Fig. 1 is the flow chart of the positioning and rectifying method of the embodiment of the present invention.
As shown in figure 1, methods described includes：
Step S100, acquisition current location information and present speed.
Specifically, the API for being provided by the operating system of mobile terminal obtains current positional information and present speed.
The present speed can be considered as judging the status information whether mobile terminal remains static.
Step S200, judge whether the attribute of current location information points out Wrong localization, if it is, performing step
S300, if otherwise performing step S500.
In the application programming interfaces that the operating system of mobile terminal is provided, it will usually which the information to Wrong localization is carried
Show.For example, in the IOS systems of Apple Inc., by the horizontalAccuracy (horizontal accuracy) of CLLocation classes
Whether attribute points out Wrong localization occur.HorizontalAccuracy attributes are that -1 expression should in the identification of operating system aspect
Secondary positioning result is insincere.Thus, under the premise of herein, the prompting of application programming interfaces offer can be based on come first by a part
Incredible location information is abandoned or filtered out.
Displacement between step S300, calculating current location and last effectively position location, and current positioning time
Time difference between the positioning time stamp of stamp and last effectively positioning.
Wherein, effectively positioning refers to, the positional information that this positioning gets is not filtered or abandoned.The displacement can be with
Calculated by the coordinate of current location and the coordinate of last effectively position location.Meanwhile, the positional information for getting every time is all
The timestamp for characterizing positioning time can be attached, just will be seen that the location information for obtaining twice is same based on positioning time stamp
What one moment obtained does not still obtain in the same time.
Step S400, to judge whether present speed, displacement and time difference meet present speed be zero or less than zero, and described
Displacement absolute value and time difference absolute value are all higher than zero, if it is, performing step S500, otherwise perform step S600.
In this step, when present speed is zero, mobile terminal remains static, meanwhile, in practice, if behaviour
The present speed be given as system is less than zero, that is, when velocity sensor gives the speed of mistake, mobile terminal is also
Remain static.If now, the current location information different from the timestamp of preceding once effective positioning deviate from upper one
Secondary position, illustrates to occur in that locating bias under static state, and the information of this positioning should not be adopted.Due to carrying out position
The frequency of acquisition of information (namely carrying out positioning action) is higher, therefore, it is mobile when under mobile terminal remains static
Terminal should be in same position at the moment of positioning action adjacent twice.
Step S500, current location information is set to invalid positioning.
Specifically, the positional information that can will be set to invalid positioning is abandoned or filtered, and it is right not use in the application
The positional information answered, thus, it is possible to ensure not produce skew or saltus step to the position of user feedback or displaying, lifting user uses
Experience.
Step S600, by current location information be set to effectively positioning.
If current location information is arranged to effectively positioning, corresponding positional information can be in the application used
The position of mobile terminal is updated, and to user feedback and displaying.
Thus, judge whether mobile terminal remains static by obtaining status information, be in mobile terminal static
When under state, the positional information and last effectively positioning that will be stabbed with different positioning times relative to last effectively positioning
Positional information compares, if skew (that is, displacement is more than zero) occurs in position, filters or abandon the positional information, is providing
Not used in the program of location Based service.Thus, it is possible to filter out due to the switching of positioning method or other
Cause the locating bias for occurring under static state, improve Position location accuracy, lift user experience.
Fig. 2 is the flow chart of the positioning and rectifying method of another embodiment of the present invention.
As shown in Fig. 2 methods described includes：
Step S100 ', acquisition current location information and course information.
Specifically, the API for being provided by the operating system of mobile terminal obtains current positional information and course information.
The course information can be considered as judging the status information whether mobile terminal remains static.
Step S200 ', judge whether the attribute of current location information points out Wrong localization, if it is, performing step
S300 ', if otherwise performing step S500 '.
Displacement between step S300 ', calculating current location and last effectively position location, and current positioning time
Time difference between the positioning time stamp of stamp and last effectively positioning.
Wherein, effectively positioning refers to, the positional information that this positioning gets is not filtered or abandoned.The displacement can be with
Calculated by the coordinate of current location and the coordinate of last effectively position location.Meanwhile, the positional information for getting every time is all
The timestamp for characterizing positioning time can be attached, just will be seen that the location information for obtaining twice is same based on positioning time stamp
What one moment obtained does not still obtain in the same time.
Step S400 ', judge course information, displacement and time difference whether meet course information keep the scheduled time do not become
Change, and the displacement absolute value and time difference absolute value are all higher than zero, if it is, performing step S500 ', otherwise perform step
Rapid S600 '.
In this step, course information refers to detect that the attitude of the mobile terminal for obtaining is believed by electronic compass or gyroscope
Breath.When under mobile terminal remains static, the attitude of mobile terminal generally also keeps different, therefore, it can based on movement
Terminal course information judges whether it remains static.If the course information of mobile terminal is kept for the scheduled time do not become
Change, then may determine that it remains static.If now, the present bit confidence different from the timestamp of preceding once effective positioning
Breath deviate from the position of last time, illustrate to occur in that locating bias under static state, and the information of this positioning should not be adopted.
Step S500 ', current location information is set to invalid positioning.
Step S600 ', by current location information be set to effectively positioning.
Whether the present embodiment substitutes present speed to judge mobile terminal in static by the course information of mobile terminal
State, there is provided alternative real-time mode.
Fig. 3 is the flow chart of the positioning and rectifying method of another embodiment of the invention.
As shown in figure 3, the present embodiment positioning and rectifying method includes：
Step S100 ", acquisition current location information and present speed and course information.
Specifically, the API for being provided by the operating system of mobile terminal obtains current positional information and present speed.
It is used to judge that the status information whether mobile terminal remains static includes present speed and course information in the present embodiment.
Step S200 ", judge whether the attribute of current location information points out Wrong localization, if it is, performing step
S300 ", if otherwise performing step S500 ".
Displacement between step S300 ", calculating current location and last effectively position location, and current positioning time
Time difference between the positioning time stamp of stamp and last effectively positioning.
Step S400 ", to judge whether present speed, course information, displacement and time difference meet present speed be zero or small
In zero and course information is kept for the scheduled time be not changed in, and the displacement absolute value and time difference absolute value are all higher than zero,
If it is, performing step S500 ", otherwise perform step S600 ".
In this step, course information refers to detect that the attitude of the mobile terminal for obtaining is believed by electronic compass or gyroscope
Breath.As a rule, it is most accurate to judge whether mobile terminal remains static by the present speed of mobile terminal.But
It is in some cases, due to speed computational algorithm or the problem of sensor accuracy, mobile terminal walking to be carried in user
When, because speed is slower, the present speed that the operating system of mobile terminal is obtained also is zero or negative value, now, mobile terminal reality
Inactive state is not on border.Correspondingly, its current location and the displacement of last effectively position location are not skew, and
It is likely to actual displacement.Thus, only judge whether to remain static by present speed to cause for position
The mistake filtering of information.In the present embodiment, increase course information to aid in being judged, mobile terminal walking is carried in user
When, due to human body dipping and heaving, the attitude of mobile terminal can keep change.Because the accuracy that attitude or course are detected is higher,
This less attitudes vibration can be detected by mobile terminal.Therefore, in the present embodiment, it is zero only in present speed
Or less than zero and course information keep the scheduled time be not changed in just judgement think that mobile terminal remains static.If this
When, the current location information different from the timestamp of preceding once effective positioning deviate from the position of last time, illustrate in static shape
Locating bias are occurred in that under state, the information of this positioning should not be adopted.
Step S500 ", current location information is set to invalid positioning.
Step S600 ", by current location information be set to effectively positioning.
Thus, the present embodiment can further increase the accuracy of method for correcting error, reduce and filtered for the mistake of positional information.
