positioning signal transmitted by a target transmitting terminal.
In this embodiment, if yes, step 230 is executed.
The relative position relationship may include, but is not limited to, a distance relationship, an angle relationship, and the like, and the embodiment is not limited thereto. Optionally, the transmission information includes, but is not limited to, at least one of transmission intensity and transmission time. Similarly, the receiving information includes, but is not limited to, at least one of receiving strength and receiving time. Alternatively, the transmission intensity may be determined by the power of the target transmitting terminal transmitting the positioning signal.
In this embodiment, if the first positioning signal is a target positioning signal transmitted by a target transmitting end, positioning processing is performed according to transmission information of the first positioning signal transmitted by the target transmitting end and receiving information of the first positioning signal received by a target receiving end, so as to obtain a relative position relationship between the first terminal and the second terminal.
Optionally, the transmission information may include, but is not limited to, transmission intensity, transmission time, and the like. The reception information may include, but is not limited to, reception intensity, reception time, and the like.
According to the technical scheme of the embodiment, as the first terminal and the second terminal are used for simultaneously receiving and sending the positioning signals, if any one of the first terminal and the second terminal receives the positioning signals transmitted by the other terminal, the positioning processing can be carried out to obtain the relative position relationship between the first terminal and the second terminal, even if one of the first terminal and the second terminal is interfered, the identification of the relative position relationship between the first terminal and the second terminal cannot be influenced, and the technical effect of improving the positioning accuracy of the terminal is improved.
The first positioning signal received by only one of the first terminal and the second terminal may be acquired. If the first positioning signal received by one party is acquired and transmitted by the other party, the positioning processing is directly carried out; and if the acquired first positioning signal received by one party is the positioning signal transmitted by the third terminal, acquiring the first positioning signal received by the other party again, and performing positioning processing.
In addition, the positioning signals received by the first terminal and the second terminal can also be acquired simultaneously. If one of the parties receives the first positioning signal transmitted by the other party, positioning processing is carried out based on the received information of the first positioning signal transmitted by the other party and the transmitted information of the first positioning signal transmitted by the other party. If both sides receive the first positioning signal transmitted by the other side, positioning processing is carried out according to the first transmitting information of the first positioning signal transmitted by the first terminal, the first receiving information of the first positioning signal received by the second terminal, the second transmitting information of the first positioning signal transmitted by the second terminal and the second receiving information of the first positioning signal received by the first terminal.
It can be understood that, if both sides receive the first positioning signal transmitted by the other side, the positioning process is performed according to the first transmission information of the first positioning signal transmitted by the first terminal, the first reception information of the first positioning signal received by the second terminal, the second transmission information of the first positioning signal transmitted by the second terminal, and the second reception information of the first positioning signal received by the first terminal, because more information is processed in the positioning process, the result of the positioning of the terminal is more accurate.
In one possible implementation, if a plurality of first positioning signals are received by the target receiving end, determining whether the first positioning signals are target positioning signals or not for each received first positioning signal; if yes, positioning processing is carried out according to the transmitting information of the target positioning signal transmitted by the target transmitting end and the receiving information of the target positioning signal received by the target receiving end.
In one possible implementation, the determining whether the first positioning signal is a target positioning signal transmitted by a target transmitting end includes:
identifying a first signal characteristic of the first positioning signal;
and if the first signal characteristic is consistent with the target signal characteristic corresponding to the target positioning signal, the first positioning signal is a target positioning signal transmitted by a target transmitting terminal.
Wherein the first signal characteristic refers to a characteristic of the first positioning signal. Optionally, the first signal characteristic may be a channel occupied by the first positioning signal, and may also be a receiving interval time of the first positioning signal, which is not limited in this embodiment. Target signal characteristics refer to characteristics of a target-locating signal. Accordingly, the target signal characteristic may be a channel occupied by the target positioning signal, or may be a transmission interval of the target positioning signal.
In this embodiment, if the first signal characteristic is consistent with the target signal characteristic, it may be determined that the first positioning signal is a target positioning signal transmitted by the target transmitting end.
Referring to fig. 3, fig. 3 is a schematic flow chart of another positioning method according to an embodiment of the present disclosure. The embodiment is suitable for the situation that the first terminal and the second terminal are respectively controlled to transmit the positioning signals. In one embodiment, as shown in fig. 3, the positioning method includes:
step 310, obtaining a second signal characteristic of each second positioning signal, where the second positioning signal includes a positioning signal transmitted by a third terminal monitored within a preset range of the first terminal and/or within a preset range of the second terminal.
The third terminal is a terminal which can transmit the positioning signal and is not matched with the first terminal and the second terminal. It should be noted that the third terminal does not refer to a specific terminal. All terminals which are not matched with the first terminal and the third terminal and can transmit positioning signals to cause interference to the first terminal and the second terminal can be considered as the third terminal. The second positioning signal refers to a positioning signal transmitted by the third terminal which is monitored. In particular, the second positioning signal may be considered an interference signal for the first terminal and the second terminal.
In this embodiment, the monitoring may be performed only on the positioning signal transmitted by the third terminal within the preset range of the first terminal, may also refer to monitoring the positioning signal transmitted by the third terminal within the preset range of the second terminal, and may also be performed on the positioning signals transmitted by the third terminals within the preset range of the first terminal and the preset range of the second terminal simultaneously, which is not limited in this embodiment.
Optionally, the positioning signal transmitted by the third terminal may be monitored by receiving sensors disposed on the first terminal and the second terminal. The size of the preset range may depend on the range that the receiving sensor can listen to.
It should be noted that, the positioning signal transmitted by the third terminal may be monitored when the first terminal and the second terminal are in the standby state; for example, the monitoring of the positioning signal transmitted by the third terminal may be completed when the first terminal and the second terminal are powered on or initialized. In addition, the positioning signal transmitted by the third terminal may also be monitored when the first terminal and the second terminal are in an operating state, which is not limited in this embodiment.
In this embodiment, the target signal characteristic is used to indicate a reduction in interference of the positioning signal interacted between the first terminal and the second terminal.
And step 330, respectively controlling the first terminal and the second terminal to transmit positioning signals according to the target signal characteristics.
In this embodiment, the first terminal and the second terminal are respectively controlled to transmit the positioning signals according to the target signal characteristics, so that the signal characteristics of the target positioning signals transmitted by the first terminal and the second terminal can be consistent with the target signal characteristics.
Optionally, the target signal characteristic in this embodiment may include, but is not limited to, at least one of a channel occupied by the target positioning signal and a transmission interval time of the target positioning signal.
It should be noted that, if the target signal characteristic is the transmission interval time, the frequencies of the signals transmitted by the first terminal and the second terminal can be adjusted by adjusting the duty cycles of the signal transmissions, so that the signal characteristics of the positioning signals transmitted by the first terminal and the second terminal are presented as the target signal characteristic.
And step 340, acquiring a first positioning signal received by the target receiving end.
And 360, judging whether the first signal characteristic is consistent with the target signal characteristic.
In this embodiment, if yes, step 370 is executed.
In this embodiment, if the first signal characteristic of the first positioning signal is consistent with the target signal characteristic of the target positioning signal, the positioning processing is performed according to the transmission information of the first positioning signal transmitted by the target transmitting terminal and the receiving information of the first positioning signal received by the target receiving terminal.
In some instances of the examples, the signal characteristics of the target-locating signal are all fixed. However, the signal characteristics of the target positioning signal are fixed, if the third terminals around the first terminal and the second terminal are of the same type, the third terminal may also transmit the positioning signal with the same signal characteristics, and at this time, the first positioning signal received by one of the first terminal and the second terminal cannot be known to be transmitted by the other one of the first terminal and the second terminal, or transmitted by the third terminal of a non-matched product of the same type, so that the accuracy of terminal positioning is reduced.
According to the technical scheme of the embodiment, the second positioning signal transmitted by the third terminal in the preset range of the first terminal and/or the preset range of the second terminal is monitored, and the target signal characteristic is determined according to the second signal characteristic of the second positioning signal, so that the first terminal and the second terminal are controlled to transmit the positioning signal according to the target signal characteristic.
The following embodiments further illustrate how to determine the target signal characteristics based on any of the above embodiments.
Referring to fig. 4, fig. 4 is a schematic flowchart of determining a target signal characteristic according to an embodiment of the present application. In one embodiment, the determining the target signal characteristic according to the second signal characteristic of each second positioning signal includes:
step 410, determining candidate channels in a plurality of preset channels according to channels occupied by the second positioning signals, where the number of the second positioning signals in the candidate channels is less than or equal to the number of the second positioning signals in any one of the preset channels.
In the present embodiment, it is assumed that the plurality of preset channels includes channel 1, channel 2, and channel 3, for example. If the number of the second positioning signals in the channel 1 is less than the number of the second positioning signals in the channel 2 and less than the number of the second positioning signals in the channel 3, the channel 1 is a candidate channel; if the number of the second positioning signals in the channel 1 is equal to the number of the second positioning signals in the channel 2 < the number of the second positioning signals in the channel 3, the channel 1 and the channel 2 are candidate channels.
It should be noted that the frequency band of the preset channel may be set as required. For example, the frequency band of channel 1 is 1MHz (hertz) -1.5 MHz; the frequency band of the channel 2 is 1.5MHz (Hertz) -2 MHz; the frequency band of the channel 3 is 2MHz (hertz) -2.5MHz, and the specific number of the preset channels and the frequency band interval of the preset channels are not particularly limited herein.
In one possible implementation, before determining the candidate channel of the multiple preset channels according to the channel occupied by each second positioning signal, the method includes:
acquiring the signal frequency of each first positioning signal and the channel frequency band corresponding to each preset channel, wherein the channel frequency bands between any two preset channels are not overlapped with each other; and determining a channel occupied by each first positioning signal according to the channel frequency band matched with the signal frequency of each first positioning signal.
In this embodiment, for example, assuming that the plurality of preset channels includes channel 1, channel 2 and channel 3, a plurality of second positioning signals, which are signal a, signal B and signal C, are listened to. The frequency range of the channel 1 is 1MHz (Hertz) -1.5 MHz; the frequency band of the channel 2 is 1.5MHz (Hertz) -2 MHz; the frequency band of the channel 3 is 2MHz (Hertz) -2.5 MHz. If the frequency of the signal A is 1.3MHz, the signal A occupies a channel 1; if the frequency of the signal B is 1.8MHz, the signal B occupies a channel 2; signal C has a frequency of 2.2MHz, and signal C occupies channel 3.
In this embodiment, one of the candidate channels may be used as the target channel occupied by the target positioning signal. For example, if the candidate channel includes channel 1, then channel 1 is taken as the target channel; if the candidate channels include channel 1 and channel 2, one of channel 1 and channel 2 is taken as the target channel.
It can be understood that, by selecting the channel with the least number of interference signals as the signal characteristic of the target positioning signal for positioning between the first terminal and the second terminal, the number of interference signals in the channel occupied by the target positioning signal is the least, so that the possibility of being interfered is as low as possible, and the accuracy of positioning the terminal is improved.
In a possible implementation, the selecting one of the candidate channels as a target channel occupied by the target positioning signal includes:
and if the number of the second positioning signals in the candidate channels is zero, selecting any one of the candidate channels as the target channel.
In this embodiment, if the number of second positioning signals in the candidate channels is zero, interference of each candidate channel is almost zero regardless of the number of candidate channels, and any one of the candidate channels may be set as the target channel.
In one possible implementation, if the number of candidate channels is one, the candidate channel may be used as the target channel.
In a possible implementation, the selecting one of the candidate channels as a target channel occupied by the target positioning signal includes:
if the candidate channels are multiple and the number of the second positioning signals in the candidate channels is greater than zero, selecting one of the candidate channels as the target channel according to the signal strength of each second positioning signal in each candidate channel.
Wherein the average value of the signal strength of the second positioning signal in the target channel is less than or equal to the average value of the signal strength of the second positioning signal in any one of the candidate channels; and/or the signal strength of each second positioning signal in the target channel is less than or equal to the signal strength of each second positioning signal in any candidate channel.
In this embodiment, if there are a plurality of candidate channels and the number of second positioning signals in the candidate channels is greater than zero, in order to minimize interference, it is necessary to select one of the candidate channels as the target channel according to the signal strength of each second positioning signal in each candidate channel.
Optionally, the signal strength of each second positioning signal in each candidate channel may be detected first, and then the average value of the signal strengths of all the second positioning signals in each candidate channel is determined, so that the candidate channel with the smallest signal average value is selected as the target channel.
In addition, it may also be determined whether there is a preset candidate channel whose maximum signal strength is smaller than the minimum signal strengths of other candidate channels, and if so, the signal strength of the interference signal of the preset candidate channel is the minimum, so that the preset candidate channel is taken as the target channel. If the preset candidate channel does not exist, the signal intensity average value of all the second positioning signals in each candidate channel is determined, and therefore the candidate channel with the minimum signal average value is selected as the target channel.
In one possible embodiment, the second signal characteristic includes a listening interval time, where the listening interval time is an interval time between two consecutive times of listening to the same second positioning signal, and the determining the target signal characteristic according to the second signal characteristic of each second positioning signal includes:
and determining the signal transmission interval time of the target positioning signal according to the monitoring interval time of each second positioning signal, wherein the signal transmission interval time is different from the monitoring interval time, and the signal transmission interval is one item of the characteristics of the target signal.
In this embodiment, the signal transmission interval time and the listening interval time of the target positioning signal are distinguished, and then whether the first positioning signal is the target positioning signal or not can be determined through the received reception interval time of the first positioning signal. Specifically, if the receiving interval between the current reception of the first positioning signal and the last reception of the target positioning signal is the determined signal transmitting interval, it may be determined that the first positioning signal is the target positioning signal.
Illustratively, the target transmitting end sends the positioning signal at an interval of 10us, and if the receiving interval between the first positioning signal received by the target receiving end and the last target positioning signal received is 10us, it may be determined that the first positioning signal is the target positioning signal transmitted by the target transmitting end, so as to perform the positioning processing.
Alternatively, the signal transmission interval time may be set to be smaller than the listening interval time. Therefore, accurate positioning can be guaranteed, and the relative position relation between the first terminal and the second terminal can be updated in time.
The determination of the same second positioning signal may be determined by the frequency of the second positioning signal, and if two second positioning signals with the same frequency are received, the two second positioning signals may be regarded as the same second positioning signal. In addition, the determination may also be performed through a channel occupied by the second positioning signal, for example, two second positioning signals occupying the same channel may be regarded as the same second positioning signal, as long as whether the two second positioning signals are the same second positioning signal can be determined through a specific flag feature, and the embodiment does not limit how to determine whether the two second positioning signals are the same second positioning signal.
In one possible embodiment, the target signal characteristic includes a target channel and a signal transmission interval time.
In this embodiment, all the first signal characteristics of the first positioning signal may satisfy the corresponding target signal characteristics, and the first positioning signal is considered as the target positioning signal.
