Abstract
The invention relates to an image identification technology-based license plate identification method. On the basis of vehicle partial feature information and background database information, a searching range of a license plate-covered vehicle is gradually reduced, thereby achieving an objective of assisted identification of a license plate-covered law-breaking vehicle. The provided identification method is characterized in that: an electronic eye, a local storage unit, a covering identification module, a data sending module, a background data receiving module, a background storage unit, a feature identification and extraction unit, a database processing unit, and a vehicle information database. According to the invention, real-time analyzing, identifying and sending are carried out on vehicle information shot by the electronic eye; after the background receives an image, the image is analyzed and queried; one piece of a group of vehicle information is returned; and a relevant comparison operator only needs to carry out comparison on the one piece of the group of vehicle information. Therefore, the work load of the relevant comparison operator is substantially reduced; and the efficiency for illegal behavior identification of license plate covering can be substantially improved.
Description
Technical field
The present invention relates to a kind of recognition methods to car plate based on image recognition technology, based on vehicle sections characteristic information and back-end data library information, progressively dwindle the hunting zone of shield car plate vehicle, reach the auxiliary object of blocking car plate illegal vehicle of distinguishing.
Background technology
Block car plate and refer to multiple gimmick shield portions or whole car plate, realize camouflage.In recent years, owing to can not get Valid Regulation, the behavior of blocking car plate grows in intensity, and has presented new trend: part driver is usingd new " behave " that this evades punishment as irregular driving, What is more, and law-breaker is also using this as the new tool of covering its criminal offence.
The vehicle operating image that the present invention utilizes road electronic eyes to catch in real time, analyzes and tentatively determines whether car plate is blocked image; And the vehicle of the car plate that is blocked is further processed to (characteristic informations such as color, vehicle that extract the definite character information of car plate, vehicle), according to these features, Relational database is inquired about, progressively determine suspect vehicle or lock it in a specific scope, thereby greatly improving the efficiency of distinguishing the illegal vehicle that blocks car plate.
Summary of the invention
1. technical matters to be solved
The object of the invention is to block by distinguishing the scope that the feature of car plate vehicle is carried out secondary locking vehicle or dwindled vehicle query, improve and investigate and prosecute the efficiency of blocking car plate illegal activities.
2, technical scheme
The invention provides a kind of recognition methods to car plate based on image recognition technology, comprise electronic eyes, local storage unit, block identification module, data transmission blocks, back-end data receiver module, background storage, feature identification and extraction unit, database processing unit, vehicle information database.Electronic eyes is for taking passing vehicle, Information Monitoring; The vehicle image that local storage unit is taken for store electrons eye; Block identification module and whether have the possibility of blocking for preliminary identification vehicle; Data transmission blocks is for sending to the further analyzing and processing of background server by the vehicle image photographing (existence is blocked possible); Back-end data receiver module is for receiving the image information that electronic eyes end is sent; Background storage is for the image information of storing received, to further analyze; Feature identification and extraction unit, for the image information of analyzing stored unit, extracts the correlated characteristic of car, such as part car plate symbol, color, vehicle etc.; Database processing unit, according to the vehicle characteristics value enquiring vehicle information database extracting, is therefrom found out one or one group of data information of vehicles; Vehicle information database is for the relevant information of store car.
3, beneficial effect
The present invention carries out real-time analysis, distinguishes, sends according to the information of vehicles that electronic eyes is taken, backstage is analyzed in time, is inquired about after receiving image, and return to one or one group of information of vehicles, relevance ratio only need be carried out further comparison to personnel from this or one group of information.This has not only reduced the workload of relevance ratio to personnel widely, and has improved widely the efficiency of distinguishing license plate shading illegal activities.
By installing one at electronic eyes end, block identification module, the image information of taking is carried out to rough handling, judge whether it exists the possibility of license plate shading, and may exist the vehicle image information of license plate shading to be sent to traffic control department background server (background server is further analyzed, inquires about, distinguished).This greatly reduces the communication of big data quantity.
Accompanying drawing explanation
fig. 1 is system architecture schematic diagram of the present invention.
Fig. 2 is workflow diagram of the present invention.
As Fig. 1, native system is divided into two systems: electronic eyes end system and background server.Electronic eyes end system is comprised of 4 parts, is respectively electronic eyes, and storage unit is blocked identification module and data transmission blocks; Background server comprises data reception module, storage unit, feature extraction unit, database processing unit and vehicle information database.
Embodiment
The present invention is mainly that the various features of the vehicle by car plate is blocked is identified, and assists and distinguishes the definite information of illegal vehicle or be limited in specific seek scope, to improve the efficiency of relevance ratio to personnel, determines in time associated vehicle and makes punishment.
With reference to the accompanying drawings the present invention is made to following specific description.As shown in Figure 1, the initial analysis by the vehicular traffic of electronic eyes end shooting, judges whether this car exists license plate shading.If have, send to background server further to analyze, and by vehicle characteristics query-relevant data storehouse, backstage, Query Result is returned to related personnel, realize car plate the auxiliary of vehicle that be blocked and distinguish.
As accompanying drawing 2, specific works flow process is as follows:
1. electronic eyes is taken passing vehicle, and stores, and proceeds to 2.
2. block identification module the image information of storing in storage unit is analyzed, judge that whether it has the possibility of blocking car plate, if having, proceeds to 3; Otherwise, assert that this car is unshielding car plate vehicle, does not do any operation to image.
3. data transmission blocks sends to background server by blocking the license plate shading image that is suspected to be that identification module filters out, and proceeds to 4.
4. what back-end data receiver module reception electronic eyes end was sent is suspected to be that license plate shading Image Saving, in storage unit, proceeds to 5.
5. eigenwert extraction unit is done further to analyze to the license plate shading image that is suspected to be of preserving in storage unit, and adopts image processing techniques to extract the features such as its color, vehicle, number plate symbol.If the features such as its number plate symbol all can not be identified, proceed to 8; Otherwise, proceed to 6.
6. the eigenwert that is suspected to be license plate shading image that database processing module extracts according to eigenwert extraction unit is inquired about in vehicle information database, if can find one or one group of result, proceeds to 7; Otherwise, proceed to 9.
By the result store inquiring in storage unit, and show to related personnel, so that it judges.
8. think that this car car plate is all blocked, its image information is saved in to the specific region in storage unit, proceed to manual processing links.
9. think this automobile storage deck or false license plates may, its image information is saved in to another specific region in storage unit, proceed to manual processing links.
