Please the various non-limiting implementations in embodiment illustrate.Obviously, described embodiment is the application one
Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
All other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.
Referring to Fig.2, Fig. 2 shows the flow diagram of the method for recognition and tracking vehicle a kind of in the embodiment of the present application, it should
Method can specifically include:
S201: acquisition target vehicle is overlapped path with front vehicle, wherein in the driving direction of target vehicle, after
Square vehicle is located at target vehicle rear.
It should be noted that may at least apply in the present embodiment in two kinds of application scenarios.Wherein, the first is exemplary
Application scenarios, can be as shown in Figure 1, be each step in the method for executed recognition and tracking vehicle by Cloud Server；Second
Exemplary application scene is that tracking vehicle is identified by target vehicle.In order to be more convenient for understanding the technology of the embodiment of the present application
Scheme, in the following, the technical solution of the embodiment of the present application is described in detail by taking the first exemplary application scene as an example.
The core idea of the present embodiment is, is determined using the registration of target vehicle and the driving path of front vehicle
Whether front vehicle is the vehicle for tracking target vehicle traveling, therefore, in order to calculate the registration, available target
The path that is overlapped of vehicle and front vehicle, i.e., front vehicle is run over target vehicle in the driving path of acquisition target vehicle
Path sections.
In practical application, due to not sending out molecule when tracking vehicle driving, the vehicle for being usually maintained tracked is located at not
In the range of visibility of method molecule, i.e., the vehicle of driving and tracked the distance between vehicle would generally be maintained at by criminal
In the range of visibility of criminal.Based on this, in a kind of illustrative embodiment, shooting can be installed on target vehicle
Device, the filming apparatus can shoot front vehicle, should if really there is front vehicle is tracking target vehicle
The front vehicle device that can usually be taken takes, then, can be taken by the filming apparatus in recognition and tracking vehicle
It is identified in front vehicle.
It is appreciated that since the vehicle for being located at target vehicle rear is usually more, it is obtained captured by filming apparatus
Front vehicle is usually more, is distinguished for the ease of Cloud Server to these front vehicles, can further be obtained each
The characteristic information of front vehicle, wherein this feature information can be used for being identified front vehicle.As an example, may be used
Using one such or much informations such as the color, shape, type, brand, the license plate numbers that obtain each front vehicle as should
The characteristic information of front vehicle.In a kind of illustrative embodiment, obtained in shooting comprising front vehicle in filming apparatus
Image or video after, the obtained image of shooting or video data can be sent to Cloud Server by target vehicle, be taken by cloud
Business device parses the characteristic information of front vehicle from the image or video data received, is parsed in order to utilize
Characteristic information is identified the front vehicle.
Also, Cloud Server is determining that there are rears at target vehicle rear from the image or video data received
When vehicle, available target vehicle is overlapped path with front vehicle.In a kind of illustrative specific implementation, cloud clothes
Business device can use the starting point that GPS positioning goes out between the target vehicle and front vehicle to be overlapped path, if Cloud Server continues
The front vehicle is identified from the image or video data that target vehicle is sent, then weight between target vehicle and front vehicle
The length of combining diameter is continuously increased.
S202: obtaining the driving path of target vehicle, and the starting point of the driving path is consistent with the starting point in path is overlapped.
In the present embodiment, in addition to need to obtain front vehicle and target vehicle be overlapped path other than, it is also necessary to obtain mesh
The driving path of vehicle is marked, in order to which the subsequent registration for carrying out driving path calculates.It should be noted that acquired target
The driving path of vehicle, not necessarily target vehicle from origin to destination where vehicle route, but in cloud service
Device parses the rear of target vehicle there are when front vehicle, where target vehicle at this time from image or video data
Position is starting point, the traveling road of target vehicle, that is, the starting point of the driving path of target vehicle and the starting point one for being overlapped path
It causes.
It is appreciated that when Cloud Server detects that there are front vehicles, and target vehicle to be followed to travel for the rear of target vehicle
When, only show that the front vehicle has the possibility of tracking target vehicle, at this point, just needing to pay close attention to whether the front vehicle is tracking
Vehicle, be based on this, be the position that will test where this moment target vehicle of front vehicle in the present embodiment, as target
The starting point of the driving path of vehicle, and on the driving path pay close attention to front vehicle follow the bus situation.If from discovery front vehicle
Start, front vehicle tracks always target vehicle traveling, then can determine that front vehicle is the vehicle for tracking target vehicle traveling.
S203: if the length of driving path reaches pre-set length threshold, the registration for being overlapped path and driving path is calculated.
S204: according to the registration, determine whether front vehicle tracks target vehicle.
In the present embodiment, needs the length of the driving path of target vehicle to reach pre-set length threshold, that is, need target carriage
In the position to find front vehicle as starting point, certain fare register is travelled, calculates the weight being overlapped between path and driving path
It is right with determine front vehicle whether be tracking vehicle.If the length of driving path reaches pre-set length threshold, it is overlapped path
It is higher with the registration of driving path, show that a possibility that front vehicle tracking target vehicle travels is larger, then after can determining
Square vehicle is tracking vehicle；If the length of driving path reaches pre-set length threshold, coincidence path is overlapped with driving path
It spends lower, then can determine that the front vehicle is not belonging to the vehicle that is travelled of tracking target vehicle.
It should be noted that after the acquisition the coincidence path of square vehicle-to-target vehicle when, can be according to target vehicle
Driving path determine be overlapped path.If specifically, Cloud Server continues the figure sent from target vehicle in certain time
As or Digital video resolution go out front vehicle, then can using the driving path of target vehicle in the period as front vehicle and
Coincidence path between target vehicle.If if being appreciated that, Cloud Server continues to send from target vehicle in certain time
Image or Digital video resolution go out front vehicle, show the front vehicle persistently follow during this period of time target vehicle into
Every trade is sailed, then the driving path of target vehicle is also the driving path of front vehicle, then can be by the target vehicle in this section
Driving path in period is overlapped path as between front vehicle and target vehicle.
Further, if front vehicle is during following target vehicle to travel, there are partial time periods not by target carriage
Filming apparatus taken by, in other words front vehicle disappear in the coverage of filming apparatus a period of time, in order to retouch
It states conveniently, referred to as first time period, then before Cloud Server may think that front vehicle does not follow in the first time period
Square vehicle, but in practical application, if the image that Cloud Server is shot from filming apparatus again after the first time period
Or the front vehicle is parsed in video, and target vehicle is in the driving path in first time period and there is no other
Optional road, then driving path of the front vehicle in first time period can be also overlapped with the driving path of target vehicle, this
When, for the driving path of target vehicle in first time period, can also be used as target vehicle and front vehicle is overlapped path.
In practical application, Cloud Server is if it is determined that front vehicle can then send out the definitive result in tracking target vehicle
Target vehicle is given, so that target vehicle carries out phase to the driver (car owner) of target vehicle based on the definitive result received
The prompt answered.For example, target vehicle can prompt driver: " rear license plate, which is that the black vehicle of XXXX is doubtful, to be tracked
This vehicle asks driver to pay attention to！"
It is noted that can be combined with other factors in addition to based on the registration for being overlapped path and driving path
Determine whether front vehicle tracks target vehicle.Such as when can be in conjunction with danger classes, the follow the bus of front vehicle of front vehicle
Between and target vehicle one or more in quantity of optional path etc. is judged when driving on driving path.Below
Each is directed to because usually explaining one by one.
The danger classes of front vehicle characterizes the degree of danger of front vehicle.Specifically, due in practical application,
Some vehicles may belong to illegal vehicle, such as, it may be possible to belong to the vehicle being tampered, fake-licensed car (refers to that criminal forges
Illegally extract the number plate of true board vehicle, the vehicle of model and color) etc., for this illegal vehicle, danger classes usually compared with
It is high.When this vehicle follows target vehicle to carry out when driving, the risk of vehicle tracking target vehicle traveling can also increase accordingly
Greatly.Therefore, in the front vehicle for detecting that target vehicle is followed to travel, the danger classes of the available front vehicle, and
In conjunction with the danger classes of the front vehicle and the registration in coincidence path and driving path, determine whether front vehicle is tracking
Vehicle.In a kind of illustrative embodiment, Cloud Server can determine rear vehicle based on the characteristic information of front vehicle
Danger classes, specifically can be the hazardous vehicles that will be stored in the characteristic information of front vehicle and hazardous vehicles register base
Characteristic information is matched, and matching result is obtained, and is based on the matching result, is determined the danger classes of front vehicle.For example, if
Successful match, it is determined that the danger classes of the front vehicle is height, if it fails to match, it is determined that the danger classes of front vehicle is
It is low, in further embodiment, finer division can be carried out to danger classes, be such as divided into it is low, lower, compared with
High, high four grades.Then, it can in conjunction with the danger classes for the front vehicle determined and coincidence path and traveling
The registration in path, to determine whether front vehicle tracks target vehicle.
Furthermore it is also possible to whether determine front vehicle in conjunction with the follow-up time of front vehicle and calculated registration
Track target vehicle.It is appreciated that if Cloud Server detect front vehicle last longer follow always target vehicle into
Every trade is sailed, then the front vehicle there are it is larger a possibility that track target vehicle.Therefore, in a kind of illustrative embodiment
In, the follow-up time that the available front vehicle of Cloud Server follows target vehicle to travel, and when the follow the bus of combination front vehicle
Between and be overlapped the registration between path and driving path to determine whether front vehicle tracks target vehicle.
Furthermore it is also possible to the quantity of optional path of the combining target vehicle on driving path when driving and be calculated
Registration determine whether front vehicle tracks target vehicle.It is appreciated that if what target vehicle travelled on driving path
In the process, there are multiple optional paths, i.e. front vehicle can choose traveling there are many path, at this point, if front vehicle
Travelled all along the driving path of target vehicle, then the front vehicle there are it is larger a possibility that tracking target carriage
?.In a kind of example, if the quantity of target vehicle optional path existing during travelling on driving path is more,
And front vehicle persistently follows target vehicle to travel, then a possibility that front vehicle tracking target vehicle, is also bigger；Conversely, if
The quantity of optional path is fewer, then also can be corresponding smaller a possibility that front vehicle tracking target vehicle.
It is worth noting that, in practical application, Cloud Server can be in conjunction with the danger classes of front vehicle, front vehicle
Follow-up time and target vehicle on driving path when driving any one in quantity of optional path etc. or it is multiple because
It is plain to determine whether front vehicle tracks target vehicle with calculated registration.As an example, big data can be used
The mode of analysis, using scoring, it is that tracking vehicle scores that be directed to each factor, which be front vehicle, is then calculated point
Several average value.If score average is more than certain threshold value, it is determined that front vehicle tracks target vehicle, if score average is low
In the threshold value, it is determined that front vehicle normally travel is not the vehicle of tracking target vehicle.
For example, the follow-up time when Cloud Server combination registration, the danger classes of front vehicle and front vehicle comes
When determining whether front vehicle tracks target vehicle, if path registration is 0.8, danger classes is high, follow-up time 0.2h
(hour), then can for be directed to path registration be front vehicle scoring be 80 points (full marks are 100 points), be directed to danger
Grade be front vehicle scoring be 100 points (full marks are 100 points), it is 60 points that be directed to follow-up time, which be front vehicle scoring, so
Calculate these three scores afterwards is equally divided into 80 points (calculating process is (80+100+60)/3), and this 80 points are higher than default point
Number threshold value 75 can then determine that the front vehicle tracks target vehicle, and then can carry out to the driver of target vehicle corresponding
Prompt.
In the present embodiment, degree is overlapped according to the path between front vehicle and target vehicle, to determine that front vehicle is
No tracking target vehicle, in order to which target vehicle can be prompted in time in the case where determining that front vehicle tracks target vehicle
Car owner, to protect the life privacy of target vehicle car owner and improve the personal safety of the car owner.Specifically, available
Target vehicle is overlapped path with front vehicle, wherein in the driving direction of target vehicle, front vehicle is located at target vehicle
Rear, also, the driving path of target vehicle is also obtained, the starting point of the driving path is consistent with the starting point in path is overlapped, if mesh
The length of driving path for marking vehicle reaches pre-set length threshold, then can calculate target vehicle and front vehicle is overlapped path
With the registration of the driving path of target vehicle, and according to the calculated registration of institute, to determine whether front vehicle tracks mesh
Mark vehicle.If being travelled since front vehicle tracks always target vehicle, then the road between front vehicle and target vehicle
Diameter registration would generally be higher, therefore, by calculating driving path between front vehicle and target vehicle in the present embodiment
Registration can determine whether front vehicle is to track the vehicle of target vehicle, and then determining rear based on the registration
When vehicle tracking target vehicle, timely the car owner for driving target vehicle can be prompted accordingly, so that car owner's energy
It is enough to find out to track the vehicle of traveling in time and take corresponding counter-measure, so as to effective protection target vehicle car owner's
Life privacy and the personal safety for improving the car owner.
It is worth noting that, being by taking Cloud Server recognition and tracking vehicle as an example in above-described embodiment to the embodiment of the present application
Technical solution describes in detail, can also be by target vehicle itself come recognition and tracking vehicle in practical application.At this point, with upper
Unlike stating in embodiment, target vehicle, can be direct after shooting to obtain image or video data using filming apparatus
The image or video data are parsed, and need that Cloud Server, the process of entire recognition and tracking vehicle will be sent to
It is to be completed by target vehicle, is not related to the interaction with Cloud Server.
