For solve traditional technology in route guidance information show accuracy deficiency technical problem, in the present embodiment
In, spy proposes a kind of display methods of driving trace, and the realization of this method can be dependent on computer program, the computer program
It can run on the computer system based on von Neumann system, which can be based on smart phone, electronics
Navigation equipment etc. is equipped with the electronic map of terminal device or the answering for route guidance of positioning system (such as GPS positioning system)
Use program.The computer system can be the above-mentioned computer program of operation such as smart phone, tablet computer, PC
Terminal device.
Specifically, as shown in Figure 1, the display methods of above-mentioned driving trace includes the following steps S102-S108:
Step S102: current navigation routine is obtained.
It should be noted that the terminal that the display methods of above-mentioned driving trace is based on further includes that can show electronic map
And the user terminal or electric terminal of navigation routine, the user terminal can be the corresponding user terminal of vehicle, be also possible to
The electric terminal of such as smart phone of user.
User by input starting point, terminal to obtain route guidance in the case where, the starting point that can be inputted according to user, end
Point calculates navigation routine, and according to preset navigation routine selection rule (such as route it is most short, expend that the time is most short, traffic lights
It is minimum etc.) optimal navigation routine is selected in the multiple navigation routines being calculated, and show in the display interface.Then real
When the location information for obtaining the terminal devices such as vehicle termination or smart phone corresponding to user, and according to obtaining in real time
Location information and best navigation routine navigate.
The current navigation routine obtained in this step can be the navigation by obtaining specified starting point, terminal obtains
Route is also possible in certain navigation because yawing the navigation routine after recalculating.In the present embodiment, it needs to illustrate
, current navigation routine can also be the navigation routine shown on the display interface of electric terminal.
Specifically, the prominent route track shown shown in number L is as current in application scenarios as shown in Figure 2
The Present navigation route of route guidance, number S are the position that electric terminal current driving is arrived.
Step S104: the first sampling time point of present sample and the location information of the first anchor point are obtained.
In the present embodiment, during showing navigation routine, it is also necessary to be shown on navigation routine corresponding with user
Electric terminal perhaps vehicle location information for example, passing through the displaying mark corresponding with electric terminal or vehicle in displaying
Know the location information of object identity user.In the present embodiment, it when obtaining the location information of user, needs by corresponding with user
The positioning system of electric terminal itself obtains its corresponding location information, for example, passing through vehicle positioning system, smart phone
Positioning system etc. obtains the corresponding location information of user location.
It should be noted that in the present embodiment, can be the location information for obtaining user in real time, i.e., brushed according to CPU
The new period sends the location information of electric terminal to server and is updated by location information of the server to user, or
Person can also be that according to the preset sampling period electric terminal timing sends the location information of electric terminal to server, then
Corresponding location information is updated by server.In the successful situation of updating location information of electric terminal, by electronics
The primary update of the location information of terminal is known as primary sampling, i.e., carries out to the location information of electric terminal present position
Primary sampling, and obtain the corresponding sampling time point of sampling and the corresponding location information of sampled point, wherein location information can be
The corresponding coordinate information of sampled point.
It should be noted that in general, in the case where being travelled according to navigation routine, vehicle or user place
Position must be on navigation routine, if not may be if navigation routine is said yawed or positioned occurred accidentally
Difference.In the case where yawing, needs to trigger preset yaw process flow and handled.But if there is no occur
Yaw, and only because the error of positioning, causes sampled point not on navigation routine, and actually where vehicle or user
Position but on navigation routine；In this case, it needs to calculate the corresponding sampled point of present sample and navigation routine occurs
Deviation, in the case where deviation is sufficiently small, it is believed that the position error in the case where precision allows only occur；And it samples
In the case that deviation between the position and navigation routine of point is more than a certain range, it must not believe that in only precision allowed band
Position error.
Specifically, the distance between the sampled point and navigation routine, example can be calculated by the location information of sampled point
Such as, the minimum value of the distance between all data points for being included using sampled point and navigation routine is as sampled point and navigation road
The distance between line, and in the case where the distance is less than preset distance threshold, it is believed that the position of user in present sample
Or in navigation routine, the phenomenon that yaw.
In the present embodiment, it is thus necessary to determine that whether the sampled point (i.e. the first anchor point) of present sample is on navigation routine.
If in the case where sufficiently small at a distance from some the data point time for being included on the location information of sampled point and navigation routine,
It determines that the sampled point, and can be using the data point as data point corresponding with the sampled point on navigation routine, and can use
The data point substitutes the sampled point.
In another embodiment, it is contemplated that position error, in certain model at a distance from sampled point is between navigation routine
When enclosing interior, also the sampled point is determined as with navigation routine being matched.Specifically, being believed according to the positioning of first anchor point
Breath calculates the distance between first anchor point and the navigation routine, is less than the feelings of preset distance threshold in the distance
It under condition, determines that first anchor point and the navigation routine are matched, and will determine on the navigation routine with described first
The smallest data point in the distance between site is as first anchor point.
Conversely, determining described first in the case where the minimum range is greater than or equal to the preset distance threshold
Anchor point and the navigation routine mismatch, and trigger preset yaw process flow.
Step S106: by the location information of first sampling time point of the present sample and first anchor point
It is compared with the location information of the second sampling time point of last time sampling and the second anchor point, the determining and present sample
Corresponding sampling time interval and the sampling interval distance in the sampling time interval on the navigation routine.
After getting the location information of the corresponding sampling time point of present sample and corresponding sampled point, it is also necessary to
Obtain the location information (second of sampling time point (the second sampling time point) and corresponding sampled point that last sampling obtains
The location information of anchor point).It should be noted that in the present embodiment, when upper primary sampling is not present, the second anchor point can
To be the starting point of navigation routine；I.e. in the first time sampling after navigation starts, corresponding preceding primary sampling is not present,
In this case, using the corresponding location information of starting point as the location information of the second anchor point, and the time that navigation is started
As the second sampling time point.
Because in last time sampling, obtaining the location information in user terminal at that time, and the position of the terminal of user is believed
Breath updates in the navigation routine of displaying to the second anchor point.That is, display circle of the navigation routine in current presentation
Position in face, and where the corresponding marker of electric terminal of user is corresponding with the second anchor point.
Between present sample and upper primary sampling, double sampling is there are certain interval time, and user is to corresponding position
It sets it can also happen that certain change, such as according to navigation routine to destination direction running a certain distance.
In the present embodiment, it can be adopted by calculating the first sampling time point of present sample with the second of last time sampling
Time difference between sample time point, to determine the corresponding sampling time interval of double sampling.It should be noted that in the present embodiment
In, sampling time interval can also be determined according to the sampling period, because can be when obtaining the location information of user terminal
It is obtained according to certain sampling period, that is to say, that can also be directly determined between the sampling time according to the sampling period
Every.Specifically, in the sampling period, no change has taken place, or sampling each time can successfully obtain the positioning letter of user terminal
In the case where breath, the sampling period is consistent with sampling time interval；But it changes in the sampling period, or obtaining
It, just can not basis in the case that location information obtains failure (i.e. sampling failure) in the sampling process of the location information of user terminal
Sampling period determines sampling time interval, and can only be according to the time between the first sampling time point and the second sampling time point
Difference determines sampling time interval.
It should be noted that in the present embodiment, when obtaining the location information of user, can also be and adopted according to preset
Sample cycle samples the location information of user's present position.Specifically, also being wrapped before step S104
It includes, obtaining the preset sampling period samples the location information of electric terminal, when obtaining with this time corresponding sampling of sampling
Between point and anchor point location information.
It should be noted that the preset sampling period can be the sampling period of preset fixation, such as 1s, at another
In optional embodiment, the preset sampling period, which can also be, to be calculated according to road conditions or travel speed.Also
It is to say, in this case, the sampling period can be according to road conditions determination, be also possible to according to whether turning or becoming
What road etc. was determined, or determined according to shape of route etc., or determined according to the form speed of user.
Further, in a specific embodiment, determine the process in sampling period may is that obtain it is described current
Road conditions reference value, the road conditions reference value include at least congestion reference value；Obtain the travel speed of the electric terminal；According to institute
State the travel speed of road conditions reference value and/or the electric terminal, the determining and sampling period.
That is, when determining a sampling period, can be according to current road conditions (such as congestion reference value, day
Gas, route track shape) and the travel speed etc. of user be determined.In the case where road conditions congestion, low running speed,
It can choose a biggish sampling period；Road conditions are good, in the faster situation of travel speed, can choose one it is lesser
Sampling period.
Specifically, can be counted according to the preset sampling period with road conditions reference value, travel speed to input computational algorithm
The corresponding sampling period is calculated, is sampled using sampling period as the sampling period being calculated, and using the sampling period.
Further, it according to the location information of the first anchor point and the location information of the second anchor point, can determine
The moving distance of electric terminal corresponding to user in sampling time interval, i.e. sampling interval distance.For example, calculating can be passed through
The distance between first anchor point and the second anchor point are used as sampling interval distance.It should be noted that in the present embodiment, because
It is along navigation routine or along road driving during movement perhaps traveling for user, and route can not
Entirely straight line (such as can be curve or there are the behaviors such as turn, turn around), the mobile track of user is also impossible to all
Straight line, therefore, calculate sampling interval under sampling time interval apart from when, need to calculate the first anchor point and second fixed
Distance of the site based on navigation routine, i.e., when user terminal being moved to the first anchor point along navigation routine from the second anchor point
Need by track length be sampling interval distance.
Step S108: movement speed is calculated according to the sampling time interval and sampling interval distance, in display institute
According to the movement speed when stating navigation routine, will marker corresponding with the electric terminal from second anchor point along institute
It states navigation routine and is moved to first anchor point.
After moving distance of the user terminal in sampling time interval has been determined, that is, it can determine user terminal from second
