It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the application in detail in conjunction with the embodiments.
Please refer to Fig. 1, it illustrates the exemplary process diagram of the navigation data disposal route according to the application's embodiment.In the present embodiment, the method can be applied to and comprise in the terminal device of navigational system.This terminal can comprise smart mobile phone, intelligent watch, Intelligent navigator, personal digital assistant (Personal Digital Assistant, PDA), panel computer etc.Terminal device can have radio communication function, carries out data interaction by network and the server preserving navigation data.
It should be noted that and not only can be applied to the navigation data disposal route that the application provides in above-mentioned terminal device, can also be applied in navigation server.In certain embodiments, some steps in navigation data disposal route can perform in terminal device, and other steps can realize in navigation server, carry out data interaction and information transmission between navigation server and terminal device by network.
As shown in Figure 1, in a step 101, trace information and the locating information of navigational system is obtained.
In vehicle travel process, navigational system can record the path of traveling, forms continuous print trace information.In the present embodiment, in-vehicle navigation system recorded data can be transferred to obtain trace information.Also can Real-Time Monitoring vehicle location, vehicle location in driving process is coupled together according to time sequencing, forms the trace information of navigational system.Trace information can be made up of the data message in multiple section, and the data message in each section can have unique identifier.This identifier can be time identifier, can be also geographic location identifier, can also be the identifier that time and geographic position combine.The data message in multiple section can be stored in navigational route database, and distinguish the data message in each section with identifier.
Trace information can include the trace information of navigation data and the trace information without navigation data.Wherein, the route information that the trace information of navigation data can travel based on the navigation information that existing navigation data generates according to navigational system for vehicle is had.The trace information obtained under can comprising following two kinds of situations without the trace information of navigation data: a kind of situation is when vehicle drives in navigational route database the section not having related data, and the trace information of the route of vehicle actual travel as this section can be preserved by navigational system.Another situation is the navigation error due to navigational system, the section of having preserved related data in some navigational route databases also there will be the situation without navigation data, at this moment, the trace information of the route of vehicle actual travel as this section also can be preserved by navigational system.
When there is not the data message in the section that Current vehicle travels in navigational route database, think that this section may for new road.At this moment, the trace information without navigation data is contained in trace information.This trace information without navigation data can be recorded by the locating information of multiple positions of monitor vehicle or people and be stored.
In certain embodiments, navigational system record and save include navigation data and without the trace information of navigation data after, automatically real-time or with the certain hour cycle preserved trace information can be reported navigation server, navigation server can receive the trace information that multiple navigational system reports, trace information is further processed, to obtain more accurate road data.
The locating information of navigational system can be passed through GPS (Global Positioning System, GPS) and obtain.This locating information can be the 2-D data comprising longitude and latitude data.In certain embodiments, this locating information can also be the three-dimensional data comprising longitude, latitude and altitude information.
In some implementations, the trace information of navigational system can be obtained in the following way: the user totem information obtaining navigational system, extract the trace information of navigational system according to user totem information.Wherein user totem information can be user identification code, such as called subscriber's identifier (Called User Identification number, CUID).When navigational system detects the trace information without navigation data, the CUID of self can be sent to navigation server.Navigation server can send data to the navigational system corresponding to this user totem information and extract order, receives the trace information that navigational system sends in response to this order.Further, can by obtaining the trace information of multiple navigational system with upper type.
With further reference to Fig. 2, it illustrates the effect schematic diagram of the trace information of navigational system.As shown in Figure 2, the trace information in three sections 201,202 and 203 is comprised in the trace information of navigational system.Wherein 201 and 202 for there being the section of navigation data, and 203 is the section without navigation data.In actual applications, navigational system, in navigation procedure, can be identified in navigational route database the identifier searching current road segment, to obtain the navigation data of respective stretch.Such as, the navigation data in section 201 and 202 can obtain by searching in navigation data for key word with its geographical location information.When navigational system runs into the section without navigation data, such as enter from section 201 section 203 (to arrive Fig. 2 position a) time, can search with the identifier in section 203 in navigational system, lookup result is the navigation data in not this section in navigational system.At this moment, vehicle can travel according to real road, and navigational system can the GPS information of registration of vehicle actual travel, and GPS information is preserved in chronological order, forms the trace information in this section.At this moment vehicle is in car mark free state.Owing to there is not the navigation data in section 203 in navigational system, therefore, the GPS information in this section that multiple navigational system records may be incomplete same, and multiple navigational system may exist deviation between the trace information in this section.Such as five trace informations in 2031,2032,2033,2034,2035 expression sections 203 shown in Fig. 2.The data that these five trace informations can generate for multiple navigational system also can be that same navigational system is at different time recorded data.When vehicle enters section 202 (arriving position b Fig. 2) from section 203, navigational system can search the navigation data in section 202, and vehicle can travel according to navigation data, and trace information can be the trace information in section 202 in navigational route database.
In a step 102, the trace information without navigation data in trace information is extracted.
In the present embodiment, after the trace information that acquisition navigational system is preserved, can extract wherein without the trace information of navigation data.Concrete extracting method can be: mated with the data in navigational route database by trace information, intercepts the trace information that wherein cannot mate, is the trace information without navigation data.
In certain embodiments, navigational system is recognizing current road segment without navigation data, when namely not finding the identifier of current road segment in navigational route database, current geographical location information can be reported by navigation server in real time, and report at a certain time interval in the driving process in this section, until vehicle travels to the section having navigation data.Like this, navigation server just can receive the geographical location information of vehicle on this section, thus can obtain this trace information without navigation data.
In step 103, determine without the track link information corresponding to the trace information of navigation data based on locating information.
Track link information can comprise navigational system and be converted to Site Survey information without navigation data from there being navigation data, and picks out point location information from what be converted to navigation data without navigation data.This locating information can be GPS information, comprises longitude data and latitude data.In the present embodiment, the locating information that can obtain based on navigational system in step 101 determines the GPS information of two end points of the trace information without navigation data, forms index relative, such as, can form array L (Linkin, Linkout).Wherein, Linkin can represent from there being navigation data to be converted to Site Survey information without navigation data, namely without the locating information of the beginning end points in the section of navigation data; Linkout can represent the contact point locating information from being converted to navigation data without navigation data, namely without the locating information of the end caps in the section of navigation data.
At step 104, the whether corresponding new road net data of trace information without navigation data is judged according to track link information.
When navigational system recognizes the section without navigation data, due to GPS locator data possibility out of true in some navigational system, the navigation way of navigational system may occur that track drifts about, and at this moment navigational system also can may not identify link identifier.Therefore, if the recognition result only returned according to a navigation terminal just determines that this section is new road net data, then the trace information likely drifted about by track is as new road net data, and the possibility of result drawn is inaccurate.In the present embodiment, the track link information that can return based on multiple navigational system judges the whether corresponding new road net data of the recognized trace information without navigation data, to ensure the accuracy of new road net data.
Usually, the locating information of multiple navigational system on same section may be identical or close.After the trace information without navigation data obtaining multiple navigational system and track link information, according to the Site Survey information in track link information or the whether corresponding new road net data of the whether identical or close trace information judging to extract of point location information can be picked out.Such as, the track link information without navigation data of multiple navigational system can be obtained, and search the trace information whether having same trajectories link information, if had, then can think the corresponding new road net data of this trace information.If do not find the trace information of same trajectories link information, then can think the not corresponding new road net data of this trace information.
In some optional implementations, the trace information whether corresponding new road net data that can judge without navigation data based on the quantity of identical or akin track link information.With further reference to Fig. 3, it illustrates according to the judgement of the application's embodiment exemplary process diagram without the method for the whether corresponding new road net data of trace information of navigation data.
As shown in Figure 3, in step 301, travel through all trace informations, set up track link information and without navigation data trace information between mapping relations.
In the present embodiment, to each trace information obtained, can extract wherein without the trace information of navigation data, and determine without the track link information corresponding to the trace information of navigation data according to locating information, set up track link information and without navigation data trace information between mapping relations.In some implementations, the identifier in section can be adopted to represent trace information, such as can indicate trace information without navigation data with Track, then can by without the trace information Track of navigation data and track link information (track index) L (Linkin, Linkout) mapping corresponding relation F (L, Track) is set up.
Navigation server can travel through the trace information of obtained multiple navigational system, set up with or without the mapping corresponding relation between the trace information of navigation data and track link information.Alternatively, the mapping relations with identical or akin track link information can also be carried out cluster, to judge the whether corresponding new road net data of trace information without navigation data further.
In step 302, judge whether the quantity of the mapping relations that same track link information is corresponding exceedes predetermined value.
Whether in the present embodiment, can set a predetermined value, be the basis for estimation of new road net data as the trace information judged without navigation data.The quantity of the trace information without navigation data corresponding to same track link information and the mapping relations F (L, Track) between track link information can be added up.Particularly, mapping relations quantity corresponding to same track link information can be added up according in step 301 based on the cluster result of track link information to mapping relations.
In some optional implementations, above-mentioned predetermined value can be determined based on the mode of following machine learning: first based on the trace information of multiple navigational system and actual road net data structure training set and test set; Afterwards training set is trained, determine the initial value of predetermined value; Then based on test set, correction optimization is carried out to the initial value of predetermined value, obtain the optimal value of predetermined value.Training set and test set can have identical data structure, and wherein can comprise positive sample and negative sample.Positive sample can be trace information and actual road net data accurately, and negative sample can for the trace information of track drift and actual road net data occur.An initial value can be obtained by training, test set then can be adopted to test initial value, and adjust this initial value according to test result, finally obtain an optimal value, as the predetermined value of mapping relations quantity.
In step 303, if the quantity of mapping relations corresponding to same track link information exceedes predetermined value, then determine the corresponding new road net data of trace information without navigation data.
In the present embodiment, if the quantity of above-mentioned mapping relations exceedes this predetermined value, namely multiple navigational system all have recorded the trace information without navigation data on this section, then can think that this section is new section, i.e. the corresponding new road net data of this trace information without navigation data.
In some optional implementations, if the quantity of the mapping relations that same track link information is corresponding does not reach predetermined value, then can think may for the track drift caused due to the error of navigational system without the trace information of navigation data, the road that the section corresponding to it is not new.
Return Fig. 1, in step 105, if so, then the trace information without navigation data is processed, obtain, without the new road net data corresponding to the trace information of navigation data, adding in navigational route database, to upgrade navigation data.
After determining the corresponding new road net data of trace information without navigation data, need to process the trace information without navigation data, such as smoothing processing, to obtain accurate road net data.
Be understandable that, to new road net data, between the trace information that multiple navigational system records, certain deviation may be there is.The trace information 2031 without navigation data corresponding to same section such as obtained from multiple navigational system shown in Fig. 2,2032,2033, do not overlap mutually between 2034 and 2035.Further, not identical also may the causing between the data of multiple navigational system of positioning precision of navigation system produces deviation.
In some implementations, can process the trace information without navigation data in the following manner: determine that more than one navigational system corresponds to the trace information without navigation data in same section based on track link information; Intermediate value process or average value processing are carried out to the trace information without navigation data corresponding to same section.
In further realizing, can also by trace information filtering excessive for deviation before carrying out above-mentioned intermediate value process or average value processing, in order to avoid affect the degree of accuracy of road data.Like this, trace information can be reduced to positional information and the shape information of new road.
In other realize, can process the trace information without navigation data in the following manner: the corresponding geographic position of each data point on trace information, first at random the data point of a selected trace information is as the initial estimation of road data, adopts the method for iteration to revise the estimation of road data afterwards.Particularly, the data point of a trace information and the diversity factor of current estimation can be calculated, this diversity factor can be mean square deviation, standard deviation etc., revises, then calculate the diversity factor between next trace information and last time revised estimation in the current estimation that then this diversity factor is added to.After traveling through each trace information, the final estimation of this geographic position road net data point can be drawn.Alternatively, can also arrange the condition of convergence, all carry out successive ignition to each trace information, until iteration result convergence, i.e. enough hour of diversity factor, the data point iteration of current track information is complete, carries out the iteration of next trace information.After above-mentioned iterative processing is carried out to each data point, the new road net data of continuous print can be obtained.
Alternatively, after intermediate value or average value processing, can the smoothing filtering to the road net data obtained, to obtain level and smooth new road net data.Further, matching can also be carried out based on the continuity of road, draw more accurate new road net data.
In certain embodiments, can gather a large number of users historical track information in same section, the trace information based on big data quantity as above processes, and obtains new road net data, the position of reduction real road and shape.Afterwards, can new road net data be added in navigational route database, upgrade navigation data.
The navigation data disposal route that the present embodiment provides, by obtaining the trace information of navigation system records and in conjunction with the historical track of multiple user, can make new advances road net data.The method can realize Timeliness coverage and the renewal of road net data, effectively reduces the discovery cycle of new road net data.The method can also automatically upgrade road net data, considerably reduces the artificial time gathering new road net data, improves the efficiency of renewal.Further, the mode that the new road net data drawn relies on user feedback more completely has higher accuracy.
For above-described embodiment of the application, the scene of application can be: user drives to use in navigation procedure, and navigational system, can according to actual GPS location display driving trace once recognize without road network information.At this moment, navigational system can record driving trace and GPS information, user identification code CUID, driving trace and GPS information is sent in real time in navigation server.Navigation server can extract driving trace and GPS information by user identification code CUID, and determine the GPS information of two end points on the section without navigation data, the mapping relations between the GPS information setting up this section and two end points.This sections of road track that can return in conjunction with multiple navigational system afterwards judges whether there is new road in this track regions, if above-mentioned mapping relations number of times is greater than the threshold value of setting, then can judge to there is new road in this track regions.Afterwards the trace information of navigational system multiple in this region is done the smoothing processing such as average, namely can reduce the positional information of new road and shape information.
With further reference to Fig. 4, it illustrates the exemplary process diagram of the navigation data disposal route according to another embodiment of the application.
As shown in Figure 4, in step 401, the correlation time information of navigational system without navigation data is obtained.
In the present embodiment, navigational system can record information correlation time without navigation data in navigation procedure, i.e. the duration of car mark free state, and is stored the recorded duration or passback navigation server.Particularly, directly can record the time span that car mark free state continues, also time point without navigation data can be converted to from there being navigation data by registration of vehicle, and from being converted to the time point of navigation data without navigation data, calculate the duration of car mark free state afterwards according to two time points.Navigational system or navigation server can extract the temporal information without navigation data preserved by navigational system or send.
In step 402, judge correlation time, whether information met Preset Time condition.
In the present embodiment, whether the time span that can continue based on car mark free state meets Preset Time condition judges whether vehicle enters non-existent road in navigational system.This Preset Time condition can exceed preset time threshold for the temporal information without navigation data.The setting of preset time threshold can adopt the defining method identical with the predetermined value of mapping relations quantity in embodiment corresponding to above-mentioned Fig. 3.Namely training set and the test set of preset time threshold can be constructed based on the trace information of multiple navigational system and actual road net data, training set is adopted to train, determine the initial value of preset time threshold, based on test set, correction optimization is carried out to the initial value of preset time threshold afterwards, obtain the optimal value of preset time threshold.
If correlation time, information exceeded preset time threshold, when the car mark free state duration is longer, then can think that the road of current driving is new road.If correlation time, information did not exceed preset time threshold, then can think that the track that the error that current car mark free state is navigational system causes drifts about, the road of current driving is not new road.
In step 403, if so, trace information and the locating information of navigational system is obtained.
In the present embodiment, if meet Preset Time condition without the temporal information of navigation data, then can be obtained trace information and the locating information of navigational system by user identification code.Trace information can be the recorded information of driving path, can include the trace information of navigation data and the trace information without navigation data.Locating information can for the GPS information generated by navigational system.
In step 404, the trace information without navigation data in trace information is extracted.
In the present embodiment, by the trace information intercepting car mark free state, the trace information without navigation data can be extracted from the trace information that step 403 obtains.
In step 405, determine without the track link information corresponding to the trace information of navigation data based on locating information.

In a step 406, the whether corresponding new road net data of trace information without navigation data is judged according to track link information.
In the present embodiment, the trace information of obtained multiple navigational system can be traveled through, set up the mapping relations without navigation data trace information and track link information.And the quantity of the mapping relations in same actual section is corresponded to based on track link information statistics, when the quantity of mapping relations is more than a preset value, can determine that this actual section is new road, namely without the corresponding new road net data of trace information of navigation data.
In step 407, if so, then the trace information without navigation data is processed, obtain without the new road net data corresponding to the trace information of navigation data, add in navigational route database to upgrade navigation data.
After determining the corresponding new road net data of trace information without navigation data, can determine according to locating information the historical track information generated by multiple navigational system corresponding to this new road net data.To the smoothing process of historical track information, accurate new road net data can be generated, and adds in navigational route database, upgrade navigation data.
Step 403 in above-mentioned realization flow, step 404, step 405, step 406 and step 407 are identical with the step 101 in previous embodiment, step 102, step 103, step 104 and step 105 respectively, do not repeat them here.
In a step 408, obtain without the velocity information corresponding to the trace information of navigation data.
In the present embodiment, while the new road net data of calculating, vehicle speed information corresponding to new road net data can also be obtained by navigational system.Further, the velocity variations information of detailed vehicle can also be obtained, as the geographical location information, maximal rate etc. of acceleration/deceleration.In some implementations, the trace information duration without navigation data can be obtained, locating information based on the trace information without navigation data determines the length without the section corresponding to the trace information of navigation data, thus can obtain the average velocity in this section.
In step 409, determine without the speed-limiting messages corresponding to the trace information of navigation data based on velocity information.
After obtaining without the velocity information corresponding to the trace information of navigation data, in conjunction with the size of velocity information medium velocity and change, and can determine without the speed-limiting messages on the section corresponding to the trace information of navigation data according to locating information.Be appreciated that may there be multiple speed-limiting messages in a section.By being combined with velocity information by gps data, then can obtain the multiple speed-limiting messages on section.
