Embodiment 1

A kind of vehicle identification method is present embodiments provided, as shown in figure 1, comprising the following steps：

S1. the first information and physics car plate bag that the electronic license plate of the same vehicle of some inspection bayonet socket collection is included are judged Whether the second information contained matches, if matching, judges the vehicle for legal vehicle.In concrete application, inspection bayonet socket is installed on Electronic license plate reading device and pattern recognition device, which are in, persistently checks state, gathers the electronic license plate bag of the vehicle of each process The second information that the first information and physics car plate contained is included.In order to ensure collect that the electronic license plate of same vehicle is included The second information that one information and physics car plate are included, can obtain one or more vehicle in the range of sometime time threshold Information of vehicles, the second information that the first information and physics car plate that the electronic license plate that information of vehicles includes vehicle is included are included, the One information and the second information include the number-plate number and vehicle appearance information (such as vehicle color, vehicle, brand of correspondence vehicle Etc. information).Equipment (such as electronic license plate reading machine) is read for reading the electronic license plate of electronic license plate information and for gathering The triggering and identification of the image recognition apparatus (such as camera) of physics license plate image information, the principle read are different, therefore The time for obtaining the first information is not consistent with the time for obtaining the second information, there is time delay, and certain is only obtained for the moment by regulation Between in the range of (determine) that the information of vehicles of one or more vehicle (is possible to the time model according to the time delay of two equipment rooms There are many cars to pass through from the bayonet socket in enclosing, multiple information of vehicles will be collected, generally only one car process), energy Information of vehicles is in same time delay range, the first information of same car is ensure that while drawdown ratio is to scope It can be got with the second information, be conducive to the later stage to be used for the integrality for the data that information of vehicles is matched.The above-mentioned number-plate number The radio frequency electric chip in electronic license plate can be stored in vehicle appearance information, can just be read by electronic license plate reading machine Arrive, and based on this acquisition first information；By analyzing vehicle appearance image and physics license plate image that image recognition apparatus is gathered, The above-mentioned number-plate number and vehicle appearance information can also be got, and based on this second information of acquisition.

If S2. mismatching, according to the vehicle running path, what the acquisition multiple bayonet sockets adjoining with inspection bayonet socket were gathered should The second information that the first information and physics car plate that the electronic license plate of vehicle is included are included.In concrete application, vehicle running path The historical record travelled according to vehicle can be obtained.Adjoining bayonet socket can be the vehicle traveling centered on the inspection bayonet socket Upstream bayonet socket and vehicle before to the inspection bayonet socket will travel downstream bayonet socket extremely after the inspection bayonet socket, or Along vehicle running path after the inspection bayonet socket according to order from the close-by examples to those far off will by way of more than two bayonet sockets.Specific bayonet socket Selection can determine according to actual needs.

Preferably, as shown in Fig. 2 step S2 includes：

S21. determine that vehicle is travelled to the upstream bayonet socket and vehicle before inspection bayonet socket through checking according to vehicle running path The downstream bayonet socket that travel extremely is looked into after bayonet socket.In concrete application, according to the bayonet socket position set in traffic zone and vehicle Driving path is lockable upstream bayonet socket and estimates out the position of downstream bayonet socket, very convenient.

S22. average speed, inspection bayonet socket and the upstream bayonet socket travelled according to the current recognition time of inspection bayonet socket, vehicle Distance between the bayonet socket of downstream obtains vehicle by the first time point and vehicle during the bayonet socket of upstream by during the bayonet socket of downstream Second time point.In concrete application, the current recognition time of inspection bayonet socket is time of the vehicle by way of the inspection bayonet socket (Tc), the average speed of vehicle traveling can be estimated by image recognition technology, inspection bayonet socket and upstream bayonet socket and downstream card Distance between mouthful can be obtained according to the bayonet socket position set in the traffic zone being previously stored.Vehicle by upstream bayonet socket travel to Check the time t needed for bayonet socket₁Distance/average speed between=upstream bayonet socket and inspection bayonet socket, vehicle is travelled by inspection bayonet socket To the time t needed for the bayonet socket of downstream₂Distance/average speed between=inspection bayonet socket and downstream bayonet socket, is understood, the very first time with this Point is Tc-t₁, the second time point was Tc-t₂.Pass through first time point and the second time point, it may be determined that the vehicle is by way of upstream Upstream bayonet socket, inspection bayonet socket and downstream bayonet socket are collected in the time window of bayonet socket, inspection bayonet socket and downstream bayonet socket, the time window The second information that the first information and physics car plate that will necessarily be included in data including the electronic license plate of the vehicle are included, in contracting The later stage is conducive to be used for the integrality of data of vehicle identification while small comparison scope.

S23. the electronics of the vehicle that upstream bayonet socket is gathered in the range of the time threshold centered on first time point is obtained The second information that the first information and physics car plate that car plate is included are included, obtains the time threshold model centered on the second time point Enclose the second information that the first information and physics car plate that the electronic license plate of the vehicle of interior downstream bayonet socket collection includes are included.Specifically In, the determination principle of above-mentioned time threshold scope with checked in step S1 the bayonet socket collection first information and the second information when Between threshold value determination principle it is similar, be all according between electronic license plate identifying device and image recognition apparatus obtain information time difference To determine, typically take 5 minutes.Each bayonet socket can be made to collect the first information and the second information of same car, it is ensured that The integralities of data.

S3. judge whether the first information and the second information of each bayonet socket collection match, if mismatching, judge that the vehicle is Illegal vehicle.If matching, illustrates that fore-aft vehicle information matches result has contradiction, vehicle is suspect vehicle, can set one Individual ratio, such as have chosen the comparison result of three bayonet sockets, if there is two matching results to be that vehicle is legal vehicle, only one of which Matching result is that vehicle is illegal vehicle, then can be defined by the judged result of most of bayonet sockets, it is believed that the vehicle is legal car , the car record of crossing that suspect vehicle also can be manually transferred if necessary carries out artificial cognition.When external environment badly causes what is obtained The identification of second information is unclear, when the first information can not be with the second information matches, can be adjoining with inspection bayonet socket by judging Whether the first information and the second information of the same vehicle of bayonet socket collection match to verify above-mentioned judged result, it is to avoid The erroneous judgement situation of the unclear appearance of physics Car license recognition is likely due to during vehicle identification.

Preferably, as shown in figure 3, judging that the first information and the second information are in step S1 and step S3 as follows No matching：

S11. the second information being consistent with some first information is determined whether.In concrete application, if only collecting one The first information of individual vehicle and the second information, only the first information and the second information need to be compared, and judge what both included Whether the number-plate number is completely the same just can be with if unanimously, illustrate that the first information is consistent with the second information.But setting when Between in the range of may there are many cars to pass through from the bayonet socket, the information of vehicles of multiple vehicles is collected, at this time, it may be necessary to judge each the Whether one information has the second information being consistent with it, and the information of vehicles of many cars is matched, and realizes many of information of vehicles To many matchings.

If S12. there is the second information being consistent with the first information, the information of vehicles of vehicle corresponding to the first information is judged The match is successful.The first information and the data that the second information is collection in same time delay range, if having what is included with the first information The second completely the same information of the number-plate number, illustrates that the electronic license plate of same car is matched completely with physics car plate, namely matching The match is successful for the information of vehicles of the corresponding vehicle of the successful first information, and the illegal activities, monitoring efficiency such as deck are not present in vehicle It is high.

If the second information not S13. being consistent with the first information, to not matched in the first information and information of vehicles Successful second information carries out fuzzy matching.When external environment severe (situations such as strong light, misty rain, inadequate illuminance) or physics Car plate is defaced, causing physics Car license recognition situations such as block, unclear (the second information that the physics car plate of acquisition is included is forbidden Really), can also be to not matched into the first information and information of vehicles when can not precisely be matched down to the first information and the second information Second information of work(carries out fuzzy matching to veritify whether the corresponding information of vehicles of the first information matches, and is missed in physics car plate During the situation of identification, the second information can still be corrected by way of fuzzy matching, improve information of vehicles matching and sentence Disconnected success rate.

Preferably, as shown in figure 4, carrying out fuzzy matching in step S13 as follows：

S131. the second information for comparison is selected in the second information that never the match is successful.Preferably, step S131 Including：

S1311. the confidence level for each second information that the match is successful is obtained.In concrete application, existing skill can be selected Any one confidence calculations method in art obtains the confidence level for each second information that the match is successful.

S1312. the second minimum information of confidence level is therefrom selected as the second information for comparison.Choose confidence level The second minimum information can be eliminated in the second information that never the match is successful in time and put as the second information for comparison Reliability is low, interference is big, the second information not easy to identify, improves the efficiency of fuzzy matching.

S132. judge in the number-plate number that is included in the second information for comparison whether identification number in distress, hardly possible identification Number is in physics license plate image identification process, and because external environment is severe etc., reason is difficult to the number recognized, the mistake of the number Difference is larger, it is possible to exactly because the identification error of difficult identification number can just cause the first information and the second information can not be accurate Match somebody with somebody, it is thus determined that difficult identification number is significant to fuzzy matching, if forgoing hardly possible identification number, it is most likely that compared Accurate information of vehicles matching result.If identification number in distress, into step S133, if number is recognized without hardly possible, into step S135.Preferably, step S132 includes：

S1321. the confidence level of each number in the number-plate number included in the second information for comparison is obtained.Specifically should In, any one the confidence calculations method in the prior art that can choose obtains what is included in the second information for comparison The confidence level of each number in the number-plate number.

S1322. judge whether that confidence level is less than the number of preset number confidence level.By by the confidence level of number with Preset number confidence level compares, it is easy to it is determined that difficult identification number.

If S1323. in the presence of the number using confidence level less than preset number confidence level is used as hardly possible identification number.Confidence level It is low, illustrate the with a low credibility of the Number Reorganization, if less than the confidence level of preset number, illustrating that physics license plate image was recognized Cheng Zhong, the identification error of the number is larger, i.e., difficult identification number code.

S133. judge that the number of other positions in the number-plate number in addition to difficult identification number is corresponding with the first information Whether the number of position is consistent.The first information and the second information is caused not to match precisely containing difficult identification number in the second packet When, the fuzzy matching to the first information and the second information is realized by the default difficult number that recognizes, information of vehicles matching is improved The success rate of judgement.If being consistent, into step S134, if not being consistent, into step S135.
