According to another aspect of the disclosure, there is provided a method for identifying license plate tampering which is applied into the above mentioned apparatus for identifying license plate tampering. As shown in FIGS. 1 and 2, the method includes the steps of:

Step 21, obtaining a vehicle image.

Specifically, a camera captures a vehicle image and sends the vehicle image to an image obtainer 1.

Step 22, obtaining a license plate number image in the vehicle image.

Specifically, the image obtainer 1 cuts out the license plate number image automatically from the vehicle image.

Step 23, determining whether the license plate of the vehicle is blocked according to the license plate number image. If the license plate of the vehicle is not blocked, move to step 24; otherwise, move to step 27.

Specifically, the image obtainer 1 sends the license plate number image to the third identifier 5 which determines whether the license plate of the vehicle is blocked according to the license plate number image. If the license plate of the vehicle is not blocked, it is further determined whether the vehicle information is consistent with the standard vehicle information in the vehicle information base (i.e., performing step 24); otherwise, if the license plate of the vehicle is blocked, the vehicle is recorded as a vehicle with a blocked license plate (i.e., performing step 27).

Step 24, determining whether the vehicle information contained in the vehicle image is consistent with the standard vehicle information in the vehicle information base. If not consistent, move to step 25; otherwise, the procedure is ended.
