具体实施方式Detailed ways
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
本发明主要提供一种含有光学隐码的防伪车牌，在普通车牌的基础上，在车牌表面喷涂上隐式光学密码信息，即光学隐码，作为确定车辆所带的车牌的真伪。光学隐码使用在不可见光波段的特定波长上发光的光学材料，这样，将光学隐码喷涂到车牌上之后，在可见光情形下，光学隐码是不发光的，含有光学隐码的车牌看上去跟普通车牌没有任何区别，加大了仿造的难度。在本实施例中，采用可见光波段不发光，红外光波段发光的光学材料喷涂光学隐码，光学隐码中包含车辆的防伪信息，其包括发动机号、车牌号、车架号、型号、制造年份以及驾驶者身份个人数据中的一种或几种，所包含的防伪信息以能够唯一确定车辆为准。光学隐码可以喷涂成一维条形码形式或者二维条形码形式。该防伪车牌制作简单，只需选定在不可见光波段的特定波长上发光的光学材料，使用条形码的喷涂方式，即可实现防伪车牌的制作。The present invention mainly provides an anti-counterfeiting license plate containing optical hidden codes. On the basis of ordinary license plates, hidden optical code information, that is, optical hidden codes, is sprayed on the surface of the license plate to determine the authenticity of the license plate carried by the vehicle. The optical hidden code uses optical materials that emit light at a specific wavelength in the invisible light band. In this way, after the optical hidden code is sprayed on the license plate, the optical hidden code does not emit light under visible light, and the license plate containing the optical hidden code looks There is no difference from ordinary license plates, which increases the difficulty of counterfeiting. In this embodiment, an optical material that does not emit light in the visible light band and emits light in the infrared light band is used to spray the optical hidden code. The optical hidden code contains the anti-counterfeiting information of the vehicle, which includes the engine number, license plate number, frame number, model, and year of manufacture. As well as one or more of the personal data of the driver's identity, the anti-counterfeiting information contained in it shall be subject to the unique identification of the vehicle. The optical hidden code can be sprayed in the form of a one-dimensional barcode or a two-dimensional barcode. The production of the anti-counterfeit license plate is simple, and the production of the anti-counterfeit license plate can be realized by selecting an optical material that emits light at a specific wavelength in the invisible light band, and using a barcode spraying method.
防伪车牌的检测识别方法的一个实施例的装置示意图如图1所示，识别流程图如图2所示。本实施例采用特定的红外光源以某一角度照射车牌，经过红外光的照射，车牌表面喷涂的光学隐码发光，此时使用摄像头装置获取光学隐码信号，将获得的信号经过信息识别与还原处理，利用现有的条形码的识别装置读取出光学隐码中所包含的防伪信息，与车辆信息库中原始记录的车辆信息相比对，判断出车牌的真伪。本实施例中光学隐码的读取速度快，精度高。可将本实施例中的防伪车牌检测设置为固定式检测系统置于交通要道及特需探测点，设置为手持式检测装置可便于个人携带；适宜用于停车场、不同密级门禁、车库、收费卡口、交通路口、流动交警、小区物业等场所的管理与调度工作。The device schematic diagram of an embodiment of the method for detecting and recognizing anti-counterfeit license plates is shown in FIG. 1 , and the recognition flow chart is shown in FIG. 2 . This embodiment uses a specific infrared light source to irradiate the license plate at a certain angle. After the irradiation of infrared light, the optical hidden code sprayed on the surface of the license plate emits light. At this time, the camera device is used to obtain the optical hidden code signal, and the obtained signal is identified and restored. For processing, use the existing barcode recognition device to read the anti-counterfeit information contained in the optical hidden code, compare it with the original recorded vehicle information in the vehicle information database, and judge the authenticity of the license plate. In this embodiment, the reading speed of the optical hidden code is fast and the precision is high. The anti-counterfeiting license plate detection in this embodiment can be set as a fixed detection system placed in the traffic arteries and special detection points, and it can be set as a hand-held detection device, which can be easily carried by individuals; it is suitable for parking lots, different security levels of access control, garages, charging Management and scheduling of checkpoints, traffic intersections, mobile traffic police, community property and other places.
由以上实施例可以看出，本发明实施例通过采用隐形发光材料，在正常环境下看不出与普通车牌的差别，只在特定波段的光源照射下才能发光进行识别，防伪性强；另外，直接将隐形发光材料喷涂到汽车牌照表面，制作工艺简单。It can be seen from the above embodiments that the embodiment of the present invention adopts invisible luminescent materials, and the difference from ordinary license plates cannot be seen under normal circumstances, and can only be identified by emitting light under the illumination of a light source of a specific wavelength band, and has strong anti-counterfeiting properties; in addition, The invisible luminescent material is directly sprayed on the surface of the license plate, and the manufacturing process is simple.
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and replacements can also be made, these improvements and replacements It should also be regarded as the protection scope of the present invention.
