The embodiments of the present application will be described from the perspective of an area location device, which may be specifically integrated in a server.
As shown in fig. 5, a specific process of the area positioning method may be as follows:
201. the server obtains a historical positioning request initiated by a sample terminal in a preset geographic area, and obtains a historical positioning request set, wherein the historical positioning request comprises positioning information of the sample terminal, and the preset geographic area comprises a plurality of blocks.
For example, in an offline state, the server may obtain historical positioning requests initiated by a plurality of sample terminals in an outdoor 50-meter geographic area of some buildings (such as a mall, a hospital, an office building, and the like), where the historical positioning requests are positioning requests within a current previous segment, and filter the historical positioning requests to obtain a historical positioning request set, so as to serve positioning of subsequent terminals.
The preset geographic area can be a certain geographic area outside a mall building, as shown in fig. 6, the slower the movement speed of a person is, the slower the movement speed of the person is, the slower the initiation speed of a historical positioning request can be reflected, the farther the person is from the mall building, because of a positioning request in a mobile vehicle, the speed of a part of requests is faster, and the degree of distinction between the requests and the requests in the mall building is higher, according to the initiation speed of the historical positioning request, the certain geographic area outside the mall building can be divided, the area size of the preset geographic area can be obtained as required, and then the area can be divided into a plurality of blocks.
202. The server establishes a mapping relation between the positioning information and the block to obtain a mapping relation set.
For example, a mapping relationship is established between the acquired positioning information and a plurality of blocks, after the mapping relationship is established, the positioning information in the blocks is fused, and the plurality of blocks are filtered, for example, the plurality of blocks may be filtered according to the number of positioning requests, the wireless network information, and the like in the blocks.
The acquired historical positioning information can be updated at irregular time to ensure that the data is more accurate, and the positioning accuracy can be further improved.
For example, as shown in fig. 7, historical sample positioning requests of multiple sample terminals may be obtained, the sample positioning requests are screened, a historical positioning request set may be further obtained, a mapping relationship between historical positioning information in the historical positioning request and a block is established, a mapping relationship set is obtained, positioning information in the mapping set is fused, the block is filtered, and a filtered mapping relationship set is finally obtained, where the mapping relationship set may be used for indoor and outdoor determination and auxiliary positioning, for example, a current terminal initiates a target positioning request, and after a server obtains the target positioning request, it may be determined whether the current terminal is in the block, that is, whether the current terminal is indoor or outdoor, or may be in the block, by using positioning information included in the mapping relationship set and target positioning information included in the target positioning request, and may also be in the auxiliary positioning, and determining the geographical position information of the current terminal.
203. The server obtains a target positioning request initiated by the current terminal, wherein the target positioning request comprises the current positioning information of the current terminal.
For example, there is a current terminal that needs to locate the current geographic location, at this time, the current terminal initiates a target location request, and the server may obtain a location request initiated by the current terminal, that is, a target location request, to locate the current terminal.
The current positioning information of the current terminal includes wireless network information, and can be used for matching with the positioning information in the mapping set.
204. And the server matches the current positioning information with the positioning information in the mapping relation set, and determines a target block corresponding to the target positioning information based on the mapping relation set when the target positioning information matched with the current positioning information exists.
For example, during positioning, the server matches the acquired positioning information of the current terminal with the positioning information in the mapping set obtained in step 202, determines the geographical location information of the current terminal according to the matching result, such as whether the current terminal is located in a preset geographical area, and determines the location of the current terminal as a block corresponding to the preset geographical area according to the matched positioning information if the current terminal is located in the preset geographical area.
205. The server takes the target block as the geographic area where the current terminal is located, and outputs the information of the target block.
For example, it is known that the geographic location of the current terminal is the geographic area where the target block is located according to the matching result, and at this time, the information of the target block is output, so that the information of the geographic area where the current terminal needs to be obtained by the current terminal is located can be obtained.
As can be seen from the above, in this embodiment, the historical location request of the multiple sample terminals may be obtained in the certain outdoor geographic area of the large building, where the historical location request includes location information, and then a mapping relationship between the location information in the historical location request and the certain outdoor geographic area of the large building is established to obtain a mapping relationship set, where the certain outdoor geographic area of the large building may be divided into multiple blocks, and then the current location information in the current location request of the current location terminal is matched with the multiple location information to determine whether the location of the current terminal is located in the certain outdoor geographic area of the large building, and when the current location information exists in the certain outdoor geographic area of the large building, the location of the current terminal is determined to be a specific block of the multiple divided blocks, which may improve the accuracy of indoor and outdoor determination, the accuracy of the positioning can also be improved.
