Description
Technical field
The present invention relates to a kind of method of earth magnetism auxiliary indoor positioning.
Background technology
Now, Process of Urbanization Construction is growing, and high building stands in great numbers in city, various megastore, shopping center, hospital, society
Area etc., people stay wherein, often get lost, bring inconvenience.And then there is the technology of various indoor positionings, as wifi,
Bluetooth, ultrasonic wave etc..But when these technologies are specifically used, it may appear that unexpected emergency case, and then can not be into
Row positioning, such as location equipment, signal node not enough power supply, are stopped；Situations such as equipment damage is not found in time.
It is desirable to which travel through localization region by professional gathers earth magnetism fingerprint base manually, the renewal of earth magnetism fingerprint base is slow,
Accuracy is poor；The situation of geomagnetic field variation disorder occurs in certain applications (there is large-scale electromagnetism kind equipment in such as hospital),
And then influence positioning result.
The content of the invention
The present invention provides a kind of method of earth magnetism auxiliary indoor positioning, it is logical to solve current earth magnetism fingerprint base forming method
Cross professional and traversal collection one by one is carried out to partitioning site, be hereafter periodically updated, lead to not ensure earth magnetism fingerprint base
Data are in the problem of last state.
In order to solve the above technical problems, the present invention is achieved through the following technical solutions：
A kind of method of earth magnetism auxiliary indoor positioning, comprises the following steps successively：
A, Indoor environment plane electronics map is built；
B, dividing needs the place of locality magnetic data in localization region；
C, wireless location is carried out by user terminal；Geomagnetic sensor is equipped with user terminal；
If D, positioning successfully, the information that positioning result and geomagnetic sensor gather is uploaded to background service by user terminal
Device；If positioning failure, switch to ground magnetic orientation, geomagnetic sensor locality magnetic orientation information and by user terminal send to
Background server；
E, background server forms and updates fingerprint base, and positioning result is back to user terminal by background server.
Further, according to architectural design drawing, Indoor environment plane electronics map is built.
Further, user terminal is mobile phone.
Further, user terminal is tablet computer.
Further, at least one of wireless location positions for WiFi positioning, bluetooth and ultrasonic wave positions.
Further, in step E, positioning result is back to user's end by background server using earth magnetism fingerprint matching algorithm
End.
Compared with prior art it is an advantage of the invention that：
The present invention positioned for WiFi, bluetooth positioning and ultrasonic wave positioning etc. be on the basis of original indoor positioning, increase ground
Magnetic auxiliary positioning, to make up the situation that indoor positioning function can not be realized by emergency case, is not increasing equipment and human cost
On the basis of, perfect indoor locating system.Compared to the earth magnetism fingerprint collecting method of mainstream, it is not necessary to which professional is to positioning
Region carries out earth magnetism collection, takes full advantage of the convenience and big data information of user terminal collection.
Earth magnetism fingerprint base forming process in the present invention, by user terminal while normal positioning with gathering the node
Magnetic information, positioning result and Geomagnetism Information are uploaded onto the server, and user terminal can be first stored under off-line state, wait to network
When, then upload.Earth magnetism fingerprint base is ultimately formed, and is constantly updated, improves earth magnetism setting accuracy.Avoid in application-specific
There is the situation of geomagnetic field variation disorder in occasion (there is large-scale electromagnetism kind equipment in such as hospital).
