Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and more particularly, to a positioning method and device, an electronic device, and a storage medium. BACKGROUND

[0002] With the continuous development of positioning technology in wireless communication, various navigation software for navigation positioning emerge in endlessly. The convenient navigation function of the navigation software brings great convenience to people's life and travel. The current navigation software can only position the approximate position of the positioning target when navigating. For example, the positioning target is positioned near a building or near the gate of a park. In the ordinary urban environment, the mobile phone will only give a rough positioning point of the positioning target when positioning for a ride. In the absence of landmark buildings, the user cannot be informed of which side of the road the positioning target is on. In some road sections with roadblocks, it is difficult for a taxi to find a ride user, or it needs to bypass a long roadblock to reach the user, and the specific position of the user cannot be determined in advance.

[0067] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0068] To facilitate understanding of any embodiment of this disclosure, a positioning method in a ride-hailing scenario will be described first.

[0069] Please see Figure 1 The user is on side B of the road, and their location is the destination D. The taxi is at the starting point C. The taxi needs to travel from starting point C to destination D to pick up the user.

[0070] In one embodiment, the taxi uses a navigation application to determine a route from the starting point C to the destination D. Here, the navigation application is running on both the user's first terminal and the taxi driver's second terminal.

[0071] In one embodiment, both the first terminal and / or the second terminal can be located based on the navigation application and positioning satellites.

[0072] In one embodiment, the navigation application uses a second terminal to locate the first terminal located at the destination D, and determines the navigation route based on the location information of the destination D. Here, the navigation route is a navigation route planned based on the starting point C and the destination D, and the taxi moves along the navigation route to the user.

[0073] In one embodiment, the location information obtained by the second terminal in locating the first terminal is approximate location information of the first terminal. For example, the first terminal may be located anywhere in region E. Therefore, the navigation application cannot determine the user's exact location based on this approximate location information.

[0074] In one embodiment, the navigation application is unsure whether the user is located on side A or side B of the road, and therefore cannot plan a navigation route based on the actual location of the first terminal. This results in a non-optimal navigation route, which may cause the driver to take a detour, leading to a poor experience for both the driver and the user.

[0075] like Figure 2 As shown, this embodiment provides a positioning method applied to a terminal, wherein the method includes:

[0076] Step 21: Obtain the location scene information of the terminal in the current location scene;

[0077] Step 22: Based on the positioning scenario information, determine the target positioning mode that meets the positioning requirements of the current positioning scenario from the preset positioning modes with different positioning performance;

[0078] Step 23: Obtain navigation and positioning information based on the target positioning mode.

[0079] Here, the terminal may be, but is not limited to, a mobile phone, a wearable device, a vehicle terminal, a roadside unit (RSU), an industrial sensing device, and / or a medical device.

[0080] Here, the current location scenario can be the location scenario corresponding to the current location of the terminal.

[0081] In one embodiment, in response to the movement of the terminal, the terminal may be in different location scenarios at different times.

[0082] In one embodiment, the terminal locates a position of a positioning target by using a navigation application and a positioning satellite, and obtains position information of the positioning target. The terminal plans a navigation route based on the position information of the positioning target and position information of a location where the terminal is located, and obtains the navigation route. Here, the terminal moves to a location where the positioning target is located on the navigation route. That is, the terminal moves from a start location of the navigation route to an end location of the navigation route.

[0083] In one embodiment, when the terminal is located on different road segments on the navigation route, the terminal is located in different positioning scenarios.

[0084] In one embodiment, if the terminal is located on road segments at two ends of the navigation route, the positioning scenario is a first positioning scenario; if the terminal is located on a middle road segment on the navigation route, the positioning scenario is a second positioning scenario.

[0085] In one embodiment, the road segments at two ends can be road segments on the navigation route that are less than a distance threshold from the start location and / or road segments on the navigation route that are less than a distance threshold from the end location.

[0086] In one embodiment, the middle road segment can be a road segment on the navigation route that is greater than a distance threshold from both the end location and the start location.

[0087] In one embodiment, the navigation route can be a route determined by the navigation application based on a start location and an end location of the terminal input by a user.

[0088] In one embodiment, in the first positioning scenario corresponding to the road segment a, the terminal needs to use a high-performance positioning method to locate the terminal. In the second positioning scenario corresponding to the road segment b, the terminal can use a low-performance positioning method to locate the terminal.

[0089] In one embodiment, the high-performance positioning method requires more positioning resources than the low-performance positioning method. Here, the positioning resources include computing resources and processor resources, etc.

[0090] In one embodiment, the positioning performance of the terminal can be determined according to positioning accuracy and / or positioning time.

[0091] In one embodiment, the high-performance positioning method can be a positioning method with positioning accuracy greater than an accuracy threshold and positioning time less than a time threshold.

[0092] In one embodiment, the low-performance positioning method can be a positioning method with positioning accuracy less than the accuracy threshold and positioning time greater than the positioning threshold.

[0093] In one embodiment, the positioning accuracy of the terminal positioning in the first positioning scenario needs to be greater than the positioning accuracy of the terminal positioning in the second positioning scenario.

[0094] In one embodiment, the positioning time of the terminal positioning in the first positioning scenario needs to be less than the positioning time of the terminal in the second positioning scenario.

[0095] In one embodiment, the high-performance positioning method can be a positioning method based on carrier phase difference technology (RTK, Real Time Kinematic). Here, the positioning accuracy of the positioning method based on carrier phase difference technology (RTK) is greater than the accuracy threshold and the positioning time is less than the time threshold.

[0096] In one embodiment, when the buildings around the location of the terminal are different, the terminal is in different positioning scenarios.

[0097] In one embodiment, when there is a target building in the area range whose distance from the location of the terminal is less than a distance threshold, the terminal is in a first positioning scenario.

[0098] In one embodiment, the target building categories can be pre-set. The terminal can determine whether the building is a target building based on the obtained building information.

[0099] In one embodiment, the target building includes at least one of the following: hospital buildings, school buildings, and residential area buildings, etc.

[0100] In one embodiment, when there is no target building in the area range whose distance from the location of the terminal is less than a distance threshold, the terminal is in a second application scenario.

[0101] In one embodiment, when there is a building with a height less than a height threshold in the area range whose distance from the location of the terminal is less than a distance threshold, the terminal is in a first positioning scenario.

[0102] In one embodiment, when there is no building with a height less than a height threshold in the area range whose distance from the location of the terminal is less than a distance threshold, the terminal is in a second application scenario.

[0103] In one embodiment, the positioning scenario information is information in the positioning scenario corresponding to the location of the terminal.

[0104] In one embodiment, the positioning scene information comprises information of at least one of the following: road segment information of a road segment where the terminal is located, information of a target building, and building shape information. Here, the road segment information of the road segment where the terminal is located can be road segment information of a navigation route, for example, the terminal is located at a middle road segment of the navigation route, or the terminal is located at a road segment at two ends of the navigation route. Here, the information of the target building can be category information of the target building. Here, the building shape information can be height information of the building, width information of the building, and / or length information of the building.

[0105] In one embodiment, the terminal can periodically acquire positioning scene information in a current positioning scene of the terminal.

[0106] In one embodiment, when the moving speed of the terminal is greater than a speed threshold, a period corresponding to acquisition of the positioning scene information in the current positioning scene of the terminal can be less than a period threshold; when the moving speed of the terminal is less than the speed threshold, the period corresponding to acquisition of the positioning scene information in the current positioning scene of the terminal can be greater than the period threshold. In this way, the terminal can adjust the period in real time according to the moving condition of the terminal, and update the navigation positioning information in time.

[0107] In one embodiment, the terminal is configured with at least two preset positioning modes with different performances.

[0108] In one embodiment, a user can operate the terminal to add different preset positioning modes according to a positioning scene.

[0109] In one embodiment, the terminal can select at least two preset positioning modes from a plurality of optional preset positioning modes for positioning of the terminal.

[0110] In one embodiment, the performance of the preset positioning mode comprises at least one of the following: positioning accuracy, positioning time, and anti-occlusion capability.

[0111] In one embodiment, the anti-occlusion capability is a capability of a positioning method adopted by a preset positioning mode to resist building occlusion of a positioning signal.

[0112] In one embodiment, the anti-occlusion capability of a positioning method that adopts a long-wave signal for positioning is greater than the anti-occlusion capability of a positioning method that adopts a short-wave signal for positioning.

[0113] In one embodiment, the preset positioning mode at least comprises:

[0114] a first positioning mode and a second positioning mode;

[0115] The positioning accuracy of the first positioning mode is higher than the positioning accuracy of the second positioning mode, or the anti-occlusion capability of the first positioning mode is higher than the anti-occlusion capability of the second positioning mode.

[0116] In an embodiment, a relationship between the preset positioning mode and the performance parameter corresponding to the preset positioning mode is preset.

[0117] In an embodiment, the terminal can determine an application scenario in which the terminal is located according to road segment information, target building information, and / or building shape information of a location where the terminal is located.

[0118] In an embodiment, the terminal needs to use different positioning modes for positioning in different application scenarios.

[0119] In an embodiment, the positioning requirement in the positioning scenario can be a requirement for a performance parameter in the positioning scenario. For example, in a first positioning scenario, there is a requirement to use a high-performance positioning method for positioning; in a second positioning scenario, there is a requirement to use a low-performance positioning method for positioning.

[0120] In an embodiment, the high-performance positioning method occupies a larger number of resources than the low-performance positioning method. The resources can be at least one of the following: central processing unit resources, storage resources, computing power resources, and / or data resources.

[0121] In an embodiment, after the terminal obtains the positioning scenario information, the terminal determines a positioning scenario in which the terminal is currently located, and selects a target positioning mode from the preset positioning modes according to the performance parameter requirement in the currently located positioning scenario, and performs positioning of the terminal based on the target positioning mode.

[0122] In an embodiment, the target positioning mode can be used to obtain navigation positioning information.

[0123] In an embodiment, the navigation positioning information can be position information of a target device obtained by the terminal based on a navigation application and a positioning satellite. For example, the position information can be road side information that the target device is located on one side of a road. Alternatively, the position information can be road side information that the target device is located on one side of a target building.

[0124] In one embodiment, a taxi driver uses a navigation application and positioning satellites in an in-vehicle terminal to locate the customer's mobile phone. The in-vehicle terminal acquires positioning scenario information for the current positioning scenario; based on the positioning scenario information, it determines a target positioning mode from preset positioning modes with different positioning performance that meets the positioning requirements of the current positioning scenario; and based on the target positioning mode, it obtains roadside information of the mobile phone. Here, roadside information refers to the location information of the customer's mobile phone on side A of the road. The road is divided into side A and side B.

[0125] In one embodiment, the second positioning mode is the native positioning mode; the first positioning mode is a fusion mode that combines the native positioning mode and the auxiliary positioning mode for positioning.

[0126] In one embodiment, the native positioning mode can be a mode based on the Global Positioning System (GPS) or a mode based on a network.

[0127] In one embodiment, the native positioning mode is a positioning mode in which the underlying positioning program is not modified. Here, "unmodified underlying program" includes that the content of the underlying program is not added to, deleted from, and / or changed.

[0128] In one embodiment, the assisted positioning mode is a carrier phase differential positioning mode based on real-time dynamic (RTK).

[0129] In one embodiment, the first positioning mode may be a combination of at least one of the following modes: a GPS-based positioning mode, a network-based positioning mode, and a real-time kinematic (RTK) carrier phase differential positioning mode.

[0130] In this embodiment of the disclosure, since the target positioning mode is determined from preset positioning modes with different positioning performance based on the positioning scene information of the terminal in the current positioning scene, and the positioning performance of the target positioning mode can meet the needs of the current positioning scene, the terminal can perform positioning based on the target positioning mode adapted to the current positioning scene. Compared with the method of always using a single performance positioning mode for terminal positioning, it can better adapt to the current positioning scene, meet the positioning needs in the current positioning scene, and bring a better user experience.

[0131] like Figure 3 As shown, this embodiment provides a positioning method, wherein step 22, determining a target positioning mode that meets the positioning requirements of the current positioning scenario from preset positioning modes with different positioning performance based on the positioning scenario information, includes:

[0132] Step 31: In response to determining the current positioning scene as an occlusion scene based on the positioning scene information, determine the first positioning mode as the target positioning mode; wherein, the occlusion scene is a positioning scene with an obstruction within a preset range of the location of the terminal.

[0133] In one embodiment, in an obstructed scenario, the signal used for terminal positioning is blocked by an obstruction. That is, the signal used for terminal positioning is interfered with by the obstruction.

[0134] In one embodiment, when the terminal is located in an obstructed scene, a positioning mode based on long-wavelength signals can be used for positioning.

[0135] In one embodiment, the positioning mode using long-wavelength signals has a greater resistance to obstruction than the positioning mode using short-wavelength signals. Here, the resistance to obstruction refers to the ability of the positioning signal corresponding to the positioning method used in the preset positioning mode to resist obstruction by buildings. In one embodiment, the obstruction can be at least one of buildings, mountains, and / or trees. Here, buildings can include at least one of the following: hospital buildings, school buildings, and residential buildings, etc.

[0136] In one embodiment, the location scene information may be the shape information of an obstruction within a preset range from the location of the terminal. Here, the shape information includes the height, width, and / or length of the obstruction.

[0137] In one embodiment, if at least one of the height, width, and / or length of the obstruction is greater than a set threshold, the signal strength for the terminal to locate will be reduced due to the obstruction.

[0138] In one embodiment, the preset positioning mode includes a first positioning mode and a second positioning mode, wherein the first positioning mode has a higher resistance to occlusion during positioning than the second positioning mode. The target positioning mode is the first positioning mode. Thus, in occlusion scenarios, the terminal can obtain more accurate positioning results.

[0139] In one embodiment, the positioning accuracy of the first positioning mode is higher than that of the second positioning mode.

[0140] In one embodiment, the occlusion scenario can be a positioning scenario where there is a target occlusion within a distance of less than a distance threshold from the location of the terminal.

[0141] In one embodiment, the types of target buildings can be preset. The terminal can determine whether a building is a target building based on the acquired building information.

[0142] like Figure 4 As shown, this embodiment provides a positioning method, wherein step 22, determining a target positioning mode that meets the positioning requirements of the current positioning scenario from preset positioning modes with different positioning performance based on the positioning scenario information, includes:

[0143] Step 41: In response to determining the current positioning scene as an open scene based on the positioning scene information, determine the second positioning mode as the target positioning mode; wherein, the open scene is a positioning scene in which there are no obstructions within a preset range of the location of the terminal.

[0144] In one embodiment, in an open environment, the signal used for terminal positioning is not blocked by any obstructions. That is, the signal used for terminal positioning is not interfered with by obstructions.

[0145] In one embodiment, when the terminal is located in an open scene, a positioning mode based on shortwave signals can be used for positioning.

[0146] In one embodiment, the positioning mode using long-wavelength signals has a greater resistance to obstruction than the positioning mode using short-wavelength signals. Here, the resistance to obstruction refers to the ability of the positioning signal corresponding to the positioning method used in the preset positioning mode to resist obstruction by buildings.

[0147] In one embodiment, the obstruction may be at least one of buildings, mountains, and / or trees. Here, the buildings may include at least one of the following: hospital buildings, school buildings, and residential buildings, etc.

[0148] In one embodiment, the positioning scene information may be the shape information of an object within a preset range from the location of the terminal. Here, the shape information includes the height, width, and / or length of the obstruction.

[0149] In one embodiment, in response to the height, width, and length of the object being less than a set threshold, the signal strength for positioning by the terminal will not decrease due to obstruction by the obstruction.

[0150] In one embodiment, the preset positioning mode includes a first positioning mode and a second positioning mode, wherein the first positioning mode has a higher resistance to occlusion than the second positioning mode. The target positioning mode is the second positioning mode. Thus, in occluded scenarios, the terminal can obtain more accurate positioning results.

[0151] In one embodiment, the positioning accuracy of the first positioning mode is higher than the positioning accuracy of the second positioning mode.

[0152] In one embodiment, the positioning time of the first positioning mode is less than the positioning time of the second positioning mode.

[0153] In one embodiment, the open scene can be a positioning scene without obstructions within a range of less than a distance threshold from a position where the terminal is located.

[0154] As shown in Figure 5 In this embodiment, a positioning method is provided, wherein step 22, the target positioning mode that meets the positioning requirement in the current positioning scene is determined from the preset positioning modes with different positioning performances according to the positioning scene information, comprising:

[0155] Step 51, in response to determining that the current positioning scene is a scene where the terminal moves on a first road segment according to the positioning scene information, determining that the second positioning mode is the target positioning mode; wherein the first road segment is a middle road segment on a navigation road segment where the terminal is located.

[0156] In one embodiment, in the scene where the terminal moves on the first road segment, there is no need for accurate positioning, and there is no need for accurate positioning. For example, when the terminal moves on the first road segment, there is no need to acquire and / or display the roadside information on one side of the road where the target device is located.

[0157] In one embodiment, the first road segment can be a road segment with a distance greater than a distance threshold from the end position and the start position. The end position is the end position on the navigation route where the terminal is located; the start position is the start position on the navigation route where the terminal is located.

[0158] In one embodiment, the positioning scene information can be coordinate position information of the first road segment where the terminal is located. The coordinate position information can be relative coordinate information of the position where the terminal is located from the start position and / or the end position.

[0159] In one embodiment, the preset positioning mode includes a first positioning mode and a second positioning mode, wherein the anti-obstruction capability of the first positioning mode during positioning is higher than the anti-obstruction capability of the second positioning mode during positioning. The target positioning mode is the second positioning mode. In this way, in the scene where the terminal moves on the first road segment, according to the positioning requirement, there is no need to use the accurate positioning mode for positioning, and the resources used for positioning are saved.
