Embodiment 1
Present embodiments provide a kind of vehicle identification method, as shown in Figure 1, comprise the steps:
S1. judge whether the first information that the electronic license plate of the same vehicle of certain inspection bayonet socket collection comprises and the second information that physics car plate comprises mate, if coupling, judge that this vehicle is legal vehicle.In embody rule, the electronic license plate reading device and the pattern recognition device that are installed on inspection bayonet socket are in lasting inspection state, the first information that the electronic license plate gathering the vehicle of each process comprises and the second information that physics car plate comprises.The second information that the first information comprised in order to ensure the electronic license plate collecting same vehicle and physics car plate comprise, the information of vehicles of one or more vehicle within the scope of time threshold sometime can be obtained, the first information that the electronic license plate that information of vehicles comprises vehicle comprises and the second information that physics car plate comprises, the first information and the second information comprise the number-plate number and the vehicle appearance information (information such as such as vehicle color, vehicle, brand) of corresponding vehicle.For read electronic license plate information electronic license plate fetch equipment (such as electronic license plate reading machine) and for the triggering of the image recognition apparatus (such as camera) that gathers physics license plate image information and identification, the principle read is different, therefore the time obtaining the first information is inconsistent with time of second information of acquisition, there is time delay, the information of vehicles only being obtained (time delay according to two equipment rooms is determined) one or more vehicle in scope sometime by regulation (likely has many cars to pass through from this bayonet socket in this time range, multiple information of vehicles will be collected, a car is generally only had to pass through), information of vehicles can be made to be in same time delay range, while drawdown ratio is to scope, ensure that the first information and second information of same car can both get, be conducive to the integrality of the data that the later stage mates for information of vehicles.The above-mentioned number-plate number and vehicle appearance information can be stored in the radio frequency electric chip in electronic license plate, just can be read by electronic license plate reading machine, and obtain the first information based on this; By analyzing vehicle appearance image and the physics license plate image of image recognition apparatus collection, also can get the above-mentioned number-plate number and vehicle appearance information, and obtaining the second information based on this.
If S2. do not mate, according to this vehicle running path, the first information that the electronic license plate obtaining this vehicle of the multiple bayonet socket collections adjoining with inspection bayonet socket comprises and the second information that physics car plate comprises.In embody rule, the historical record that vehicle running path travels according to vehicle can obtain.Adjoining bayonet socket can will travel downstream bayonet socket extremely for the vehicle centered by this inspection bayonet socket travels to the upstream bayonet socket before this inspection bayonet socket and vehicle after this inspection bayonet socket, also can be along vehicle running path after this inspection bayonet socket according to order from the close-by examples to those far off will by way of plural bayonet socket.Choosing of concrete bayonet socket can be determined according to actual needs.
Preferably, as shown in Figure 2, step S2 comprises:
S21. travel to the upstream bayonet socket before inspection bayonet socket and vehicle according to vehicle running path determination vehicle and will travel downstream bayonet socket extremely after inspection bayonet socket.In embody rule, estimate out the position of downstream bayonet socket according to the bayonet socket position arranged in traffic zone and vehicle running path and lockable upstream bayonet socket, very convenient.
S22. the average velocity, inspection bayonet socket and the distance between upstream bayonet socket and downstream bayonet socket that travel according to the inspection current recognition time of bayonet socket, vehicle obtains vehicle through the very first time of upstream bayonet socket put and vehicle through the second time point of downstream bayonet socket.In embody rule, the current recognition time of inspection bayonet socket is the time (Tc) of this vehicle by way of this inspection bayonet socket, the average velocity that vehicle travels can be estimated by image recognition technology, and inspection bayonet socket and the distance between upstream bayonet socket and downstream bayonet socket can obtain according to the bayonet socket position arranged in the traffic zone stored in advance.Vehicle is travelled to the time t needed for inspection bayonet socket by upstream bayonet socket 1distance/average velocity between=upstream bayonet socket and inspection bayonet socket, vehicle travels to the time t needed for the bayonet socket of downstream by checking bayonet socket 2distance/average velocity between=inspection bayonet socket and downstream bayonet socket, known with this, very first time point is Tc-t 1, the second time point is Tc-t 2.By very first time point and the second time point, the time window of this vehicle by way of upstream bayonet socket, inspection bayonet socket and downstream bayonet socket can be determined, the first information that the electronic license plate that will inevitably comprise this vehicle in the data that in this time window, upstream bayonet socket, inspection bayonet socket and downstream bayonet socket collect comprises and the second information that physics car plate comprises, be conducive to the integrality of later stage for the data of vehicle identification while drawdown ratio is to scope.
S23. the first information that the electronic license plate obtaining this vehicle of upstream bayonet socket collection within the scope of the time threshold centered by very first time point comprises and the second information, the first information that the electronic license plate obtaining this vehicle of bayonet socket collection in downstream within the scope of the time threshold centered by the second time point comprises and the second information that physics car plate comprises that physics car plate comprises.In embody rule, the determination principle of above-mentioned time threshold scope is similar with the determination principle of the time threshold of the second information with checking the bayonet socket collection first information in step S1, be all determine according to the mistiming of obtaining information between electronic license plate recognition device and image recognition apparatus, generally get 5 minutes.Each bayonet socket can be made all to collect the first information and second information of same car, ensure that the integrality of data.
S3. judge whether the first information and second information of each bayonet socket collection mate, if do not mate, judge that this vehicle is illegal vehicle.If coupling, then illustrate that fore-aft vehicle information matches result exists contradiction, vehicle is suspect vehicle, a ratio can be set, such as have chosen the comparison result of three bayonet sockets, if having two matching results to be vehicle is legal vehicle, only having a matching result to be vehicle is illegal vehicle, then can be as the criterion with the judged result of most of bayonet socket, think that this vehicle is legal vehicle, the car record of crossing also manually can transferring suspect vehicle if desired carries out artificial cognition.When external environment badly causes the second information identification of acquisition unclear, the first information cannot with the second information matches time, whether can be mated by the first information and the second information judging the same vehicle of the bayonet socket collection adjoining with inspection bayonet socket and above-mentioned judged result is verified, avoid in vehicle identification process likely due to the erroneous judgement situation of the unclear appearance of physics Car license recognition.
Preferably, as shown in Figure 3, judge in step S1 and step S3 whether the first information and the second information mate as follows:
S11. the second information conformed to certain first information is judged whether.In embody rule, if only collect the first information and second information of a vehicle, only this first information and the second information need be compared, whether the number-plate number that both judgements comprise is completely the same just passable, if consistent, illustrate that the first information conforms to the second information.But many cars may be had to pass through from this bayonet socket in the time range of setting, collect the information of vehicles of multiple vehicle, now, need to judge whether each first information has the second information conformed to it, the information of vehicles of many cars is mated, achieves the multi-to-multi coupling of information of vehicles.
If S12. there is the second information conformed to this first information, the match is successful to judge the information of vehicles of vehicle corresponding to this first information.The first information and the second information are the data gathered in same time delay range, if there is on all four second information of the number-plate number comprised with the first information, illustrate that the electronic license plate of same car mates completely with physics car plate, the match is successful for the information of vehicles of the vehicle that the first information that also namely the match is successful is corresponding, there are not the illegal activities such as deck in vehicle, monitoring efficiency is high.
If the second information S13. do not conformed to this first information, then carry out fuzzy matching to the second information that in this first information and information of vehicles, the match is successful.When the severe (high light of external environment, misty rain, the situations such as illuminance is inadequate) or physics car plate stained, the situation such as to block causes physics Car license recognition unclear (the second information that the physics car plate of acquisition comprises is inaccurate), so that when the first information and the second information can not precisely be mated, fuzzy matching can also be carried out whether mate to veritify information of vehicles corresponding to the first information the second information that in the first information and information of vehicles, the match is successful, when there is situation about identifying in physics car plate by mistake, still can by the mode of fuzzy matching, second information is corrected, improve the success ratio of information of vehicles matching judgment.
Preferably, as shown in Figure 4, fuzzy matching is carried out as follows in step S13:
S131. the second information for comparison is selected in the second information that never the match is successful.Preferably, step S131 comprises:
S1311. the degree of confidence of each second information that the match is successful is obtained.In embody rule, any one confidence calculations method of the prior art can be selected to obtain the degree of confidence of each second information that the match is successful.
S1312. the second minimum information of degree of confidence is therefrom selected as the second information for comparison.Choose the second minimum information of degree of confidence as the second information for comparison, can eliminate that degree of confidence is low in the second information that never the match is successful in time, interference greatly, second information not easy to identify, improve the efficiency of fuzzy matching.
S132. whether identification number in distress is judged to be used in the second information of comparison in the number-plate number that comprises, difficult identification number is in physics license plate image identifying because external environment is severe etc., and reason is difficult to the number of identification, the error of this number is larger, exactly because likely the identification error of difficult identification number just can cause the first information and the second information precisely to mate, therefore determine that difficult identification number is significant to fuzzy matching, if forgone, this difficult identification number, very likely obtains information of vehicles matching result more accurately.If identification number in distress, enters step S133, if without difficult identification number, enter step S135.Preferably, step S132 comprises:
S1321. the degree of confidence of each number in the number-plate number being used for comprising in the second information of comparison is obtained.In embody rule, any one confidence calculations method in prior art of can choosing obtains the degree of confidence of each number in the number-plate number comprised in the second information for comparison.
S1322. judge whether to there is the number of degree of confidence lower than preset number degree of confidence.By by the degree of confidence of number compared with preset number degree of confidence, be easy to determine difficult identification number.
If S1323. exist, then using degree of confidence lower than the number of preset number degree of confidence as difficult identification number.Degree of confidence is low, and the with a low credibility of this Number Reorganization is described, if lower than the degree of confidence of preset number, then illustrate in physics license plate image identifying, the identification error of this number is comparatively large, i.e. difficult identification number code.
