Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides the recognition methods of a kind of fake license plate vehicle.With reference to the identification side that Fig. 1, Fig. 1 are fake license plate vehicle of the present invention
The schematic flow sheet of method first embodiment.
In the present embodiment, the recognition methods of this fake license plate vehicle includes:
Step S10, acquisition is through the image information of each vehicle of bayonet socket；
Wherein, bayonet socket, refer to be provided with the equipment of the image to road vehicle and information and identification
Control point or place, can collect substantial amounts of information of vehicles every day, such as, at the traffic block port that some are important, as the most public
Road charging aperture, public security inspection post etc., it will usually utilize the camera head laid, to each vehicle of process shoot,
And the bayonet vehicle image photographed is saved in data base, in order to follow-up carrying out is retrieved and checks, bayonet vehicle image
It can be vehicle frontal image.In actual applications, which bayonet vehicle image being defined as search object can be according to actual need
Depending on Yaoing, the seeking scope searched as each bayonet vehicle image composition fake license plate vehicle searching object.
In the present embodiment, then can come based on image information by obtaining the image information of each vehicle through bayonet socket
Realize the identification of fake license plate vehicle, specifically, first the vehicle image that the camera head of each bayonet socket shoots can be stored
In data base or in server, then timing acquisition is through the image information of each bayonet vehicle, the time of its timing acquisition
Interval can the most reasonably set.
Step S20, obtains the license board information that described image information is corresponding；
In the present embodiment, getting image information, image information is being carried out image recognition, obtains image information corresponding
License board information.
Step S30, when there is currently the consistent license board information of license plate number, obtains the described license board information that license plate number is consistent
The corresponding preset travel duration between different bayonet sockets；
In the present embodiment, when there is currently the consistent license board information of license plate number, the described car consistent for determining license plate number
Whether vehicle corresponding to board information is deck suspected vehicles, the difference that the consistent described license board information of the trade mark of picking up the car further is corresponding
Preset travel duration between bayonet socket, wherein it is possible to by different bayonet sockets corresponding to the consistent described license board information of license plate number it
Between shortest path and maximum travelling speed obtain preset travel duration；Can also be according to the consistent described license board information of license plate number
The bayonet socket information of corresponding different bayonet sockets searches the preset travel duration of correspondence in default data base, and preset travel duration can
To precalculate and to be stored in default data base according to the shortest path between different bayonet sockets and maximum travelling speed, with
It is easy to when fake license plate vehicle identification directly invoke the preset travel duration of correspondence.
It is emphasized that when there is currently the consistent license board information of license plate number, if the described car plate that license plate number is consistent
The bayonet socket of information process is same bayonet socket, it is determined that this vehicle is not deck suspected vehicles.
Step S40, is less than at vehicle corresponding to the license board information that license plate number is consistent traveling duration between different bayonet sockets
During described preset travel duration, determine that the vehicle meeting the license board information of above-mentioned condition corresponding is deck suspected vehicles.
Wherein, vehicle corresponding to license plate number is consistent license board information traveling duration between different bayonet sockets can be according to car
Vehicle corresponding to the consistent described license board information of the trade mark is calculated by the time point of corresponding bayonet socket.
In the present embodiment, little at vehicle corresponding to the license board information that license plate number is consistent traveling duration between different bayonet sockets
When described preset travel duration, determine that the vehicle meeting the license board information of above-mentioned condition corresponding is deck suspected vehicles, specifically
Refer to when in the license board information that license plate number is consistent, corresponding vehicle traveling duration between different bayonet sockets is less than described preset travel
Time long, should the duration that travels between different bayonet sockets be deck suspected vehicles less than the vehicle of described preset travel duration.Typically
In the case of, the vehicle with legal car plate can travel according to traffic law in the process of moving, its row between different bayonet sockets
Sail duration and be more than preset travel duration (except certain emergency), and fake license plate vehicle is likely in the process of moving not according to friendship
Logical regulation travels, and such as, exceeds the speed limit, makes a dash across the red light, at vehicle corresponding to the license board information that license plate number is consistent between different bayonet sockets
Traveling duration less than described preset travel duration time, it is possible to determine that this vehicle is deck suspected vehicles (police car, rescue accurately
Except car, fire fighting truck etc.).
Further, in one embodiment, step S20 includes: described image information carries out image recognition to obtain institute
State the license board information that image information is corresponding.
In the present embodiment, getting image information, image information is being carried out image recognition, obtains image information corresponding
License board information.Wherein, image recognition algorithm image information carrying out image recognition can use existing image recognition algorithm.
Further, in another embodiment, step S10 includes: obtain the high-definition camera bat being arranged on each bayonet socket
The image information of each vehicle through bayonet socket taken the photograph.
In the present embodiment, for improving the definition of image information, improve accuracy rate and the efficiency of deck suspected vehicles identification,
The filming apparatus arranged at each bayonet socket is high-definition camera.
The recognition methods of the fake license plate vehicle that the present embodiment proposes, by obtaining the image information of each vehicle through bayonet socket,
Then obtaining the license board information that described image information is corresponding, then when there is currently the consistent license board information of license plate number, obtaining
Preset travel duration between the different bayonet sockets that described license board information that license plate number is consistent is corresponding, finally at the car that license plate number is consistent
When vehicle corresponding to board information traveling duration between different bayonet sockets is less than described preset travel duration, determines and meet above-mentioned bar
The vehicle that the license board information of part is corresponding is deck suspected vehicles, it is achieved that according to vehicle traveling duration between different bayonet sockets with
And preset travel duration judges whether this vehicle is deck suspected vehicles, wherein, when length is less than described preset travel in motion
Time long, determine that this vehicle is deck suspected vehicles, it is possible to identify deck suspected vehicles accurately, improve fake license plate vehicle identification
Accuracy rate and efficiency.
