Description
Technical field
The present invention relates to vehicle monitoring field, especially a kind of method for judging vehicle and trans-regional behavior whether occurring.
Background technique
It, can be in order to being tracked to vehicle behavior, or convenient for being car owner by being monitored in real time to vehicle location
Service (such as the information near push positioning) is provided.
At present for the localization method of vehicle, mostly uses and vehicle is positioned based on GNSS device, it is low with vehicle sheet,
The characteristics of versatility is high, strong real-time.For vehicle driving track, for example whether the judgement across city behavior occurs, it is also based on
Which is calculated.But whether the judgment mode across city (region) behavior is occurred for vehicle at present, to judge that vehicle exists
Whether region locating for two time points is identical, if it is different, being then judged to that across city behavior occurs, this kind of mode is in vehicle
Judging result when the more internal situation in region is more accurate, still, for the vehicle of zone boundary traveling, since GNSS is set
There is the phenomenon that offset in standby positioning, then usually can the positioning (locating region) to vehicle judge by accident, in this way, for vehicle across
The judgement of city behavior, and the statistics of the frequency for vehicle across city behavior, will generate biggish error.
Summary of the invention
Goal of the invention of the invention is: in view of the above problems, providing a kind of certain position error model of tolerable
Across the city behavior judgment method of the vehicle enclosed, this method can effectively mitigate the position error of GNSS device to vehicle across city behavior
Influence degree, and then effectively improve the accuracy of behavior judgement across city to vehicle.
The technical solution adopted by the invention is as follows:
A method of judging whether vehicle occurs trans-regional behavior, comprising the following steps:
S1: building administrative region database, which includes each administrative region of several administrative regions
Area information, center of gravity information and adjacent administrative information region；
S2: the real-time positioning of vehicle is acquired；
S3: administrative region corresponding to the center of gravity nearest from vehicle location is calculated；
S4: judge vehicle location whether S3 calculated administrative region and the administrative region adjacent with the administrative region
In, if so, the number of states for being in the administrative region where its positioning to vehicle adds up, S5 is executed, otherwise, is executed
S2；
S5: judging whether vehicle reaches predetermined value corresponding to the number of states of its administrative region being in, if so, to corresponding
Administrative region is marked, and executes S6, otherwise, executes S2；
S6: in the judgement administrative region adjacent with the administrative region of current markers, if there are labeled administrative regions, if
It is then to determine vehicle there are trans-regional behaviors, otherwise, executes S2.
The region that vehicle may be in tentatively is judged with center of gravity, and then filters out the possible movable regional scope of vehicle, only
These ranges are monitored to judge the trans-regional behavior of vehicle.Further, the positioning for vehicle on region, using repeatedly fixed
The mode of point judgement (count and mark after reaching predetermined value), the region that accurate judgement vehicle is in can be effectively prevented because fixed
Position equipment drift causes the erroneous judgement of positioning, is particularly suitable for the location determination in zone boundary area.By based on to position error
The positioning method of filtering judges the trans-regional behavior of vehicle, can be in the case where monitoring less regional scope, by simple
Mode, obtain accurate judging result.
Further, method of the invention further include: the number of states for corresponding to each administrative region to vehicle resets
The step of.On the one hand memory space can be discharged by resetting, on the other hand can cause to avoid historical data to current behavior judgement
It influences.
Further, the step of above-mentioned number of states for corresponding to each administrative region to vehicle resets occurs described
Determine that there are after trans-regional behavior for vehicle in S6.After judging that across city behavior occurs for vehicle each time, this time judgement is remembered
The historical data of record is resetted, and can be re-started the step of subsequent behavior judges automatically, be avoided the interference of historical data.
Further, the reset are as follows: remove the label to vehicle institute spanning different districts.
The label to region is removed, can delete to the direct judgment basis across city behavior, i.e., will not discover on the one hand
Behavior is judged out, still, and will not delete the basic data of judgement, is carried out in this way, can travel behavior to the history of vehicle
Record, in case retrospect.
Further, above-mentioned S4 specifically:
From the calculated administrative region S3 and the administrative region adjacent with the administrative region, administrative region is chosen one by one；Needle
To the administrative region selected every time, executes location determination: vehicle location is judged whether in the administrative region, if so, right
The number of states that vehicle is in the administrative region adds up, and executes S5；Otherwise, an administrative region is chosen again execute positioning
Judgement；Until executing S2 when judging in vehicle location no longer any one administrative region chosen.
It, can be after by vehicle location to any region, that is, after carrying out by the way of being judged one by one each region
The continuous judgement across city behavior, without row judgement again after having traversed all areas.In this way, calculation amount can be saved effectively, mention
Computationally efficient.
Further, the S4 specifically:
It chooses the calculated administrative region S3 and executes S4-1；
S4-1: vehicle location is judged whether in the administrative region selected, if so, being in the shape of the administrative region to vehicle
State quantity adds up, and S5 is executed, otherwise, it is determined whether in the presence of mistake adjacent with the calculated administrative region S3, unselected
Administrative region, if so, execute S4-2 otherwise re-execute S2；
S4-2: selecting the administrative region of a mistake adjacent with the calculated administrative region S3, unselected, executes S4-1.
The corresponding region of calculated center of gravity is judged first, localization region judgement may be implemented, adjacent area is looked into
The parallel execution ask and sorted, meanwhile, the calculated region S3 directly can be directly used in calculating, without first determining traversal
Region.In this way, the calculation amount that traversal region determines can be saved effectively, while improving location determination efficiency.
Further, in the administrative region database of above-mentioned S1 building, the adjacent administrative region of each administrative region is believed
Breath is the index information of adjacent administrative region.
By storing index information, can accurately be found out adjacent in the case where the data volume very little of associated storage
Administrative region, effectively save data space reduce the complexity of database.
Further, in the S4, judge vehicle location whether in corresponding administrative region according to ray method.So-called phase
Whether the administrative region answered is judging vehicle location in the administrative region.
By the simple algorithm such as such as ray method, it can quickly determine vehicle location whether in corresponding region.
Further, the area information in above-mentioned S1 is latitude and longitude information or boundary information.
Latitude and longitude information acquisition modes are relatively easy, meanwhile, by latitude and longitude information it is available to other with position phase
The data of pass, and then multinomial parameter related with position can be obtained by calculating in the case where storing small amount data.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, by means of the invention it is also possible to avoid judging bring because of the drift of the positioning devices such as GNSS behavior across city to vehicle
It influences, the behavior especially for the movable vehicle in zone boundary location judges.
2, in the present invention, in vehicle location, the region of traversal is relatively small, and therefore, calculating data volume is small, computational efficiency
It is high.Further, by way of traversing one by one, it can quickly navigate to corresponding region and be judged, further improve meter
Calculate efficiency.Meanwhile the mode indexed by using storage region, it can quickly be searched in the case where storing very little data volume
To the area data needed to be traversed for.
3, the present invention clears up historical data in time, can be performed automatically and go next time after across city behavior judgement each time
For judgement, avoiding historical data bring influences, high degree of automation, and judging result is accurate.
