Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that the described embodiments are merely a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Refering to fig. 1, be first embodiment of the invention licence plate recognition method flow diagram, in the first embodiment,
This method comprises:
S1: the first license plate picture for currently driving into vehicle of inlet is shot, and local vehicle is carried out to the first license plate picture
Board identifies to obtain the first local recognition result.
Wherein, local Car license recognition is identified using front end hardware, and recognition speed is fast.
S2: if the first local recognition result is complete license plate number, by the first local recognition result and the first license plate
Local is stored in after picture is associated.
Wherein, complete license plate number indicates that currently driving into vehicle is to have board vehicle, and complete license plate number refers to number of license plate number
Number of codes and format meet preset rules, such as the license plate number of China, and river A12345 is just complete
License plate number.
S3: if the first local recognition result is incomplete license plate number, cloud license plate is carried out to the first license plate picture
Identification obtains the first cloud recognition result, and using the first cloud recognition result as the first local recognition result and the first license plate figure
Piece is associated.
Wherein, cloud Car license recognition is identified using cloud, and discrimination is high, it is believed that the result of cloud Car license recognition is most
Terminate fruit.Incomplete license plate number indicates the number quantity of license plate number and format meets preset rules, for example, river A1234 due to
It is incomplete license plate number, reason may be the license plate breakage of the vehicle or be blocked, then example as soon as having lacked a number
If the first local recognition result is blank, without any number, then being also incomplete license plate number, reason may be the vehicle
Be new car, there are no suspension license plate.Whatsoever situation, incomplete license plate number all indicate that the vehicle is unlicensed vehicle, relatively
, complete license plate number then indicates that the vehicle is to have board vehicle.
If it is local keep records of in there are no the record of the first license plate picture, using the first cloud recognition result as the
Local is stored in after one local recognition result and the first license plate picture are associated.
S4: the second license plate picture of the current outgoing vehicles in exit is shot, and local vehicle is carried out to the second license plate picture
Board identifies to obtain the second local recognition result.
S5: if the second local recognition result is incomplete license plate number, cloud license plate is carried out to the second license plate picture
Identification obtains the second cloud recognition result.
S6: if the second cloud recognition result is complete license plate number, search whether exist in locally keeping records of
Identical with the second cloud recognition result first local recognition result.
S7: if there is the identical with the second cloud recognition result first local recognition result, then to current outgoing vehicles
Carry out regular fee clearing.
Wherein, if local keeps records of middle presence the first local recognition result identical with the second cloud recognition result,
So show that the local Car license recognition of inlet accurately identifies, but the local license plate number wrong identification in exit, but go out
Cloud Car license recognition at mouthful accurately identifies again, thus the second cloud recognition result is mutually matched with the first local recognition result,
So as to according to the disbursement and sattlements such as the two corresponding time because usually carry out regular fee clearing.
