Step S2, user updates current GPS information when placing anchor point, and extracts the corresponding characteristic of current preview stream
(i.e. set of image characteristics)；
Step S3, saving with current GPS data is the anchor point information and corresponding characteristic marked, and uploads to cloud
(the i.e. described server)；
Step S4, return step S2 terminate until AR application is closed；
Wherein, the implementation process of localization method, as shown in figure 4, at least including the following steps S0 to step S7:
Step S0 opens AR application, starts；
Step S1, when starting positioning, mobile phone opens GPS positioning module and camera, is updated periodically GPS information, phase
Machine obtains preview stream in real time；
Step S5 searches corresponding anchor map according to current GPS information to cloud；If cloud is not present with current GPS letter
Breath is the anchor point map of label, then the query actions of step S5 are repeated when GPS information changes；If cloud exists with current
GPS information is the anchor point map of label, thens follow the steps S6；
Step S6, downloading corresponding anchor map to mobile phone；
Step S7, according to current preview stream and the anchor point map real-time matching downloaded；Successful match thens follow the steps
S8；It fails to match, then repeatedly step S7；
Step S8 shows existing anchor point information at camera current visual angle (i.e. current shooting interface)；
Wherein, the implementation process of map updating method at least includes the following steps:
Step S9, after anchor point map is downloaded successfully, if newly-increased anchor point, executes above-mentioned steps S3；After positioning successfully, to
Anchor point is deleted, then sends current anchor label (i.e. anchor point mark) to cloud, cloud is notified to delete corresponding anchor point information and spy
Levy data.
Above-mentioned process is made a concrete analysis of and described below.
In step S1, GPS hardware mould group and camera mould group in mobile phone are relied on, it can be real-time by operating system standard interface
Obtain GPS data and preview stream.The GPS information generally obtained includes the longitude and latitude and height of current location, and preview stream can be
The image data of the formats such as YUV, RGB.
In step S2, the longitude and latitude and height (In of current location are got when user places anchor point by GPS hardware mould group
Generally without using height in actual location) because longitude and latitude data are inconvenient in actual location use, generally pass through Geo Hash
Longitude and latitude 2-D data is encoded to a character string by algorithm.Concrete principle and workflow are as follows:
1, latitude (- 90,90) is divided into two sections (- 90,0), (0,90), if the latitude value of coordinate position exists
First interval, then coding is 0, is otherwise encoded to 1.It illustrates, belongs to (0,90) due to 39.918118, institute with 39.918118
To be encoded to 1, then proceed to for (0,90) to be divided into (0,45), (45,90) two sections, and 39.918118 are located at (0,45), institute
It is 0 with coding, and so on, 20 fractionations are carried out, finally calculating 39.918118 coding is
10111000110001011011；The processing of longitude be also it is similar, only the range of longitude is (- 180,180), 116.40382
Coding be 11010010110001101010；
2, the coding of longitude and latitude merges, and since 0, odd number is is latitude, and for even number to be longitude, obtained coding is 111
0011101001000111100000011100111001101；
3, the coding after the merging of pair warp and weft degree carries out base32 coding, finally obtains wx4g0ffe.
Pair warp and weft degree more only needs to compare character string after above-mentioned variation, realizes from two dimension to one-dimensional change
It changes.
In step S3, corresponding current GPS Geo Hash Code of current anchor is saved after aforesaid operations, to should
The characteristic and anchor point information of preceding preview stream, and anchor point is numbered, the anchor point with identical Geo Hash forms anchor point
Map.
In step S5, corresponding level-one positioning, due to GPS data error, in same place, its error amount may be in 100m model
Left and right is enclosed, corresponding to the corresponding digit of Geo Hash is the 7th, when doing level-one positioning using GPS matching, only needs to match
To the 7th.
In step S6, two-stage positioning is corresponded to, corresponding map is downloaded after GPS successful match and passes through two-stage positioning again, is i.e. ORB is special
Matched mode is levied, determines whether the photographed scene of current preview stream is consistent with the photographed scene saved when placing anchor point.
Extraction and matching for set of image characteristics, it is known that how two images determine that two images are the same scenes,
Can be by finding the characteristic point of this two images, and describe the attribute of these characteristic points, if this two images have it is enough
Characteristic point attribute having the same, it is judged that this two images are a scenes.
In step S9, in above process at any time may there is a situation where user increase newly anchor point, when user place anchor point when
It is normal to execute step S2 and S3 process.The scene of deletion anchor point may occur after anchor point successful match, delete anchor point
When corresponding anchor point need to only be numbered (anchor point mark) notice cloud so that cloud delete corresponding anchor map in anchor point letter
Breath.
