[0051] In this embodiment, the mobile phone 1 can not only determine the license plate image, but also recognize the license plate number in the license plate image. Therefore, the structure of the license plate recognition and payment system of the present application is more simple.

[0052] In one embodiment, when the recognition device 2 is unavailable, the mobile phone 1 is used to obtain the license plate image of the vehicle, and the mobile phone 1 includes a color recognition module and a screenshot module, and the trigger module and the screenshot module are communication links.

[0053] The trigger module is used to determine the license plate recognition area and identify the color change in the license plate recognition area after the camera of the mobile phone 1 is aligned with the license plate.

[0054] The screenshot module is used to take a screenshot of the license plate recognition area through the screenshot function of the mobile phone 1 to obtain a license plate image after the trigger module recognizes the color change of the license plate recognition area 11.

[0055] In this embodiment, after the camera of the mobile phone 1 is fixed, the vehicle is parked in front of the camera, and the license plate position, that is, the position where the virtual coil is drawn, is the license plate recognition area. When the license plate is in the license plate recognition area, the color of the license plate recognition area will change, and at this time the trigger module sends information to the screenshot module, and the screenshot function of the mobile phone 1 is used to take a screenshot of the license plate recognition area, thereby obtaining a license plate image.

[0056] In another embodiment, when the recognition device 2 is unavailable and the mobile phone 1 is used to obtain the license plate image of the vehicle, the license plate payment system further includes a data processing module, and the data processing module and the recognition module are communication-linked, and the data processing module is used to determine the license plate image after the camera of the mobile phone 1 is aligned with the license plate.

[0057] In this embodiment, after the camera of the mobile phone 1 is fixed, the vehicle is parked in front of the camera, and the license plate position, that is, the position where the virtual coil is drawn, is the license plate recognition area. When the license plate is in the license plate recognition area, the mobile phone 1 sends it to the data processing module, the data processing module determines the license plate image, and then sends it to the image processing module to recognize the license plate number.

[0058] Optionally, the license plate recognition and payment system further includes a billing module, which is in communication with the image processing module, wherein the billing module is used to perform billing processing on the license plate number recognized by the image processing module.

[0066] In this embodiment, after the camera of the mobile phone 1 is fixed, the vehicle is parked in front of the camera, and the license plate position, that is, the position where the virtual coil is drawn, is the license plate recognition area. When the license plate is in the license plate recognition area, the color of the license plate recognition area will change, and at this time the trigger module sends information to the screenshot module, and the screenshot function of the mobile phone 1 is used to take a screenshot of the license plate recognition area, thereby obtaining a license plate image.

[0067] Optionally, recognizing the license plate number in the license plate image by an image processing module includes:

[0068] After the screenshot module takes a screenshot of the license plate recognition area through the OCR recognition module of the mobile phone 1, the license plate number of the license plate image is recognized through the image processing function of the mobile phone 1.

[0069] In this embodiment, when the recognition device 2 is available, the vehicle's license plate image is obtained through the recognition device 2, the recognition device 2 is communicated with the mobile phone 1 in the image processing module, the recognition device 2 sends the license plate image to the mobile phone 1, and the license plate number of the license plate image is recognized through the OCR recognition module of the mobile phone 1.

[0070] When the recognition device 2 is unavailable, the vehicle license plate image is obtained through the mobile phone 1. The screenshot module of the mobile phone 1 takes a screenshot of the license plate recognition area and sends it to the OCR recognition module, which uses the image processing function of the mobile phone 1 to recognize the license plate number in the license plate image.

[0071] Optionally, after the license plate number in the license plate image is identified by the image processing module, the license plate number data is uploaded to the billing module.

[0072] In this embodiment, after the license plate number is identified, the fee to be paid is calculated through the billing module, and the fee is paid by scanning the code and then the car leaves the parking lot.
