Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.
The embodiment of the present disclosure provides a kind of track data compensation process, as shown in Figure 1, the compensation process includes following step
It is rapid:
101, user's history track is obtained.
User's history track includes user's starting point, user's terminal and at least one tracing point.
102, traversal history track database, when historical trajectory data and user's history track have consistent starting point and end
When point, it is determined as target trajectory data.
In an alternative embodiment, further include before traversal history track database,
Obtain the corresponding road condition data of running data;
According to running data and road condition data, historical trajectory data library is generated.
The historical trajectory data library of the disclosure is that the track data really run over according to user generates, and can further be mentioned
The authenticity of track data after high supplement, at the same the historical trajectory data library further include road condition data in user's driving process,
The related data of the influences such as weather data traveling, when obtaining the track data after supplement, can also synchronize acquisition influences user
The related data of traveling, driving path planning when going on a journey for user next time provides reference data, and then also improves use
The reliability when path planning of family.
103, according to user's history track and preset range, at least one reference locus point of target trajectory data really
At least one fixed object reference tracing point.
In an alternative embodiment, according to reference locus point at a distance from user's history track and quantity, dispersed parameters are set,
Preset rules are generated according to dispersed parameters.
In an alternative embodiment, it realizes when at least one reference locus point is determined as object reference track within a preset range
The method of point, including,
At least one reference locus point is compared point by point at least one user's history tracing point, determination deviation value;
According to deviation and preset range, determine whether at least one reference locus point is object reference tracing point.
Specifically, i.e., two tracing points to include in user's history tracing point, tracing point A, tracing point B, composition
On the basis of one track C, respectively with other from tracing point A to the track of tracing point B at least one reference locus point, carry out
It is point-by-point to compare and judged according to preset range.If tracing point meets preset rules, i.e. reference point is deviateing in range, then
Using the reference point as target trajectory reference point to supplement user's history track;If tracing point does not meet preset rules, i.e.,
Deviate outside range, then deletes the tracing point.
104, rail and user's history track are referred to according at least one target trajectory, generates target user's historical track.
In an alternative embodiment, it realizes after synthesizing at least one target trajectory with ownership goal track with reference to rail, generates
The method of target user's historical track, comprising:
When at least one reference locus point meet preset rules and it is non-coincidence with user's history tracing point when, determine at least one
A reference locus point is object reference tracing point;
According to object reference tracing point and user's history track, it is sequentially connected user's history tracing point and object reference track
Point generates target user's historical track.
It is illustrated in the following, enumerating specific example, rail and user's history track is referred to according at least one target trajectory, it is raw
At the method for target user's historical track:
By taking user's history track includes starting point A, tracing point B, terminal C as an example.
According to historical user's running data first among starting point A, tracing point B, reference locus point D is obtained, with reference to rail
Mark point E, reference locus point F, reference locus point G;
According to preset rules, determine that reference locus point F is intended reference point;
It is sequentially connected starting point A, reference locus point F, tracing point B, terminal C and generates target histories route of user.
In an alternative embodiment, after generating target user's historical track, further include
Label generates target user's historical track and is transmitted to historical track library;
When obtaining historical trajectory data library, target user's historical track or user's history rail can be obtained by label, selection
Mark.
In a particular embodiment, after generating target and generating mesh user's history track, label generates target and uses the disclosure
Family historical track is with reference to route, and user's history track does not make marks, and is transmitted to historical track library;When user passes through this public affairs
It opens after obtaining historical trajectory data, is selected by the label, check user's history track and target user's history rail respectively
Mark, it can check respectively, the original historical track of user and the user's history track supplemented are gone through to further increase user
The authenticity of history track data and the property of can refer to.
The track data compensation process that the embodiment of the present disclosure provides, this method is by obtaining the track in user's history track
Point information, traversal history running data library determines object reference tracing point according to preset rules, and object reference tracing point is mended
It is charged to user's history track data, generates target user's historical trajectory data, to realize to the supplement of user's history track
Reason.
The target trajectory data that the disclosure is determined by preset rules and user's history track, can guarantee the target of screening
Track data is matched with the curve similarity of user's history track;To guarantee the object reference screened in target trajectory data
The authenticity of tracing point and high matching degree can be avoided user's history track data by supplementary target reference locus point because of rail
The deviation that mark point data missing occurs improves the smoothness of user's history track number after supplement, after further guaranteeing supplement
The authenticity of track data.Such as, when driving trace passes through corner location, user's history track causes because tracing point lacks
The track data of true broken line shape becomes the track of rectilinear form.
Target user's historical track that the disclosure provides is supplemented based on the true driving trace data of historical user
Processing, therefore, can be avoided in the prior art based on the data in map datum it is imperfect caused by data error, such as in city
Road data etc. is also marked not in time without region newly developed in mark road data or city outside city.
