Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The user positioning method provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the base station 104 via a network. The data storage system may store data that the base station 104 needs to process. The data storage system may be integrated on the base station 104 or may be located on the cloud or other network server. The terminal 102 determines at least two reference points corresponding to the to-be-positioned point, and performs position mapping processing on the reference points and the corresponding base stations based on the position information of the to-be-positioned point, and further determines the position information of the to-be-positioned point according to the position information of the base stations corresponding to the to-be-positioned point and the position information of the base stations corresponding to the mapped reference points. The terminal 102 may include, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices, and portable wearable devices, where the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The base station 104 may be implemented as a stand-alone base station or as a cluster of base stations comprising a plurality of base stations.
In one embodiment, as shown in fig. 2, a user positioning method is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:
step 201, determining at least two reference points corresponding to the to-be-positioned point according to the movement track of the user.
The to-be-positioned point refers to a point which needs to be positioned currently, and the distance between the to-be-positioned point and a certain base station is known information, or the distance between the to-be-positioned point and a corresponding base station can be obtained in some modes so as to ensure that the position information of the to-be-positioned point can be successfully determined subsequently. The base station corresponding to the to-be-positioned point may be a base station that currently provides a service for the terminal, or a base station that the terminal may receive a signal sent by the terminal, and so on.
At least two reference points corresponding to the to-be-positioned points and the to-be-positioned points are positioned on the same moving track, and the distance between each reference point and the corresponding base station can be determined; thus, it can be understood that: two reference points can be arbitrarily selected on the moving track, or a point which can determine the distance between the moving track and the base station on the moving track containing the to-be-positioned point is the reference point.
In one embodiment of the present application, when at least two reference points corresponding to a to-be-positioned point need to be determined, it may be verified whether the distance between the terminal and the base station can be determined when the terminal moves in the movement track, and if a certain point in the movement track of the terminal determines the distance between the terminal and the base station, the point is taken as the reference point; if a certain point in the moving track of the terminal cannot determine the distance between the terminal and the base station, the point is not a reference point.
It should be noted that, the terminal may determine the transmission time of the reference signal according to the time when the base station transmits the reference signal and the time when the terminal receives the reference signal by receiving the reference signal fed back by the base station, and further calculate the transmission distance of the reference signal according to the transmission time of the reference signal and the transmission speed of the reference signal, where the transmission distance is the distance between the reference point and the base station.
In an embodiment of the present application, if the terminal receives the reference signal fed back by the base station when moving to a certain point in the moving track, the distance between the reference point and the base station may be calculated according to the time when the base station transmits the reference signal and the time when the terminal receives the reference signal, and then, the point where the reference signal fed back by the base station is received may be used as the reference point.
Step 202, performing position mapping processing on each reference point and the corresponding base station according to the position information of the to-be-positioned point, and obtaining the base station position information corresponding to each mapped reference point.
The base station position information corresponding to each mapped reference point refers to position information corresponding to the base station corresponding to each reference point after mapping processing.
It should be noted that, the position mapping processing is performed on each reference point and the corresponding base station so as to make each mapped reference point coincide with the to-be-positioned point, so that when each mapped reference point coincides with the to-be-positioned point, the mapping processing of each reference point and the corresponding base station is completed.
And when the position mapping processing is carried out on each reference point and the corresponding base station, the position corresponding relation between each reference point and the base station before the mapping processing is ensured to be the same as the position corresponding relation between each reference point and the base station after the mapping processing, and further, the accuracy of the position information of the to-be-positioned point is ensured to be determined subsequently.
In one embodiment of the present application, when position mapping processing needs to be performed on each reference point and a corresponding base station, a position correspondence relationship between each reference point and the base station is predetermined, each reference point and the base station are moved according to a movement track of a user, so that each reference point is moved to a to-be-positioned point, when each reference point and the base station are moved, the position correspondence relationship between each reference point and the base station needs to be maintained, and when each mapped reference point is coincident with the to-be-positioned point, the mapping processing of each reference point and the corresponding base station is completed.
For example, as shown in fig. 3, after determining the movement track of the user, determining the reference point a, the reference point B and the to-be-positioned point C on the movement track, when the position mapping process is required to be performed on each reference point and the corresponding base station, determining the position correspondence between the reference point a and the base station a, and the position correspondence between the reference point B and the base station B, and based on the position correspondence between the reference point a and the base station a and the position correspondence between the reference point B and the base station B, each reference point a, the reference point B, the base station a and the base station B move according to the movement track of the user, and when the reference point a and the reference point B are coincident with the to-be-positioned point C, the mapping process of the reference point a, the reference point B, the base station a and the base station B is completed.
The position corresponding relation between the reference point A and the base station A represents a circle obtained by taking the base station A as a circle center and taking the distance between the reference point A and the base station A as a radius; the position correspondence relationship between the reference point B and the base station B indicates a circle obtained by taking the base station B as a center and the distance between the reference point B and the base station B as a radius.
Wherein, base station A in FIG. 3 1 And base station B 1 The mapping processing positions of the base station A and the base station B are obtained, and after the mapping processing of the reference point A, the reference point B, the base station A and the base station B is completed, the reference point A and the reference point B are overlapped with the to-be-positioned point C, so that the position corresponding relation between the reference point A and the base station A is equal to that between the to-be-positioned point C and the base station A 1 The position corresponding relation between the two; the position correspondence between the reference point B and the base station B is equal to that between the undetermined point C and the base station B 1 Positional correspondence between the two.
Further, when the base station location information corresponding to each mapped reference point needs to be determined, the following may be specifically included: because each reference point and the corresponding base station need to be mapped to the to-be-positioned point when the position mapping processing is carried out on each reference point and the corresponding base station, and the position corresponding relation between each reference point and the base station in the mapping process is kept unchanged, the position information of the base station corresponding to each reference point can be changed based on the position information change condition of each reference point relative to the to-be-positioned point, and the position information of the base station corresponding to each reference point after mapping is determined.
For example, if the position information of the reference point is known to be represented by coordinates as (1, 1), the position information of the to-be-positioned point is known to be represented by coordinates as (0, 0), the position information change condition of the reference point relative to the to-be-positioned point is determined as follows: the abscissa is subtracted by one, so that the base station position information corresponding to the mapped reference point is equal to the base station position information corresponding to the reference point before mapping, and if the base station position information corresponding to the reference point before mapping is represented by coordinates as (3, 3), the base station position information corresponding to the reference point after mapping is represented by coordinates as (2, 2).
Step 203, determining the position information of the to-be-positioned point according to the position information of the base station corresponding to the to-be-positioned point and the mapped position information of the base station corresponding to each reference point.
The base station position information corresponding to the to-be-positioned point refers to the position information of the base station corresponding to the to-be-positioned point.
When the position information of the to-be-positioned point needs to be determined, the distance between the to-be-positioned point and the corresponding base station and the distance between each reference point and the corresponding base station can be predetermined; and determining the position information of the to-be-positioned point according to the distance between the to-be-positioned point and the corresponding base station, the distance between each reference point and the corresponding base station, the base station position information corresponding to the to-be-positioned point and the mapped base station position information corresponding to each reference point.
Further, after determining the distance between the to-be-positioned point and the corresponding base station, the distance between each reference point and the corresponding base station, the base station position information corresponding to the to-be-positioned point, and the mapped base station position information corresponding to each reference point, the data may be subjected to positioning operation based on a Multi-Round Trip Time (Multi-path Trip Time) positioning method, where the obtained result is the position information of the to-be-positioned point.
For example, as shown in fig. 4, fig. 4 includes a base station a after mapping 1 Base station B 1 And the base station C is a base station corresponding to the to-be-positioned point C. When the position information of the to-be-positioned point needs to be determined, the distance between the to-be-positioned point C and the base station A can be determined 1 Distance from pending site C, base station B 1 Distance from the pending site C and determining base station A 1 Base station position information of (B) base station B 1 Base station position information of base station C and base station position information of base station C. Furthermore, based on the Multi-RTT positioning method, base station A based on the distance between the to-be-positioned point C and base station C 1 Distance from pending site C, base station B 1 Distance from pending site C, base station a 1 Base station position information of (B) base station B 1 And base station position information of base station C, determining position information of the to-be-positioned point.
Because each reference point and the corresponding base station need to be mapped to the to-be-positioned point when the position mapping processing is carried out on each reference point and the corresponding base station, and the position corresponding relation between each reference point and the base station in the mapping process is kept unchanged, the base station A 1 Distance from pending site C and base station B 1 The distance between the base station and the to-be-positioned point C is the distance between each reference point and the corresponding base station.
According to the user positioning method, the base station position information corresponding to each mapped reference point is obtained according to at least two reference points in the moving track and the position information of the to-be-positioned point; and determining the position information of the to-be-positioned point according to the position information of the base station corresponding to the to-be-positioned point and the mapped position information of the base station corresponding to each reference point. Because each reference point in the moving track is mapped to the to-be-positioned point in the moving track in the process of mapping each reference point and the corresponding base station, the position information of the to-be-positioned point is determined according to the position information of the base station corresponding to the to-be-positioned point and the position information of the base station corresponding to each mapped reference point.
Along with the continuous improvement of the requirement of the user on the positioning accuracy, the dead reckoning method of the pedestrian cannot meet the requirement of the user on the positioning accuracy, so, in order to solve the problem of lower positioning accuracy when the user is positioned by the dead reckoning method of the pedestrian, the terminal of the embodiment can determine the position information of the to-be-positioned point according to the position information of the base station corresponding to the to-be-positioned point and the position information of the base station corresponding to each mapped reference point in a manner shown in fig. 5, and specifically comprises the following steps:
Step 501, distance information is acquired.
The distance information comprises the distance between the to-be-positioned point and the corresponding base station and the distance between each reference point and the corresponding base station.
It should be noted that, when the distance information needs to be acquired, the following may be specifically included: acquiring reference signals corresponding to all reference points and reference signals corresponding to the to-be-positioned points respectively; and determining the distance between each reference point and the corresponding base station according to the reference signals corresponding to each reference point, and determining the distance between the to-be-positioned point and the corresponding base station according to the reference signals corresponding to the to-be-positioned point respectively.
In one embodiment of the present application, when determining the distance between the reference point and the corresponding base station and the distance between the to-be-determined point and the corresponding base station according to the reference signal, the time when the base station transmits the reference signal and the time when the terminal receives the reference signal may be determined based on the reference signal, and the transmission time of the reference signal may be determined according to the time when the base station transmits the reference signal and the time when the terminal receives the reference signal; and multiplying the transmission speed of the reference signal and the transmission time of the reference signal to obtain a transmission distance of the reference signal, wherein the transmission distances of the reference signal at different positions are the distances between the reference point and the corresponding base station and the distances between the to-be-positioned point and the corresponding base station.
The reference signals corresponding to the reference points are reference signals sent to different reference points by the same base station, and/or reference signals sent to the same reference point by different base stations, and/or reference signals sent to different reference points by different base stations.
As an implementation manner, as shown in fig. 6, the base station D in fig. 6 transmits reference signals for the reference point 1 and the reference point 2, respectively; wherein, base station D 1 For the base station position information corresponding to the mapped reference point 1, the base station D 2 And the base station position information corresponding to the mapped reference point 2.
As an implementation manner, as shown in fig. 7, base station E and base station F both transmit reference signals for reference point 3; wherein, base station E 1 For the base station position information corresponding to the mapped reference point 3, the base station F 1 Corresponding to the mapped reference point 3Is provided.
As an implementation manner, as shown in fig. 8, the base station M and the base station N in fig. 8 send reference signals for the reference point 4 and the reference point 5, respectively; wherein, base station M 1 For the base station position information corresponding to the mapped reference point 4, the base station N 1 And the base station position information corresponding to the mapped reference point 5.
Step 502, determining the position information of the to-be-positioned point according to the position information of the base station corresponding to the to-be-positioned point, the mapped position information of the base station corresponding to each reference point and the distance information.
When determining the position information of the to-be-positioned point, the positioning operation may be performed based on the base station position information corresponding to the to-be-positioned point, the base station position information corresponding to each mapped reference point, and the distance information (the distance between the to-be-positioned point and the corresponding base station in the distance information, and the distance between each reference point and the corresponding base station), where the obtained result is the position information of the to-be-positioned point.
According to the user positioning method, the position information of the to-be-positioned point is determined according to the position information of the base station corresponding to the to-be-positioned point, the mapped base station position information corresponding to each reference point and the mapped distance information, and the base station position information corresponding to the to-be-positioned point and the mapped base station position information corresponding to each reference point are combined, so that the situation that the user cannot be accurately obtained by positioning by a pedestrian dead reckoning method is avoided, and the accuracy of determining the to-be-positioned point is improved.
In one embodiment, the location information of the base station corresponding to each reference point after mapping is obtained at the location where each reference point is mapped to the positioning point, where as shown in fig. 9, the method includes:
step 901, mapping each reference point to the position of the positioning point according to the position information of the to-be-positioned point, and obtaining the position information of each mapped reference point.
Wherein, because the mapping process needs to map each reference point to the position of the positioning point, the position information of each mapped reference point is the same as the position information of the position to be positioned.
If the position information of the to-be-positioned point and the position information of each reference point are represented by coordinates, mapping each reference point to the position of the positioning point, which is the same as the coordinates of each reference point by performing addition and subtraction processing on the horizontal and vertical coordinates, so that the coordinates of the processed reference point are the same as the coordinates of the to-be-positioned point.
For example, if the coordinates of a certain reference point are represented as (5, 4) and the coordinates of the to-be-positioned point are represented as (3, 3), mapping each reference point to the position of the positioning point is equivalent to subtracting 2 from the abscissa of the reference point and subtracting 1 from the ordinate of the reference point, so as to obtain the position information of the mapped reference point as (3, 3).
The coordinates of each reference point can be determined based on the dead reckoning method of the pedestrian according to the relative distance of each reference point on the moving track and the distance between each reference point and the corresponding base station.
Step 902, determining the base station position information corresponding to each mapped reference point according to the position information of each mapped reference point and the position correspondence between the reference point and the base station.
The distance between each reference point and the corresponding base station on the moving track can be obtained, and then the position corresponding relation between the reference points and the base stations is determined according to the distance between each reference point and the corresponding base station on the moving track.
Further, the position correspondence between the reference point and the base station may be understood as that a circle is drawn by taking the base station as a center of a circle and taking the distance between the reference point and the corresponding base station as a radius, and the obtained circle with the center of the circle is the position correspondence between the reference point and the base station, and the position correspondence between the reference point and the base station indicates that the position of the reference point is located at any point on the circle taking the base station as the center of the circle and taking the distance between the reference point and the corresponding base station as the radius.
In one embodiment of the present application, when determining the base station corresponding to each mapped reference point, the base stations are used as circle centers, and the circle containing the reference point (that is, the position corresponding relation between each reference point and the base station) is mapped as a whole, so that the reference point in each circle coincides with each mapped reference point (that is, the reference point in each circle coincides with the to-be-positioned point), therefore, the circles containing the reference point intersect at the to-be-positioned point with each base station as the circle center, and at this time, the circle center corresponding to each circle is the base station corresponding to each mapped reference point.
When the base station position information corresponding to each mapped reference point needs to be determined, the base station position information corresponding to each mapped reference point may be determined according to the addition or subtraction of the abscissa of the reference point when the reference point is mapped.
For example, when mapping a reference point, the abscissa of the reference point needs to be subtracted by 2 and the ordinate of the reference point needs to be subtracted by 1, so that when determining the base station position information corresponding to each reference point after mapping, the abscissa of the base station before mapping needs to be subtracted by 2 and the ordinate of the base station before mapping needs to be subtracted by 1. If the position coordinates of the base station before mapping are (3, 2), subtracting 2 from the abscissa of the base station before mapping and subtracting 1 from the ordinate of the base station before mapping are the base station position information corresponding to each reference point after mapping.
According to the user positioning method, the reference points are mapped to the positions of the positioning points, the position information of the mapped reference points is obtained, and then the base station position information corresponding to the mapped reference points is determined according to the position information of the mapped reference points. The position information of the to-be-positioned point can be determined according to the base station position information corresponding to each mapped reference point, and the accuracy of the position information determination of the to-be-positioned point is further ensured.
