Picture can also have photo to have video data again, and the image obtained herein is filled by being set to the image collection of sentry box cash desk
It puts and collects.
Step 102：According to the image data got and/or the characteristic information of vehicle got from server end to vehicle
It is identified.
In the present embodiment, it when vehicle is identified, can be identified by the unique mark to vehicle, so that
Vehicle is identified with the unique mark of vehicle, exemplary, which can be license plate number.But it is identified to vehicle
When, it is possible to the vehicle that None- identified is identified to license plate number or currently is at all just without car plate, in that case, such as Fig. 2
Shown, the vehicle identification method of the present embodiment includes：
Step 201：When vehicle drives into or is driven out to parking lot, the image data of vehicle is obtained；
Step 202：In the case of the unique mark of the image data acquisition according to vehicle to vehicle, unique mark is used
Identify vehicle；
Step 203：In the case where the image data according to vehicle can not obtain the unique mark of vehicle, from server end
The characteristic information of vehicle is obtained, vehicle is identified according to characteristic information.
Wherein, characteristic information is identified to obtain by server to image data.
In the present embodiment, the image collecting device of sentry box cash desk is set to after the image data of vehicle is collected,
The image collected data are sent to server end.Server end may be used GPU accelerate calculate mode come to image into
Row identification.
Optionally, features described above information can include the number-plate number, vehicle body characteristics of image, body color, vehicle style with
And at least one of vehicle model.
When carrying out Car park payment to vehicle, the unique mark according to vehicle is needed to obtain vehicle parking details, is based on
This, vehicle identification method provided in this embodiment can also include：When vehicle of leaving the theatre is identified, vehicle of leaving the theatre is used
Characteristic information is matched with the characteristic information of admission vehicle, and information is recorded to obtain the parking for vehicle of leaving the theatre；Remembered according to parking
Record information calculates the Parking Fee for vehicle of leaving the theatre.Wherein, using the characteristic information for vehicle of leaving the theatre and the characteristic information of admission vehicle
Carrying out matched operation can specifically include：Characteristic information using the characteristic information and admission vehicle of vehicle of leaving the theatre is compared
It is right, the admission vehicle that there are at least three consistent features information with vehicle of leaving the theatre is confirmed as vehicle of leaving the theatre.
Fig. 3 is the flow chart of another vehicle identification method of the present embodiment, Fig. 3 show vehicle from enter parking lot to
Involved vehicle identification process during the entire process of parking lot is left, as shown in figure 3, this method includes following processing：
Vehicle enters sentry box charge entrance departure place sense, and vehicle checker exports switching information, is set to the figure of sentry box cash desk
Picture harvester carries out Image Acquisition to vehicle, and by the image collected information reporting to GPU server ends, which includes more
The image information of frame license plate image information and vehicle, the image information that GPU server-sides are reported to receiving image collecting device
Deep learning and identification are carried out, after server end identifies current vehicle, exports and opens a sluice gate signal to image collecting device, figure
As harvester outputs signal to banister, banister is opened after receiving signal.
Vehicle identification method provided in this embodiment, what the number-plate number was identified in the integrated camera in sentry box cash desk
