Abstract
A kind of method of parking exit Car license recognition automatic error-correcting, it is characterized in that：Car license recognition is carried out in Entrance, and the license plate number of Car license recognition mistake is corrected by checking, the license plate number that correction is related to is charged to and corrects car plate list, the license plate number that need not be corrected and the correct license plate number obtained after correction are charged into current parking list, Car license recognition automatic error-correcting is carried out in parking exit.In fact, the car plate that Car license recognition is directed to, is often same car plate in Entrance and outlet.Car license recognition being carried out in Entrance mistake occurring, same identification mistake can also occur in the Car license recognition of parking exit.Therefore, the wrong license plate number for needing to correct will occur to distinguish with checking correct license plate number, and for the fuzzy matching that wrong license plate number is carried out in parking exit, with existing Car license recognition without any differentiation, the identification erroneous association of the identification mistake and parking exit of Entrance, the present invention do not had into obvious technological innovation.
Description
Technical field
The present invention relates to vehicle management technology, the vehicle management technology of internet is based especially on.
Background technology
At present, parking lot generally carries out parking lot vehicle management using Car license recognition.
The main problem of Car license recognition be it is easy Car license recognition mistake occurs, especially illumination, car plate are stained situations such as
Lower Car license recognition mistake is easier to occur.《A kind of parking lot based entirely on Car license recognition parking charging method》
（CN103456048A）Disclose by the identification to car plate before and after vehicle to ensure the correct method of Car license recognition.This method is led to
Cross to front and rear license plate recognition result review ensure that it is correct to the Car license recognition for driving into the vehicle in parking lot in Entrance.And
In parking exit, Car license recognition mode is equally taken to identify the car plate for preparing outgoing vehicles, mistake easily occurs for Car license recognition
The problem of still exist.After the deficiency of this method is considered, a kind of improved method for this method, i.e.《A kind of parking exit
Based entirely on the parking charging method of Car license recognition》（CN104599334A）Disclose and also take front and rear car plate in parking exit
Identification, and mistake is easily occurred solving Car license recognition again to the matched method of front and rear license plate recognition result by increase and is asked
Topic.
It can be seen from the above that Car license recognition mistake is the FAQs that parking lot carries out vehicle management.
The content of the invention
Mistake also easily occurs for the Car license recognition of parking exit, the present invention is right《A kind of complete base of parking exit
In the parking charging method of Car license recognition》（CN104599334A）Improved.
The technical solution used in the present invention is：
A kind of method of parking exit Car license recognition automatic error-correcting, it is characterized in that：Car license recognition is carried out in Entrance, and
The license plate number of Car license recognition mistake is corrected by checking, the license plate number that correction is related to is charged to and corrects car plate list, will
Current parking list is charged to without the license plate number corrected and the correct license plate number obtained after correction, car plate is carried out in parking exit
Identify automatic error-correcting；Described to carry out Car license recognition automatic error-correcting in parking exit, step is：
（1）, parking exit by camera obtain license plate image, carry out Car license recognition, obtain license plate recognition result；
（2）, by the license plate recognition result currently parking list in search, if matched record, then let pass after charging,
Otherwise next step is continued；
（3）, by the license plate recognition result and correct each record of car plate list and carry out fuzzy matching, if matched note
Record, then let pass after charging, otherwise continue next step；
（4）, turn abnormality processing.
It is described to be corrected the license plate number of Car license recognition mistake by checking, the license plate number that correction is related to is charged into correction
Car plate list, refers to and is further added by Car license recognition after the Car license recognition of license plate number is obtained, by increase Car license recognition obtain it is another
License plate number, two license plate numbers are compared, and are charged to one of them when two license plate numbers compare inconsistent and are corrected car plate list, or by two
A license plate number, which is all charged to, corrects car plate list, or inputs new license plate number in car plate list is corrected by manual method.
The fuzzy matching, refers to all characters of license plate number, and the character in addition to the character of specified digit all should be identical,
Specify the character of digit can be in the diverse location of license plate number.The specified digit, can be 1, or 2, or 3, selection
Whether the how many foundation of digit is to cause the record of " character in addition to the character of specified digit all should be identical " unique.This hair
It is bright to require uniquely, so just accomplish automatic error-correcting.If not unique, fuzzy matching is invalid, it is impossible to is matched accordingly
To corresponding as a result, also just not reaching the purpose of automatic error-correcting.
The abnormality processing can be artificial treatment, or exempts from charging and directly let pass.
In fact, the car plate that Car license recognition is directed to, is often same car plate in Entrance and outlet.Enter in parking lot
Mouth carries out Car license recognition and mistake occurs, and same identification mistake can also occur in the Car license recognition of parking exit.Therefore, will send out
The license plate number that raw mistake needs to correct is distinguished with checking correct license plate number, and for mistake license plate number parking exit into
Capable fuzzy matching, with existing Car license recognition without any differentiation, the identification mistake of Entrance is not gone out with parking lot
The identification erroneous association of mouth, the present invention have obvious technological innovation.
The method have the benefit that：
1st, overcome《A kind of parking exit based entirely on Car license recognition parking charging method》（CN104599334A）Stopping
Manual review is needed when Car license recognition mismatches before and after the outlet of parking lot, it is impossible to accomplishes the deficiency checked automatically.
2nd, fuzzy matching is directed to correct car plate list, is not or not for current parking list, benefit：On the one hand reduce
Calculation amount, improves computational efficiency；On the other hand, it is often more important that, " by checking the license plate number of Car license recognition mistake
Corrected " after, in parking exit for the license plate number not being repaired, fuzzy matching does not occur fuzzy with these license plate numbers
Matching, will not cause to be reviewed in Entrance and be interfered for correct license plate number.
3rd, the manual intervention of parking exit is reduced, improve parking exit rolls efficiency away from.
Embodiment
Even if one specific embodiment of the elaboration of technical solution of the present invention.
It should be noted that there may be the record not matched after fuzzy matching, this needs periodically match residual
The cleaning of remaining record.This is that those skilled in the art are readily apparent that, is repeated without inventor, i.e. any remaining record of increase
Cleaning mechanism, the claim of inventor is not limited in any way.
