the first acquisition module acquires longitude and latitude information of the first equipment in a Global Positioning System (GPS) mode, sends the longitude and latitude information to the server, acquires area information to which the longitude and latitude information returned by the server belongs, and takes the area information as the first position information;

the second position information is the position information determined by the server according to the image information and the modeling information corresponding to the region to which the server belongs.

10. The apparatus of claim 8, wherein,

the first acquisition module acquires longitude and latitude information of the first equipment in a Global Positioning System (GPS) mode, and the longitude and latitude information is used as the first position information;

the second position information is the position information determined by the server according to the image information and the modeling information corresponding to the area after the area to which the first position information belongs is determined by the server.

11. The apparatus of any one of claims 8 to 10,

and the processing module is further used for carrying out scene tracking and scene enhancement according to the second position information to realize augmented reality service.

12. A positioning device, comprising: a third acquisition module and a determination module;

the third obtaining module is configured to obtain image information and first position information from a first device, where the first position information is position information of the first device, and the image information is image information of a surrounding scene of the first device;

the determining module is configured to determine second location information according to the image information and the first location information, and return the second location information to the first device as location information of the first device obtained by positioning.

13. The apparatus of claim 12, wherein,

the first position information is the area information to which the longitude and latitude information returned by the server belongs, which is obtained after the first device sends the longitude and latitude information obtained in a Global Positioning System (GPS) mode to the server;

and the determining module determines the second position information according to the image information and the modeling information corresponding to the region to which the image information belongs.

14. The apparatus of claim 12, wherein,

the first position information is longitude and latitude information acquired by the first equipment in a Global Positioning System (GPS) mode;

the determining module determines a region to which the first position information belongs, and determines the second position information according to the image information and modeling information corresponding to the region.

15. An electronic device, comprising:

at least one processor; and

a memory communicatively coupled to the at least one processor; wherein,

the memory stores instructions executable by the at least one processor to enable the at least one processor to perform the method of any one of claims 1-7.

16. A non-transitory computer readable storage medium having stored thereon computer instructions for causing a computer to perform the method of any one of claims 1-7.

17. A computer program product comprising a computer program which, when executed by a processor, implements the method according to any one of claims 1-7.
