Embodiment
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although the disclosure is shown in accompanying drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
Limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
The principle of the present invention is applied to any electronic equipment for including positioner, includes but is not limited to：Wrist-watch, bracelet,
Mobile phone, tablet personal computer, vehicle positioning system etc..
The principle of the present invention is applicable to carry out any positioner of positioning method switching, wherein the positioning method
Including but not limited to：Architecture, wifi positioning, gps positioning or its combination..
Fig. 1 schematically illustrates the method 100 of positioner switching positioning method according to an embodiment of the invention
Flow chart.As shown in figure 1, method 100 starts from step S101, wherein the beating next time according to the prediction of one or many location informations
Point position, wherein the location information includes movement locus, speed and/or acceleration.
As it is well known to the skilled in the art, movement locus refers to movement particles paths traversed in space.
In the present invention, the object that movement locus then refers to be determined according to the one or many location informations obtained when being positioned is in space
Middle motion paths traversed.Alternatively, movement velocity refers to that one or many location informations for being obtained when being positioned are true
The instant movement velocity of fixed object.Alternatively, acceleration of motion refers to the one or many positioning obtained when being positioned
The instantaneous acceleration for the object that information determines.Alternatively, acceleration can be measured by acceleration induction device, or according to twice or
Instant movement velocity, which calculates, more times obtains.
It is known to those skilled in the art that when the track of known object motion, speed and acceleration, these can be based on
Possible movement locus after information prediction object, so as to predict the location information of object.It can use as known in the art
Any suitable method carries out the prediction of the movement locus and location information.
For example, after user abruptly enters tunnel, because gps signal is poor, it is necessary to which positioning method is cut from GPS location
Architecture is changed to, after handover, the track for making this five times positioning according to the GPS location information of 5 times before switching first is bent
Line, and according to the size and Orientation of instantaneous velocity during geometric locus calculating last time GPS location, then, according to acceleration
The instantaneous acceleration (if any) that inductor measures, the time between last time GPS location and first time architecture
Section is run duration, calculates the track of motion in this period, and be derived from prediction gets position ready.
In the method for the invention, can with persistence forecasting next time get position ready, can also occur positioning method cut
When changing, the preceding location information several times in caching is called to get position ready to predict.
After step slol, step S103 is performed, switches positioning method.Preferably, the switching positioning method includes：
The different positioning method signal intensities received according to the positioner calculate corresponding setting accuracy, and use positioning accurate
Exactness highest positioning method is positioned.Such as individually another positioning side can be switched to by a kind of independent positioning method
Formula, Wi-Fi positioning or architecture are such as switched to by GPS location；By a kind of independent positioning method combination can be switched to fixed
Position mode, the combination, Wi-Fi positioning and the combination of architecture of GPS location and Wi-Fi positioning are such as switched to by GPS location
Deng；A kind of independent positioning method can be switched to by integrated positioning mode, such as is cut by GPS location and the Wi-Fi combination positioned
It is changed to GPS location, Wi-Fi positioning or architecture；Another integrated positioning mode, example can be switched to by integrated positioning mode
Wi-Fi positioning and the combination of architecture are such as switched to by GPS location and the Wi-Fi combination positioned.Preferably, determine by GPS
When position mode switches to the combination of other positioning methods or positioning method, switched over using the method for the present invention.
Specifically, for example, when GPS positions in 4 stars, for intensity in 40db, precision is 5 meters；But the situation of architecture
Under, if base station signal strength is in -60db, its precision is at 20 meters or so, and now positioner will select GPS location.
After step s 103, step S105 is performed, wherein actual first after calculating switching positioning method get position ready
With the difference got ready between position predicted.Alternatively, it is actual first after the difference is to get position ready and predicted
Get the absolute distance between position ready.
After step S105, step S107 is performed, when the difference is less than predetermined threshold value, using described real first
The position of getting ready on border is positioned；When the difference is more than predetermined threshold value, then predict that the position got ready is carried out using described
Positioning.
After step S107, step S109 is performed, when when getting position ready and being positioned, improving institute using the prediction
The frequency actually got ready is stated, and continues to calculate the position actually got ready and the difference predicted between the position got ready,
When the position actually got ready and the difference predicted between the position got ready are less than threshold value, switch to described in use
Actual position of getting ready is positioned.
According to embodiment of the present invention, it can be got ready using described actually get ready with the prediction that frequency is got in raising, which ready,
Between difference and user moving speed frequency of the ratio as the actual dot method.Or improve and get frequency ready
Can improve the frequency of getting ready to 2 times, 3 times, 4 times or more times.
After step S109, step S111 is can also carry out, after frequency is got in raising ready, when the position actually got ready
Put when being less than threshold value with the difference predicted between the position got ready, switch to the use actual position of getting ready to be determined
During position, and by it is described it is actual get frequency ready and be reduced to original get frequency ready.
According to an embodiment of the invention, the threshold value can be 20 meters or less, such as can be 15 meters, 10 meters or 5 meters.
In the method for the invention, before positioning method switching and after switching, positioner can use gravity sensor
Carry out auxiliary positioning.
Among real life, various situation for needing to switch positioning method is likely encountered, for example, working as original positioning
Mode signal is too weak, such as when through gap bridge bottom, tunnel or when having too many high building to block, GPS positioning signal will substantially weaken；
Or can use the higher positioning method of positioning precision, using positioning method of more power saving etc..But in switching just
Within a period of time of generation, it is easy to drift about after handover due to getting information ready, hence in so that positioning is also drifted about,
It can not accurately be positioned, have a strong impact on positioning precision.On the other hand, the invention discloses positioner switch positioning method
Method, the user using positioner need switch positioning method when, employ by actual location information with prediction position
The positioning method that information is combined, it is fixed caused by getting position ready and drifting about when switching positioning method to effectively prevent
Position is inaccurate.
