Embodiment 1

[0066] like figure 1 As shown, an embodiment of the present invention provides a vehicle deck detection system based on visible light, which is characterized by comprising: 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 generating module; the collection end includes a camera module, a visible light module at the collection end, a digital watermark identification module at the collection end, and a collection end processing module; the vehicle end includes a vehicle end visible light module; the collection end and the vehicle end pass through the The visible light module at the collection end and the visible light module at the vehicle end perform visible light communication interaction; the cloud traffic management server is communicatively connected with the collection end;

[0067] The cloud digital watermark generation module is used to gen...

Embodiment 2

[0083] On the basis of the above-mentioned embodiment, as Figure 4 As shown, the difference between this embodiment of the present invention and Embodiment 1 is that, 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 cloud security module. Including on-board security module;

[0084] 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;

[0085] 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 identificatio...

Embodiment 3

[0089] On the basis of the above embodiment 2, as Figure 5 As shown, in the embodiment of the present invention, the cloud traffic management server further includes a digital certificate module; the digital certificate module is used to generate and save public key certificates for the cloud traffic management server and the collection terminal respectively; the digital certificate module The certificate module writes the public key certificate of the collection terminal and the public key certificate of the cloud traffic management server into the security module of the collection terminal in an offline or online manner; the cloud traffic management server and the collection terminal respectively save their corresponding public key certificates. The private key corresponding to the public key in the key certificate; the private key of the cloud traffic management server is stored in the secure storage area of ​​the digital certificate module or the cloud security module; the...

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; the cloud traffic management server includes a cloud digital watermark generation module; the collection terminal includes a camera module, a collection terminal visible light module, a collection terminal digital watermark identification module and a collection terminal processing module ;The vehicle end includes the visible light module of the vehicle end; the cloud digital watermark generation module is used to generate digital watermark and embed the digital watermark into the ordinary vehicle license plate image to form a safe vehicle license plate image; The digital watermark embedded in the image is identified and / or extracted; the acquisition end processing module is used to collect the vehicle license plate image and the vehicle identification code collected by the camera module, based on the digital watermark, the vehicle license plate image and the vehicle identification code Verify that the vehicle number plate is a legitimate security vehicle number plate and that the vehicle number plate 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 from other vehicles, or use deception or bribery to obtain license plates. The act of cheating disrupts the management and control of public security, 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 should not be underestimated. [0003] The existing anti-counterfeiting technical solutions mainly include adding anti-counterfeiting films and anti-counterfeiting patterns that can be reco...
