The present application provides a positioning correction method, an apparatus, an electronic device, and a computer-readable storage medium, which are intended to solve the above technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
In one embodiment, a positioning correction method is provided, as shown in fig. 1, the method including:
step S101, when a map application program in a terminal is in a working state, determining a first positioning point of the map application program and a first orientation of the first positioning point based on a preset road;
the map application may be an application having a positioning function, such as a map-type application, a navigation-type application, a taxi-type application, and the like.
Specifically, when the map application is in an operating state, a first location point of the map application and a first orientation of the first location point based on the preset road are determined. In practical application, the map application program being in a working state may mean that the map application program is just started and starts to work, or the application program runs in the background, or the application program enters the working state from a non-working state. For example, when the user stands on one side of a road, the terminal is taken out, the map application program is started, the map application program starts to run, and the first positioning point of the map application program and the first orientation of the first positioning point based on the preset road are determined. Of course, the map application may be continuously running. For another example, after the user starts the map application program in the terminal, the terminal automatically locks the screen, at this time, the map application program may be in a non-working state, and when the user unlocks, the map application program may be in a working state again.
Step S102, when the preset positioning point correction condition is detected to be met, determining a second orientation of the terminal based on the road;
in practical application, due to factors such as poor terminal signals and environmental interference, the first positioning point of the map application program in the map and the actual position of the terminal are determined to be different, that is, the position of the first positioning point is wrong, and therefore the positioning point needs to be corrected.
And S103, when the first orientation is inconsistent with the second orientation, correcting the first positioning point to obtain a corrected positioning point.
And after the second orientation is determined, comparing the first orientation with the second orientation, and if the first orientation is not consistent with the second orientation, correcting the first positioning point to obtain a corrected positioning point, and displaying the corrected positioning point in a map application program.
It should be noted that, in the embodiment of the present invention, in the process of positioning and correcting, the terminal may not perform data interaction with the server, and may independently complete positioning and correcting and obtain the corrected positioning point.
In the embodiment of the invention, when a map application program in a terminal is in a working state, a first positioning point of the map application program and a first orientation of the first positioning point based on a preset road are determined; when the preset positioning point correction condition is met, determining a second orientation of the terminal based on the road; and when the first orientation is inconsistent with the second orientation, correcting the first positioning point to obtain a corrected positioning point. Therefore, the first positioning point of the map application program in the map and the road side of the preset road to which the first positioning point belongs are determined, whether the positioning point needs to be corrected is detected, if the positioning point needs to be corrected, the road side of the preset road to which the terminal belongs is determined, and if the positioning point and the road side do not belong to the same side of the preset road, the actual positions of the positioning point and the terminal (user) are respectively located on two sides of the preset road, so that the first positioning point is corrected based on the actual position to obtain the positioning point located on the other side of the road after correction.
In another embodiment, a positioning correction method is provided, as shown in fig. 2, the method including:
step S201, when a map application program in a terminal is in a working state, determining a first positioning point of the map application program and a first orientation of the first positioning point based on a preset road;
the map application may be an application having a positioning function, such as a map-type application, a navigation-type application, a taxi-type application, and the like.
The map application may be installed in a terminal, which may have the following features:
(1) on a hardware architecture, a device has a central processing unit, a memory, an input unit and an output unit, that is, the device is often a microcomputer device having a communication function. In addition, various input modes such as a keyboard, a mouse, a touch screen, a microphone, a camera and the like can be provided, and input can be adjusted as required. Meanwhile, the equipment often has a plurality of output modes, such as a telephone receiver, a display screen and the like, and can be adjusted according to needs;
(2) on a software system, the device must have an operating system, such as Windows Mobile, Symbian, Palm, Android, iOS, and the like. Meanwhile, the operating systems are more and more open, and personalized application programs developed based on the open operating system platforms are infinite, such as a communication book, a schedule, a notebook, a calculator, various games and the like, so that the requirements of personalized users are met to a great extent;
(3) in terms of communication capacity, the device has flexible access mode and high-bandwidth communication performance, and can automatically adjust the selected communication mode according to the selected service and the environment, thereby being convenient for users to use. The device can support GSM (Global System for Mobile Communication), WCDMA (Wideband Code Division Multiple Access), CDMA2000(Code Division Multiple Access), TDSCDMA (Time Division-Synchronous Code Division Multiple Access), Wi-Fi (Wireless-Fidelity), WiMAX (world Interoperability for Microwave Access) and the like, thereby being suitable for various types of networks, and not only supporting voice services, but also supporting various Wireless data services;
(4) in the aspect of function use, the equipment focuses more on humanization, individuation and multi-functionalization. With the development of computer technology, devices enter a human-centered mode from a device-centered mode, and the embedded computing, control technology, artificial intelligence technology, biometric authentication technology and the like are integrated, so that the human-oriented purpose is fully embodied. Due to the development of software technology, the equipment can be adjusted and set according to individual requirements, and is more personalized. Meanwhile, the device integrates a plurality of software and hardware, and the function is more and more powerful.
Specifically, when the map application is in an operating state, a first location point of the map application and a first orientation of the first location point based on the preset road are determined. In practical application, the map application program being in a working state may mean that the map application program is just started and starts to work, or the application program runs in the background, or the application program enters the working state from a non-working state. For example, when the user stands on one side of a road, the terminal is taken out, the map application program is started, the map application program starts to run, and the first positioning point of the map application program and the first orientation of the first positioning point based on the preset road are determined. Of course, the map application may be continuously running. For another example, after the user starts the map application program in the terminal, the terminal automatically locks the screen, at this time, the map application program may be in a non-working state, and when the user unlocks, the map application program may be in a working state again.
In a preferred embodiment of the present invention, determining the first location point of the map application and the first orientation of the first location point based on the preset road includes:
determining a first positioning point of a map application program based on at least one of a preset global positioning system, a network signal and a base station, and determining a first orientation of the first positioning point based on a preset road; the first orientation is a direction in which the anchor point is located on either side of the road.
The first fixed point of the map application program is the coordinate of the map application program in the map. Specifically, the terminal may determine the first location point of the map application through at least one of a global positioning system (e.g., GPS, beidou, etc.), a network signal (e.g., a 4G network signal, a 5G network signal, etc.), and a base station (i.e., a communication base station).
Although the map application performs positioning based on the terminal, the positioning point shown in the map is the coordinate of the map application in the map.
After the first positioning point is determined, a first orientation of the first positioning point based on a preset road can be further determined; wherein, the first orientation is the direction that the setpoint is located any one side in the both sides of road.
Wherein the preset link may be a link closest to the first location point. That is, after the coordinates of the map application on the map are determined, it is further determined on which side of the road the coordinates are located closest to. For example, as shown in FIG. 3, the first location point of the mapping application is determined to be L1, which is located north of the road, so the first orientation of the first location point may be north.
Step S202, when the preset positioning point correction condition is detected to be met, determining a second orientation of the terminal based on the road;
in practical application, due to factors such as poor terminal signals and environmental interference, the first positioning point of the map application program in the map and the actual position of the terminal are determined to be different, that is, the position of the first positioning point is wrong, and therefore the positioning point needs to be corrected.
For example, as shown in fig. 4, it is determined that the first location point of the map application is L1, which is oriented north, and the actual location of the terminal is L2, which is oriented south, then the location of the first location point is wrong, and L1 needs to be revised to L2.
In the embodiment of the invention, when the preset positioning point correction condition is detected to be met, the second orientation of the terminal based on the road can be determined, and the positioning point correction is prepared. The preset positioning point modification condition may be that the positioning accuracy of the positioning point does not exceed a preset positioning accuracy threshold.
In a preferred embodiment of the present invention, the detecting that the preset anchor point modification condition is satisfied includes:
acquiring the positioning precision of a first positioning point;
and when the positioning accuracy does not exceed the positioning accuracy threshold, judging that the preset positioning point modification condition is met.
Here, the positioning Accuracy (Positional Accuracy) is the proximity between the spatial entity position information (usually coordinates) and its real position. Specifically, in the embodiment of the present invention, when the first positioning point is determined, the positioning accuracy of the first positioning point may be determined at the same time, and if the positioning accuracy does not exceed the positioning accuracy threshold, it may be determined that the positioning point correction condition is satisfied, so as to trigger the positioning point correction.
For example, when the first positioning point is determined, and the positioning accuracy of the first positioning point is determined to be 5 meters and less than the positioning accuracy threshold value of 10 meters, it can be determined that the positioning point correction condition is met, and therefore the positioning point correction is triggered.
In a preferred embodiment of the present invention, determining the second orientation of the terminal based on the road includes:
determining a second orientation of the terminal based on a preset road based on a preset magnetic field sensor; the second orientation is a direction in which the terminal is located on either side of the road.
Specifically, the terminal may be preset with a magnetic field sensor capable of indicating the direction of the south, the east, the west and the north by using the earth's magnetic field. For example, in fig. 5, the location point without position indication is shown as (1), after the position is determined by the magnetic field sensor, the corresponding position indication may be added to the location point, and the location point with position indication is shown as (2).
In practical applications, it may be determined by the magnetic field sensor that the orientation of the terminal is based on the road, i.e. on which side of the road the terminal is actually located. Specifically, the terminal may be oriented toward the road, the orientation of the road at the terminal may be determined by the magnetic field sensor, and the orientation of the terminal with respect to the road may then be determined.
For example, as shown in fig. 6, when the terminal is facing the road, it can be determined by the magnetic field sensor that the road is north of the terminal, and then the opposite, terminal is naturally south of the road.
It should be noted that, the terminal may be oriented to the road as shown in fig. 6, or may be in other position relations with the road, such as parallel, back to back, and the like, and in practical application, the terminal may be adjusted according to practical requirements, which is not limited in this embodiment of the present invention.
In a preferred embodiment of the present invention, before determining the second orientation of the terminal based on the road, the method further includes:
displaying a preset confirmation correction interface in a map application program;
and receiving a confirmation correction instruction based on the confirmation correction interface.
Specifically, when the location point correction is triggered, a preset confirmation correction interface may be displayed in a current interface of the map application, as shown in fig. 7, related prompting contents may be displayed in the confirmation correction interface, such as "user-assisted location correction", "currently, you may not be able to accurately locate to the side of a road where you are located, may correct through assisted location", "orient the mobile phone to the road, and slide up for confirmation", and the like, and a confirmed operation prompting content may also be displayed, such as an arrow and a confirmation area, where the user slides up on the terminal according to the prompt of the arrow, and slides up to the confirmation area to initiate a confirmation correction instruction. After receiving the instruction, the map application program can trigger positioning correction, so that the first positioning point is subjected to positioning correction.
It should be noted that, when the terminal is in other position relation with the road, the content of the reminder may be modified adaptively. For example, when the terminal is parallel to the road, the reminding content can be changed into 'parallel the mobile phone to the road and slide up for confirmation'. In practical application, the setting may be performed according to practical requirements, and the embodiment of the present invention is not limited to this.
Step S203, when the first orientation is not consistent with the second orientation, correcting the first positioning point to obtain a corrected positioning point;
and after the second orientation is determined, comparing the first orientation with the second orientation, and if the first orientation is not consistent with the second orientation, correcting the first positioning point to obtain a corrected positioning point, and displaying the corrected positioning point in a map application program.
In a preferred embodiment of the present invention, the modifying the first positioning point to obtain a modified positioning point includes:
acquiring a second positioning point of the terminal based on the second orientation;
and replacing the first positioning point with the second positioning point to obtain the corrected positioning point.
Specifically, the second orientation is determined, i.e. a second location point on the other side of the road is determined. For example, the coordinate closest to the first positioning point on the other side of the road is used as the second positioning point, as shown in fig. 4, L2 is the coordinate closest to L1 on the other side of the road, so L2 is used as the second positioning point. And then replacing the first positioning point with the second positioning point to obtain the corrected positioning point.
Of course, the coordinate closest to the first positioning point in the other side of the road may be used as the second positioning point, and the second positioning point may be determined in other manners, and may be set according to actual requirements in actual applications.
In the actual application test, the positioning result before the positioning point is modified is shown in fig. 8A, and the positioning result after the positioning point is modified is shown in fig. 8B.
In step S204, a second orientation is marked in the road segment of the preset distance corresponding to the corrected location point of the road.
After the modified locating point is obtained, because the locating point icon has a certain size, when the road is narrow, the locating point covers the content of a part of the road, and the situation that the side of the road where the locating point is located cannot be obviously checked occurs. Particularly, in a taxi taking scene, a driver needs to drive the vehicle, and cannot conveniently enlarge the map display positioning point, so that the road side where the positioning point is located can be intensively displayed in a road section with a preset distance in the road on the map, as shown in fig. 9, the direction of an arrow in the road can indicate the second direction of the terminal, and thus the road side of the road where the modified positioning point belongs is determined.
It should be noted that, in the embodiment of the present invention, in the process of positioning and correcting, the terminal may not perform data interaction with the server, and may independently complete positioning and correcting and obtain the corrected positioning point.
In the embodiment of the invention, when a map application program in a terminal is in a working state, a first positioning point of the map application program and a first orientation of the first positioning point based on a preset road are determined; when the preset positioning point correction condition is met, determining a second orientation of the terminal based on the road; and when the first orientation is inconsistent with the second orientation, correcting the first positioning point to obtain a corrected positioning point.
