It should be noted that when determining that at least one of the color, form and texture of the character in any of the regions of the license plate number image is different from the corresponding at least one of the color, form and texture of the character in the standard license plate number image, the first identifier 2 may not determine the license plate of the vehicle to be a tampered license plate temporarily, but allows for further identification by human so as to further improve reliability.

In the exemplary embodiment of the disclosure, the apparatus for identifying license plate tampering may further comprise a second identifier 3. Correspondingly, the image obtainer 1 is further configured to send the vehicle image to the second identifier 3.

The second identifier 3 is configured to determine whether a vehicle information contained in the vehicle image is consistent with a standard vehicle information in a vehicle information base, and send a first identification command to the first identifier 2 when the vehicle information contained in the vehicle image is not consistent with the standard vehicle information in the vehicle information base. The first identifier 2 is configured to determine whether the license plate is tampered according to the received license plate number image and the preset standard license plate number image after receiving the first identification command. In an exemplary embodiment of the disclosure, the second identifier may be implemented as a DSP chip or an embedded chip. However, the second identifier of the disclosure is not limited thereto, but may also be any other device or comparison circuit that can compare the extracted vehicle information with the standard vehicle information in the vehicle information base.
