Embodiment 1

[0068] like figure 1 As shown, an embodiment of the present invention provides a visible light-based vehicle license plate detection system, including a cloud traffic management server, at least one collection terminal, and at least one vehicle terminal; wherein, the cloud traffic management server includes a cloud digital watermarking module and a cloud detection module. the collection end includes a collection end visible light module; the vehicle end includes a vehicle end visible light module; the collection end and the vehicle end perform visible light communication interaction through the collection end visible light module and the vehicle end visible light module;

[0069] The collection terminal is used to collect the vehicle number plate image of the vehicle terminal in real time and obtain the vehicle identification code of the vehicle terminal from the vehicle terminal;

[0070] The cloud-based digital watermarking module is used for identifying and / or extracting th...

Embodiment 2

[0082] like figure 2 As shown, on the basis of the above embodiment, the difference between the embodiment of the present invention and the embodiment 1 is that the collection end includes a camera module and a collection end processing module;

[0083] The camera module is used to photograph the vehicle number plate of the vehicle end in real time and obtain the image of the vehicle number plate;

[0084] The acquisition-end processing module is configured to collect the vehicle number plate image of the vehicle-end collected by the camera module and the vehicle identification code information of the vehicle-end collected by the collection-end visible light module, and associate with the vehicle identification code information. The cloud traffic management server communicates and sends and receives corresponding information, so that the cloud traffic management server can perform detection and verification processing on the authenticity of the vehicle number plate and check ...

Embodiment 3

[0088] On the basis of the above-mentioned embodiments, such as image 3 As shown, in this embodiment of the present invention, the cloud traffic management server further includes a cloud security module, the collection end further includes a collection end security module, and the vehicle end further includes a vehicle end security module;

[0089] The cloud security module, the collection terminal security module and the vehicle terminal security module are respectively used to provide a password service function and a secure storage function for the cloud traffic management server, the collection terminal and the vehicle terminal;

[0090] The vehicle identification code of the vehicle end is built into the security storage area of ​​the vehicle end security module by the vehicle manufacturer before the vehicle leaves the factory, and the vehicle identification code is built into the security storage area of ​​the vehicle end security module. Afterwards, only a read-only f...

Abstract

The invention provides a vehicle license plate detection system and method based on visible light. The system includes: a cloud traffic management server, at least one collection terminal, and at least one vehicle terminal; wherein, the cloud traffic management server includes a cloud digital watermark module and a cloud detection module; the collection terminal includes a collection terminal visible light module; the vehicle terminal includes a vehicle terminal visible light module; The end and the car end perform visible light communication interaction through the visible light module of the collection end and the visible light module of the car end; Identify and / or extract the digital watermark embedded in the vehicle license plate image and / or extract the cloud detection module, which is used to verify whether the vehicle license plate is a legal and safe vehicle license plate and vehicle number based on the digital watermark, vehicle license plate image and vehicle identification code Whether the card is a deck.

Description

technical field [0001] The invention relates to the field of license plate recognition technology and visible light communication technology, and in particular, to a system and method for detecting a vehicle cover plate based on visible light. Background technique [0002] Vehicles with sets of license plates generally refer to motor vehicles that use forged or altered license plates, license plates of other vehicles, or use deception or bribery to obtain license plates. The act of cheating disrupts the economic order of the country, disrupts the operational order of the transportation market, creates social instability, and seriously infringes upon the legitimate rights and interests of the original legitimate car owners. The harm cannot be underestimated. [0003] The existing anti-counterfeiting technical solutions mainly include adding anti-counterfeiting films and anti-counterfeiting patterns that can be recognized under visible light or special lighting conditions on t...
