Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
As known from the background art, the current method for solving the above technical problems is mainly implemented by a hardware method, that is: the existing positioning system is directly improved by adding positioning system hardware, so that the support for improving the dimensionality is realized. For example: the number of positioning devices is increased, and the devices meeting the requirement of high-dimensional positioning are replaced.
However, the inventor of the present application has found that, although the above method is direct and effective, the following problems may occur:
firstly, the cost input aspect: since the number of hardware devices is increased or higher configuration hardware devices are replaced, the capital investment cost for adding hardware and even the whole software and hardware system is greatly increased.
Second, system implementation aspects: since the problem is solved from the hardware aspect, there is a workload in construction, for example: on-site measurement, installation and erection of positioning equipment, laying of pipelines and other time-consuming and labor-consuming works.
Third, interrupt used by the positioning system: since the old and new systems need to be merged and docked from the hardware layer, the original positioning system needs to be shut down and temporarily unable to provide service during merging and docking, so that the positioning service is interrupted during docking, which is unacceptable for positioning systems with high reliability requirements and availability.
Based on the above technical problem, the present inventors propose the following technical solution to solve or improve the above problem. It should be noted that the above prior art solutions have shortcomings, which are the results of practical and careful study by the inventor, and therefore, the discovery process of the above problems and the solutions proposed by the following embodiments of the present application for the above problems should be the contribution of the inventor to the present application in the course of the present invention.
Please refer to fig. 1, which is a schematic view of an application scenario of the positioning dimension lifting method according to the embodiment of the present application. The application scenario may comprise a plurality of location servers 300 and a location server 100 communicatively connected to the plurality of location servers 300.
In this embodiment, the positioning server 300 may be configured to obtain positioning information of each positioning point, for example, a positioning coordinate point, and send the positioning coordinate point to the positioning server 100. The positioning server 100 is configured to perform information processing on the positioning information of each positioning point to obtain actual position information of each positioning point.
The positioning dimension improvement method shown in fig. 2 is described in detail below with reference to the application scenario shown in fig. 1, where the positioning dimension improvement method is executed by the positioning server 100 shown in fig. 1, or in some possible implementations, the positioning dimension improvement method may also be executed by the positioning base station 300 shown in fig. 1, and the positioning server 100 is executed as an example, which is described in detail below. It can be understood that the positioning dimension lifting method provided in this embodiment is not limited to the specific sequence shown in fig. 2 and described below, and the detailed steps of the positioning dimension lifting method are as follows:
step S110, a two-dimensional positioning coordinate system is established in the current positioning area, and at least two one-dimensional positioning coordinate systems in the current positioning area are added into the two-dimensional positioning coordinate system.
In a possible implementation manner, when the current positioning area includes at least two one-dimensional positioning coordinate systems, the origin of the two-dimensional positioning coordinate system to be established for any position seat in the current positioning area may be selected according to actual requirements, and the X-axis direction and the Y-axis direction are determined, so as to establish the two-dimensional positioning coordinate system in the current positioning area, and then the at least two one-dimensional positioning coordinate systems in the current positioning area are added to the two-dimensional positioning coordinate system.
For example, in the application scenario shown in fig. 3, it is assumed that the current positioning scenario includes two one-dimensional positioning coordinate systems with non-parallel positioning coordinates, where the two one-dimensional positioning coordinate systems are a 1# positioning coordinate system and a 2# one-dimensional coordinate system, respectively, and at this time, an origin (0, 0) is selected according to actual requirements, and an X axis and a Y axis are determined to determine an XY coordinate system shown in fig. 3, and then the 1# one-dimensional coordinate system and the 2# one-dimensional coordinate system are added to the two-dimensional positioning coordinate system.
In a possible implementation manner, this embodiment may further determine coordinates of each coordinate point in each one-dimensional positioning coordinate system in the two-dimensional positioning coordinate system according to a position of each one-dimensional positioning coordinate system in the two-dimensional positioning coordinate system, and then configure a coordinate transformation rule between each one-dimensional positioning coordinate system and the two-dimensional positioning coordinate system according to coordinates of each coordinate point in each one-dimensional positioning coordinate system and coordinates of each coordinate point in the two-dimensional positioning coordinate system.
For example, in the application scenario shown in fig. 3, the coordinates of each coordinate point in the # 1 one-dimensional coordinate system and the # 2 one-dimensional coordinate system in the two-dimensional positioning coordinate system may be determined according to the positions of the # 1 positioning coordinate system and the # 2 one-dimensional coordinate system in the two-dimensional positioning coordinate system, and then the coordinate transformation rule between each one-dimensional positioning coordinate system and the two-dimensional positioning coordinate system may be configured according to the coordinates of each coordinate point in the # 1 one-dimensional coordinate system and the # 2 one-dimensional coordinate system and the coordinates of each coordinate point in the two-dimensional positioning coordinate system.
It should be noted that, if only one-dimensional positioning scene exists in the current positioning area, so that only one-dimensional positioning coordinate system exists, another one-dimensional positioning coordinate system that is not parallel to the one-dimensional positioning coordinate system in the current positioning area may be added.
Step S120, aiming at each one-dimensional positioning coordinate system, obtaining a coordinate point and a one-dimensional coordinate of the current positioning point in the one-dimensional positioning coordinate system, and calculating a two-dimensional coordinate of the coordinate point in the two-dimensional positioning coordinate system according to the one-dimensional coordinate and a coordinate conversion rule between the one-dimensional positioning coordinate system and the two-dimensional positioning coordinate system.
In this embodiment, for each one-dimensional positioning coordinate system, such as the 1# one-dimensional coordinate system and the 2# one-dimensional coordinate system in fig. 3, it is assumed that the positioning point of the current positioning point on the 1# one-dimensional coordinate system is P1 points with one-dimensional coordinates of X11, and the positioning point on the 2# one-dimensional positioning coordinate system is P2 points with one-dimensional coordinates of X12.
In one possible implementation, the offset of the one-dimensional coordinate of the coordinate point in the two-dimensional positioning coordinate system may be calculated according to the one-dimensional coordinate and a coordinate transformation rule between the one-dimensional positioning coordinate system and the two-dimensional positioning coordinate system.
Then, a target first coordinate of the one-dimensional coordinate in the two-dimensional positioning coordinate system and a target second coordinate corresponding to the target first coordinate are calculated according to the offset of the one-dimensional coordinate of the coordinate point in the two-dimensional positioning coordinate system.
And obtaining a two-dimensional coordinate of the coordinate point in the two-dimensional positioning coordinate system according to the target first coordinate and the target second coordinate.
For example, in the application scenario shown in fig. 3, two-dimensional coordinates of the positioning points in the 1# one-dimensional coordinate system and the 2# one-dimensional coordinate system may be calculated, and according to the coordinate transformation rule between each one-dimensional positioning coordinate system and the two-dimensional positioning coordinate system determined above, the offset amount of the P1 point in the two-dimensional coordinate system and the offset amount of the P2 point in the two-dimensional positioning coordinate system are calculated, and then, according to the offset amount of the P1 point in the two-dimensional coordinate system and the offset amount of the P2 point in the two-dimensional positioning coordinate system, the two-dimensional positioning coordinates of the P1 point in the two-dimensional coordinate system are calculated as (X21, Y21), and the two-dimensional positioning coordinates of the P2 point in the two-dimensional coordinate system are calculated.
Step S130, calculating a two-dimensional coordinate of the current positioning point in the two-dimensional positioning coordinate system according to a two-dimensional coordinate of a coordinate point in each one-dimensional positioning coordinate system in the two-dimensional positioning coordinate system.
In one possible implementation, for each one-dimensional positioning coordinate system, a perpendicular line equation passing through the coordinate point and perpendicular to the one-dimensional positioning coordinate system may be calculated according to an axis slope of the one-dimensional positioning coordinate system in the two-dimensional positioning coordinate system and a two-dimensional coordinate of the coordinate point in the two-dimensional positioning coordinate system, so as to obtain a perpendicular line equation perpendicular to each one-dimensional positioning coordinate system.
For example, in the application scenario shown in fig. 3, in the 1# one-dimensional coordinate system, a perpendicular equation of the P1 point perpendicular to the perpendicular line AB of the 1# one-dimensional coordinate system may be calculated according to the two-dimensional coordinates (X21, Y21) of the P1 point and the axis slope K1 of the 1# one-dimensional coordinate system, and similarly, in the 2# one-dimensional coordinate system, a perpendicular equation of the P2 point perpendicular to the perpendicular line CD of the 2# one-dimensional coordinate system may be calculated according to the two-dimensional coordinates (X22, Y22) of the P2 point and the axis slope K1 of the 2# one-dimensional coordinate system.
Then, an intersection point between each vertical line equation is calculated, and a two-dimensional coordinate of the current positioning point in the two-dimensional positioning coordinate system is determined according to the intersection point between each vertical line equation.
Optionally, it may be determined whether the intersection points between the vertical line equations coincide, and if the intersection points between the vertical line equations coincide, the intersection points between the vertical line equations are used as the two-dimensional coordinates of the current positioning point in the two-dimensional positioning coordinate system.
For example, in the application scenario shown in fig. 3, according to the calculated AB perpendicular equation and CD perpendicular equation, an intersection point P3 between the AB perpendicular equation and the CD perpendicular equation may be calculated, the two-dimensional coordinate of the intersection point P3 is (X23, Y23), and the coordinate (X23, Y23) is the two-dimensional coordinate of the current positioning point in the two-dimensional positioning coordinate system, that is, the coordinate lifted from the one-dimensional positioning dimension to the two-dimensional positioning dimension.
For another example, when there are more than two non-parallel one-dimensional positioning scenes in the positioning scene, due to the influence of the field environment, interference on wireless signal transmission, jitter of the wireless signal, and the like, the vertical line equations calculated under the multiple one-dimensional positioning coordinate systems cannot be completely intersected at one point, as shown in fig. 4.
Under the above condition, if the intersection points between the vertical line equations do not coincide, any one of the intersection points between the vertical line equations is taken as the two-dimensional coordinate of the current positioning point in the two-dimensional positioning coordinate system. For example, the point P1, the point P2 and the point P3 shown in fig. 4 may be taken as the two-dimensional coordinates of the current positioning point in the two-dimensional positioning coordinate system
Or, a minimum circumscribed circle passing through an intersection point between the vertical line equations may be calculated, and a center coordinate of the minimum circumscribed circle may be used as a two-dimensional coordinate of the current positioning point in the two-dimensional positioning coordinate system. For example, a minimum circumscribed circle passing through the intersection points P1, P2, and P3 between the respective vertical line equations may be calculated, and the center coordinate O of the minimum circumscribed circle may be taken as the two-dimensional coordinate of the current positioning point in the two-dimensional positioning coordinate system.
Therefore, based on the above design, the positioning dimension lifting method provided in this embodiment can determine a two-dimensional positioning coordinate system by using at least two existing one-dimensional positioning coordinate systems in the positioning principle, and in a service scene of specifically lifting the positioning dimension, can determine the two-dimensional positioning coordinate of the positioning point according to geometric calculation by using the one-dimensional positioning data of at least two non-parallel one-dimensional positioning coordinate systems. From this, need not to invest into too much hardware equipment and engineering construction volume and can further promote the location dimension on the basis of original location dimension in order to satisfy the later stage demand to save a large amount of funds, manpower, time cost. In addition, the positioning dimension can be improved in the process of working simultaneously with the original one-dimensional positioning system, the work of the existing one-dimensional positioning system is not required to be interrupted, and the positioning reliability is improved.
Further, referring to fig. 5, corresponding to the above positioning dimension lifting method, an embodiment of the present application further provides a positioning dimension lifting device 200, and the functions implemented by the positioning dimension lifting device 200 may correspond to the steps executed by the above method. The positioning dimension promoting device 200 may be understood as the positioning server 100, or may be understood as a component that is independent from the positioning server 100 and implements each functional module of the embodiment under the control of the positioning server 100, as shown in fig. 5, the functions of each functional module that the positioning dimension promoting device 200 may include are explained in detail.
