Fig. 1 is the flow chart of the processing method of GPS location data according to embodiments of the present invention.As it is shown in figure 1, should Method may include steps of:

Step S102, obtains multiple location points of the destination object that GPS terminal collects.Wherein, location point can wrap Include at least one location parameter.Specifically, GPS terminal according to default collection rule (as each second gathers once or often Two seconds gather an inferior collection rule, specifically can be according to the configuration parameter of GPS terminal depending on, this is not limited by the present invention Fixed) within a period of time, gather the multiple of destination object (such as GPS terminal or the user of handhold GPS terminal) Location point, and, each location point include at least one location parameter (as speed, the time, longitude, latitude and Towards etc.).

Such as, GPS terminal gathers the location point of a destination object each second, then in a period of time (such as 1.5 points Clock) in, GPS terminal will collect 90 location points；In the case of network condition is poor, GPS terminal collects The number of location point may tail off, as only collected 60 location points.

In this embodiment, these location points collected potentially include noise, offset point or shift point etc. abnormal Data, before reporting the location point of destination object, based on needing the multiple location points that will collect, parameter is carried out Process, using determine one accurately and effectively location point as the position of destination object.

Multiple location points are screened by step S104 according to default screening rule, and location point screening obtained Add in Trusted List as active position point.Specifically, can be according to the location parameter of location point to collecting Multiple location points screen, and to give up inoperative position point (such as noise, offset point or shift point etc.), retain effectively Location point.

Alternatively, according to default screening rule, multiple location points are carried out screening may include steps of:

Step S1, it is judged that the angle parameter of location point whether more than the first predetermined angle, location point height above sea level whether More than preset height and location point towards whether preset towards in the range of.Wherein, at least one location parameter is also Including angle parameter, height above sea level and towards.

It should be noted that the angle parameter of location point be not more than the first predetermined angle, location point height above sea level not More than preset height and location point towards not preset towards in the range of in the case of, perform step S3；In position The angle parameter of point more than the first predetermined angle, location point height above sea level more than preset height and location point towards Preset towards in the range of in the case of, perform step S5.

Step S3, gives up location point.

Step S5, adds to location point in coordinate points list according to default delivery parameter.

Wherein, angle parameter, height above sea level and towards being the initial data that GPS terminal collects.

In an optional embodiment, the first predetermined angle can be 2, preset height can be 100 meters and pre- If towards may range from 2 to 1000.The most in this embodiment, when the angle parameter of location point be not more than 2, sea Degree of lifting is not more than 100 meters or towards time not in the range of 2 to 1000, then judge that this location point is invalid bit Put a little, and this location point is given up；Otherwise, then this location point is retained.According to above-mentioned first predetermined angle, preset height Degree and preset towards scope, all location points collected are screened after, all location points that will remain Add in coordinate points list according to default delivery parameter.

It should be noted that above-mentioned first predetermined angle, preset height and preset can according to GPS eventually towards scope End concrete application scenarios and arrange, the numerical value in above-described embodiment only makees exemplary illustration, and the present invention is not to first Predetermined angle, preset height and preset be defined towards scope.

By the above embodiment of the present invention, based on the first predetermined angle, preset height and preset towards scope collection To location point carry out a Preliminary screening, give up substantially abnormal location point (if height above sea level is the position of-1000 Point), thus provide relatively accurate basic data for subsequent treatment, to improve the efficiency of subsequent treatment.

Further, according to default delivery parameter location point added in coordinate points list and may include that according to taking All location points are grouped by mould parameter；By group, location point is added in coordinate points list, wherein, coordinate points list Number is consistent with the group number packet of all location points obtained, and comprises one group of location point in each coordinate points list.

Specifically, according to default delivery parameter, all location points remained in above-described embodiment are grouped, And the location point belonging to same group is added in same coordinate points list.Alternatively, one can be obtained after packet Group or organize location point more, corresponding, one or more coordinate points list, the i.e. number of coordinate points list will be obtained Consistent with the number of the group that packet obtains.

Such as, GPS terminal has collected 90 location points, according to the first predetermined angle in above-described embodiment, presets Height and preset towards scope, 90 location points collected are screened after, the location point remained has 80, now, according to default delivery parameter (such as 30), these 80 coordinate points are grouped, three will be obtained The most every 30 of 80 location points optionally, can be divided into one group, the conduct less than 30 one group by group. After the grouping, the location point (quantity of the location point often organized is respectively 30,30,20) of these three group is added respectively It is added in three coordinate points lists.

And for example, GPS terminal has collected 60 location points, according to the first predetermined angle in above-described embodiment, presets Height and preset towards scope, 60 location points collected are screened after, the location point remained has 40, now, according to default delivery parameter (such as 40), these 40 coordinate points are grouped, one will be obtained Group, adds to this location point (quantity of location point is 40) organized in a coordinate points list.

In the above embodiment of the present invention, according to the delivery parameter preset to location point added in coordinate points list it After, above-mentioned method can also comprise the steps:

Step S2, judge successively the angle parameter of each location point in coordinate points list whether in the range of predetermined angle, Whether the calculating speed of each location point is in the range of the first pre-set velocity and whether the speed of each location point is second In the range of pre-set velocity.Wherein, the calculating speed of a location point is the shifting of the corresponding previous location point of a location point Dynamic speed.

Wherein, the angle parameter of the location point in coordinate points list is not in the range of predetermined angle, the calculating of location point Speed not in the range of the first pre-set velocity or the speed of location point not in the range of the second pre-set velocity in the case of, hold Row step S4；The angle parameter of the location point in coordinate points list is in the range of predetermined angle, the calculating speed of location point Degree in the range of the first pre-set velocity and the speed of location point in the range of the second pre-set velocity in the case of, perform step Rapid S6.

Step S4, gives up location point.

Step S6, determines that location point is the location point that screening obtains.

Specifically, if after adding location point to coordinate points list according to default delivery parameter, obtain a seat Punctuate list, then judge the angle parameter of each location point in this coordinate points list whether in the range of predetermined angle, Whether the calculating speed of each location point is in the range of the first pre-set velocity and whether the speed of each location point is second In the range of pre-set velocity；If after adding location point to coordinate points list according to default delivery parameter, having obtained many Individual coordinate points list, then be performed both by above-mentioned judgement operation to each coordinate points list.

Below a coordinate points list to be judged the explanation of operation is discussed in detail the above embodiment of the present invention.

In an optional embodiment, predetermined angle may range from the 3 to 43, first pre-set velocity and may range from 0 to 98 metre per second (m/s) and the second pre-set velocity may range from 3.32 to 400 metre per second (m/s)s.The most in this embodiment, When the angle parameter of location point not in the range of 3 to 43, calculate speed not in the range of 0 to 98 metre per second (m/s) or When person's speed is not in the range of 3.32 to 400 metre per second (m/s)s, then judge that this location point is inoperative position point, and should Location point is given up；Otherwise, then retain this location point, and determine the location point obtained as screening by this location point.? In this embodiment, according to above-mentioned predetermined angle scope, the first pre-set velocity scope and the second pre-set velocity scope to warp The location point crossing Preliminary screening screens again, can remove irrational location point further, improves GPS fixed The accuracy of position.

It should be noted that above-mentioned predetermined angle scope, the first pre-set velocity scope and the second pre-set velocity scope can Arranging with the concrete application scenarios according to GPS terminal, the numerical value in above-described embodiment only makees exemplary illustration, this Bright predetermined angle scope, the first pre-set velocity scope and the second pre-set velocity scope are not defined.

By the above embodiment of the present invention, preset speed based on predetermined angle scope, the first pre-set velocity scope and second Location point through Preliminary screening is screened by degree scope again, gives up out-of-the way position point further, thus after being Continuous process provides basic data more accurately, to improve the efficiency of subsequent treatment further.

Need it is further noted that calculate speed be the time according to current location point, current location point previous The calculated speed of distance between time and the two location point of location point, illustrates current location point relative Translational speed in its previous location point；Angle parameter and the speed of each location point then collect for GPS terminal Initial data.

According to the above embodiment of the present invention, location point screening obtained adds in Trusted List as active position point May include that whether the angle parameter of the active position point judged in each coordinate points list is more than the second predetermined angle； If the angle parameter of active position point is more than the second predetermined angle, then one mark is set for active position point；If effectively The angle parameter of location point is not more than the second predetermined angle, then judge whether the speed of active position point is preset more than second Speed；If the speed of active position point is more than the second pre-set velocity, then one mark is set for active position point；Judge Whether the number of the mark corresponding to all active position points of each coordinate points list is more than predetermined threshold value；If coordinate points The number of the mark corresponding to all active position points of list is more than predetermined threshold value, then judge each active position point It is motor point, and each active position point is added in Trusted List as motor point, wherein, a coordinate points The corresponding Trusted List of list；If the number of the mark corresponding to all active position points of coordinate points list is not more than Predetermined threshold value, then judge that each active position point is rest point, and added as rest point by each active position point It is added in Trusted List.

Specifically, location point screening obtained is as active position point, if according to default delivery parameter by location point After adding coordinate points list to, obtain multiple coordinate points list, the most respectively effective in each coordinate points list Location point is performed both by above-mentioned judgement operation, in this case, each coordinate points list by obtain one corresponding can Letter list；If after adding location point to coordinate points list according to default delivery parameter, obtain a coordinate points List, the active position point in this coordinate points list performs above-mentioned judgement operation the most respectively, and obtain one corresponding Trusted List.

Illustrate as a example by a coordinate points list below.

In an optional embodiment, the second predetermined angle can be the 43, second pre-set velocity can be 0.So In this embodiment, when the angle parameter of active position point is more than 43, then one mark is set for this active position point； Otherwise, then continue to judge that whether the speed of this active position point is more than 0；When the speed judging this active position point is big In 0 time, then one mark is set for this active position point.If the angle parameter of active position point be not more than 43 or The angle parameter of active position point more than 43 but no more than 0, then mark is not set for this active position point.

In this embodiment, after being performed both by all active position points in coordinate points list judging operation, system Count the number of the mark of all active positions point, and (such as 5, this is pre-to judge the number of mark whether to be more than predetermined threshold value If threshold value can set according to practical situations, this is not limited by the present invention)；Number in mark is more than to be preset In the case of threshold value, it is judged that active position point is motor point；Otherwise, then judge that active position point is rest point. And using each effectively till add in a Trusted List as motor point or rest point.

Alternatively, in this embodiment, in order to improve the accuracy of judged result, when judging that active position point is for fortune During dynamic point, it is also possible to judge again this active position point towards whether presetting towards threshold value (such as 1000) less than first； When judging that active position point is rest point, it is also possible to judge the most pre-less than second towards whether of this active position point again If towards threshold value (such as 20).When the active position point as motor point towards presetting not less than first towards threshold value or Person when the active position point as rest point towards not less than second preset towards threshold value time, then it is assumed that this active position Point is abnormity point, and is given up；When presetting towards threshold value towards less than first of the active position point as motor point Or when the active position point as rest point towards less than second preset towards threshold value time, then it is assumed that this active position Point is effective point, and is added in Trusted List.

By the above embodiment of the present invention, according to above-mentioned second predetermined angle and the second pre-set velocity to active position point Kinestate judges, can effectively judge that destination object is to be in resting state at kinestate, thus Improve the accuracy of GPS location further.

It should be noted that above-mentioned second predetermined angle and the second pre-set velocity can be according to the concrete application of GPS terminal Scene and arrange, the numerical value in above-described embodiment only makees exemplary illustration, the present invention not to predetermined angle scope, One pre-set velocity scope and the second pre-set velocity scope are defined.

Step S106, calculates the average speed of each active position point in Trusted List.Specifically, from Trusted List Read the speed of each active position point respectively；Calculate the meansigma methods of the speed of each active position point read, make Average speed for each active position point.

In this embodiment, when only obtaining a Trusted List, calculate each active position point in this Trusted List Average speed can obtain an average speed value；When obtaining multiple Trusted List, calculate multiple credible row respectively The average speed of each active position point in table can obtain multiple average speed value.So obtain based on average speed The number of the credible some position arrived is just consistent with the number of Trusted List.

Step S108, it is judged that whether average speed is the first pre-set velocity.Alternatively, the first pre-set velocity can be 0.

Wherein, in the case of judging that average speed is the first pre-set velocity, perform step S110；Put down judging In the case of all speed is not the first pre-set velocity, perform step S112.

Step S110, obtains the meansigma methods of each location parameter of all active positions point, and according to each location parameter Meansigma methods determine a trustworthy location point.Wherein, trustworthy location point is used for indicating destination object location.

Specifically, for a Trusted List, when the average speed of its correspondence is the first pre-set velocity, obtaining this can Each location parameter (e.g., time, angle, longitude, latitude and speed etc. of all active position points in letter list Deng) meansigma methods, and according to the meansigma methods of each location parameter determine a point (this point for according to location parameter on ground A point of location on figure) as trustworthy location point, to indicate destination object location.

In this embodiment, for multiple Trusted Lists, then each Trusted List is performed both by aforesaid operations, thus can To obtain multiple trustworthy location point.

Step S112, obtains the speed of all active positions point and the difference of average speed, and by the difference with average speed Active position corresponding to the speed point of value minimum is as trustworthy location point.Wherein, at least one location parameter includes speed Degree.

Specifically, for a Trusted List, when the average speed of its correspondence is not the first pre-set velocity, then obtain The speed of all active position points and the difference of average speed in this Trusted List, and by corresponding to speed minimum for difference Active position point as trustworthy location point, to indicate destination object location.
