Abstract
The utility model relates to a luminescence film license plate which comprises a license plate framework. The luminescence film license plate is characterized in that a cavity is formed in the license plate framework, a plane luminescence body is arranged inside the cavity, a hollowed-out part for marking license plate numbers is arranged on one side of the license plate framework, light is emitted by the plane luminescence body, and the light is emitted from the hollowed-out part to display the license plate numbers. The luminescence film license plate is provided with an organic electroluminescence film to enable the license plate to give out light, image information of the license plate numbers is actively sent out and can be easily captured by a license plate recognition system, and due to the facts that the luminescence film license plate actively gives out light, and obvious difference is generated between the luminescence film license plate and surrounding parts of the license plate, the fact that the recognition rate of the license plate is improved is facilitated.
Description
Technical field
The utility model relates to a kind of car plate of vehicle, relates in particular to the luminous car plate of a kind of energy.
Background technology
Along with the fast development of economic society, people's growth in the living standard, the quantity of power actuated vehicle is also more and more.Automotive license plate be in public can unique definite identity of automobile voucher.The strict laws and regulations on the management of a cover have been paid much attention to and formulated to China's traffic management system to the management of automotive license plate.Wherein making, installation, the maintenance to automotive license plate all requires to manage by formulation department is unified.On this basis, if develop a kind of system that can locate identification in public quickly and accurately to license plate automatically, safety management level and the efficiency of management of automobile will be improved greatly.
Location of Vehicle License Plate and identification are computer vision with mode identification technology in one of important subject of intelligent transportation field application, this technology field of application is very extensive, comprising: the magnitude of traffic flow detects, control of traffic with induce, gangway such as airport, harbour vehicle management, the district vehicles management, monitoring vehicle breaking regulation such as make a dash across the red light, do not stop and charge automatically, road junction check post vehicle monitoring, public parking area safe antitheft management calculates line time, and vehicle safety is antitheft, find out and stop designated vehicle etc.
License plate recognition technology based on image belongs to direct method, it is a kind of passive license plate intelligent identification Method, can under the vehicle-mounted transmitter situation of no any special-purpose transmission car plate signal, carry out untouchable information acquisition and real-time intelligent identification to the number-plate number of state of kinematic motion vehicle or quiescence vehicle.Compare with the indirect method recognition system, at first, this system has saved equipment and has settled and substantial contribution, thereby has improved economic benefit; Secondly, owing to adopted advanced Computer Applied Technology, so can improve recognition speed, solve the real-time problem preferably; Again, it is to identify according to image, thus the identification error of the participation by the people in can resolution system, and that additive method is difficult to the people is mutual.Therefore, the license plate recognition technology based on image has special advantages.
And because external environment light changes, condition effect such as dust, environmental change in season and car plate itself be contaminated and fuzzy are arranged in the light path, feasible Vehicle License Plate Recognition System based on image can not get good application; And a lot of methods all needs a large amount of numerical calculation, requirement of real time well.In order to solve the problem of image degradation, the way of taking at present is to adopt active infrared illumination shooting or use special sensor to improve the quality of image.Though improved discrimination, also caused the cost of investment of system excessive simultaneously, application narrows down, and can not generally apply.
The utility model content
The purpose of this utility model provides a kind of luminescent film car plate, to promote the image identification degree of car plate, is conducive to the car plate identification based on image.
The utility model is that the technical scheme that its technical matters of solution adopts is: a kind of luminescent film car plate, comprise the car plate framework, and be characterized in; Have cavity in the car plate framework, be provided with flat luminous body in the cavity, car plate framework one side has the hollow-out parts that indicates license plate number, and flat luminous body emits beam, and light appears from hollow-out parts, shows luminous license plate number.
Flat luminous body is organic electroluminescent.
The car plate framework is made up of backboard and panel, and the parallel snapping with panel of backboard forms cavity between backboard and the panel, backboard is planar shaped, and the edge of panel is provided with annular flanging, and the middle part of panel raises up, the annular flanging surrounds flat luminous body, and hollow-out parts is positioned on the panel.
Backboard and panel are provided with knock hole, pass this knock hole by tight fixed bolt backboard is connected with panel.
The beneficial effects of the utility model are: this car plate is provided with the organic electroluminescent film makes the trade mark luminous, initiatively send the graphicinformation of the trade mark, caught by Vehicle License Plate Recognition System easily, because its active illuminating, produce tangible difference with car plate peripheral part, be conducive to improve the discrimination of car plate.
Description of drawings
Fig. 1 is the front view of luminescent film car plate of the present utility model;
Fig. 2 is cross sectional view of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1 and Figure 2, luminescent film car plate of the present utility model, comprise car plate framework 2, has cavity in the car plate framework 2, be provided with flat luminous body 1 in the cavity, car plate framework 2 one sides have the hollow-out parts 221 that indicates license plate number, and flat luminous body 1 emits beam, light appears from hollow-out parts 221, shows luminous license plate number.
In the present embodiment, flat luminous body 1 is the organic electroluminescent film.
In the present embodiment, car plate framework 2 is made up of backboard 21 and panel 22, backboard 21 and panel 22 parallel snappings, and flat luminous body 1 is between backboard 21 and panel 22, and hollow-out parts 221 is positioned on the panel 22.
This car plate is provided with the organic electroluminescent film makes the trade mark luminous, initiatively sends the graphicinformation of the trade mark, is caught by Vehicle License Plate Recognition System easily, because its active illuminating produces tangible difference with car plate peripheral part, is conducive to improve the discrimination of car plate.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
