Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1, fig. 1 is a flowchart of a navigation method provided in an embodiment of the present application, and as shown in fig. 1, the embodiment provides a navigation method applied to an electronic device, including the following steps:
The at least one Positioning System may be one or more of beidou, Global Positioning System (GPS for short), and galileo, and the Positioning System may also adopt inertial navigation. The order between the electronic device acquiring the first positioning information and receiving the second positioning information is not limited.
Both the electronic device and the external device can be mobile terminals, such as mobile phones, tablet computers and the like, and the electronic device and the external device can also be vehicle terminals, which can be understood as vehicle-mounted terminals and the like. For example, the electronic device is a mobile terminal and the external device is a vehicle terminal, or the electronic device is a vehicle terminal and the external device is a mobile terminal. Under the condition that the mobile terminal is in communication with the vehicle end, data can be received and transmitted between the mobile terminal and the vehicle end, for example, the mobile terminal sends data obtained by itself to the vehicle end, or the vehicle end sends data obtained by itself to the mobile terminal.
In the present application, an electronic device is taken as a vehicle terminal, and an external device is taken as a mobile terminal. The vehicle end acquires first positioning information based on at least one positioning system included in the vehicle end, and receives second positioning information sent by the mobile terminal. The first positioning information is positioning information obtained through a positioning system on a vehicle end, and the second positioning information is positioning information obtained through a positioning system on a mobile terminal. The first positioning information may be based on positioning information acquired by a GPS, a beidou positioning system, or a base station. The second Positioning information may be Positioning information obtained based on a Global Positioning System (GPS), a beidou Positioning System, a network, or a base station. Optionally, the second positioning information is more widely sourced than the first positioning information.
And step 102, determining target positioning information according to the first positioning information and the second positioning information.
In this step, which of the first positioning information and the second positioning information is the target positioning information may be determined according to information carried by the first positioning information and the second positioning information. For example, for a vehicle end using a GPS, the positioning accuracy of a positioning chip used at the vehicle end is generally higher than that of a mobile terminal, and when both the vehicle end and the mobile terminal can acquire positioning information, first positioning information acquired at the vehicle end is determined as target positioning information.
For a vehicle end using a GPS, when the vehicle end is in an underground parking lot, the vehicle end may not obtain first positioning information, and the mobile terminal may obtain second positioning information based on the base station, and at this time, the second positioning information is determined as target positioning information according to the second positioning information obtained by the mobile terminal.
And 103, navigating according to the target positioning information.
And after the target positioning information is determined, navigation is performed according to the target positioning information, so that the navigation precision is improved.
In this embodiment, based on at least one positioning system, first positioning information is acquired, and second positioning information from a communication-connected external device is received; determining target positioning information according to the first positioning information and the second positioning information; and navigating according to the target positioning information. The first positioning information and the second positioning information are comprehensively considered when the target positioning information is determined, so that the positioning accuracy can be improved. Meanwhile, the use scene of positioning through at least one positioning system is expanded, and the scene adaptability of the electronic equipment for positioning through the at least one positioning system is enhanced.
In one embodiment of the present application, the first positioning information includes a first timestamp, and the second positioning information includes a second timestamp;
and if one of the first timestamp and the second timestamp is not within a first preset time period, determining the positioning information to which the timestamp in the first preset time period belongs in the first timestamp and the second timestamp as the target positioning information.
In this embodiment, the first timestamp may be understood as a time when the first positioning information is acquired, and the second timestamp may be understood as a time when the second positioning information is acquired. The first preset time period may be set according to actual conditions, for example, a time period of pushing forward for 2 seconds is a first preset time period, with a time period of acquiring the first positioning information and the second positioning information as an end point. If the first timestamp is 58 minutes in the morning, the second timestamp is 9 minutes in the morning and 2 minutes in the morning, and the time for acquiring the first positioning information and the second positioning information is 9 minutes in the morning and 3 minutes in the morning, the first preset time period is in the range of 9 minutes in the morning and 1 minutes to 9 minutes in the morning and 3 minutes in the morning, only the second timestamp falling in the first preset time period is determined, and in this case, the second positioning information is determined as target positioning information, that is, the positioning information to which the timestamp falling in the first preset time period belongs is determined as the target positioning information.
Alternatively, the first time stamp may be a time measured with a time when the first positioning information is generated as a start time, and the second time stamp may be a time measured with a time when the second positioning information is generated as a start time. The first preset time can be set according to actual conditions, for example, 2 seconds. If the first timestamp is 1 second and the second timestamp is 3 seconds when the electronic device acquires the first positioning information, only the first timestamp falling within a first preset time period is determined, and in this case, the first positioning information is determined as target positioning information, that is, the positioning information to which the timestamp falling within the first preset time period belongs is determined as the target positioning information.
In this embodiment, the first timestamp of the first positioning information and the second timestamp of the second positioning information are compared, and the positioning information to which the timestamp falling within the first preset time period belongs is determined as the target positioning information.
In an embodiment of the present application, the step 102 of determining the target positioning information according to the first positioning information and the second positioning information includes:
and if the first time stamp and the second time stamp are both within the first preset time period, determining the positioning information with high positioning precision in the first positioning information and the second positioning information as the target positioning information.
In this step, if the first timestamp and the second timestamp are both within the first preset time period, it is indicated that the first positioning information and the second positioning information both belong to newly acquired positioning information, and at this time, the positioning accuracy of the first positioning information and the positioning accuracy of the second positioning information are compared, and the positioning information with high positioning accuracy is determined as target positioning information. The positioning accuracy is understood to be the degree to which the positioning can be accurate, e.g. 5 meters, 3 meters, etc., of which 3 meters is higher than 5 meters. The positioning accuracy is included in the positioning information.
In this embodiment, if the first time stamp and the second time stamp are both within the first preset time period, the positioning information with high positioning accuracy in the first positioning information and the second positioning information is determined as the target positioning information, and the positioning accuracy of the target positioning information can be ensured as much as possible on the premise of ensuring the positioning information newly obtained by the target positioning information.
In an embodiment of the present application, the step 101 of acquiring first positioning information based on at least one positioning system and receiving second positioning information from a communicatively connected external device includes:
and acquiring first positioning information based on at least one positioning system every a second preset time period, and receiving second positioning information from external equipment in communication connection, wherein the second preset time period is less than the first preset time period.
The second preset time can be flexibly set according to actual conditions, for example, 1 second, and is not limited herein. In this embodiment, a 1 second cycle timer may be started to periodically obtain the second positioning information newly obtained by the mobile terminal and the first positioning information newly obtained by the vehicle end, and if the timestamps of the first positioning information and the second positioning information are within a first preset time period, the positioning accuracy of the first positioning information and the second positioning information is compared, and then the positioning information with higher positioning accuracy is used for subsequent positioning.
In this embodiment, the first positioning information is acquired based on at least one positioning system every second preset time period, and the second positioning information from the external device in communication connection is received, so that the electronic device can acquire the latest first positioning information and the latest second positioning information, and the positioning accuracy can be improved.
And the mobile terminal is provided with arbitration service for arbitrating the received first positioning information and the second positioning information and determining target positioning information. Similarly, the vehicle end may also set an arbitration service for arbitrating the received first positioning information and the second positioning information to determine the target positioning information. As shown in fig. 2, fig. 2 is a schematic flow chart of the navigation method provided by the present application, and in fig. 2, the first preset time period is 2 seconds, and the second preset time period is 1 second.
The navigation method can fully utilize the advantages of different positioning of the mobile terminal and the vehicle end, for example, the positioning information of the vehicle end has higher precision than that of the mobile terminal, the mobile terminal adopts a satellite positioning system at the vehicle end, and the mobile terminal can obtain the positioning information based on the base station under the condition that the positioning information cannot be received by the underground layer. The navigation method can avoid respective short boards, and when the first positioning information acquired by the vehicle end is not the latest positioning information (namely the timestamp of the first positioning information is not in a first preset time period), the second positioning information acquired by the mobile terminal is adopted for positioning; when the respective timestamps of the first positioning information acquired at the vehicle end and the second positioning information acquired by the mobile terminal are within a first preset time period, the positioning information with higher positioning accuracy is adopted for positioning, and the positioning accuracy is improved as much as possible. The navigation method in the application can be simultaneously suitable for mobile terminal navigation and vehicle end navigation, and can improve the positioning accuracy and user experience of the mobile terminal navigation and the vehicle end navigation.
