Abstract
The invention discloses a kind of various dimensions accurate positioning method, including possess the device that network positions function, WIFI connect positioning function and GPS location function, comprise the following steps：One, architecture position L1 is obtained by base station；Two, WIFI position location L2 are obtained by WIFI hot spot；Three, GPS location position L3 is obtained by GPS, four, position location L4 is calculated as basic point application Trilateration location algorithms using L1, L2 and L3.By the present invention in that being calculated with various positioning means various with location information devious, then these are for further processing with location information devious and obtain final high accuracy positioning coordinate.
Description
Technical field
The present invention relates to a kind of various dimensions accurate positioning method for being exclusively used in driving system towards generation.
Background technology
With the Rapid Expansion of automobile industry, cost declines so that many families all have the ability to buy and use automobile.And
And the demand such as individual, commercial affairs, expedite the emergence of generation and drive industry, it is broadly divided into that generation after drinking drives, long-distance generation drives and commercial affairs generation drives.It is all on the market
In many generations, drive the system navigation overwhelming majority and are to rely on gps satellite positioning, and this positioning method needs 30 seconds to start the time, while
Positioning has deviation when state of weather is not good, and when not having GPS location, directly using architecture, can not obtain accurate
Location information.
The content of the invention
The technical problem to be solved in the present invention：There is a problem of for existing localization method above-mentioned, there is provided Yi Zhongli
The method positioned jointly with various ways.
Technical solution of the present invention：
A kind of various dimensions accurate positioning method, including possess network positions function, WIFI connection positioning function and GPS location function
Device, comprise the following steps：One, architecture position L1 is obtained by base station；Two, WIFI is obtained by WIFI hot spot and is positioned
Position L2；Three, GPS location position L3 is obtained by GPS, four, it is fixed as basic point application Trilateration using L1, L2 and L3
Position algorithm calculates position location L4.
L4 is filtered by middle position value filtering to location information, then carries out smothing filtering, finally carry out Kalman filters
Ripple.
Beneficial effects of the present invention：
By the present invention in that being calculated with various positioning means various with location information devious, deviation then is carried to these
Location information be for further processing and obtain final high accuracy positioning coordinate.
Specific embodiment：
Embodiment 1：The device of network positions function, WIFI connection positioning functions and GPS location function is intelligence in the present embodiment
Mobile phone, is provided with software for calculation in mobile phone, calculation procedure is as follows：
A) software searches architecture and signal strength information of the periphery more than three using the network positions function of mobile phone；Make
Trilateration location algorithms are used, architecture data are gradually calculated, a location data L1 containing precision is obtained;
B) the multiple open WIFI with location information in connection periphery are connected, and obtain WIFI location datas and signal strength information；
By Trilateration location algorithms, WIFI location datas are gradually calculated.Obtain a location data containing precision
L2；
C) location information L3 is obtained with GPS location；
D) the above-mentioned 3 kinds of data collected are stored using heap mode, three locator values is carried out with Trilateration positioning again and is calculated
Method completes fusion calculation.Obtain value L4；
E) L4 is filtered by middle position value filtering to location information, then carries out smothing filtering and then carry out Kalman filter,
Obtain precision positional information higher.
In step d）It is fixed with 3 kinds with L1, L2 and L3 as three basic points during middle use Trilateration location algorithms
The precision of position mode obtains the final position of mobile phone with this as mobile phone to three distances of basic point.
