Abstract
The present invention provides a method and system for RMB version recognition, which relate to the field of monetary recognition method. The method comprises the following steps: extracting the effective thickness data of the RMB in the row direction; detecting the metal line peaks of each data channel in the column direction of the effective thickness data; determining the presence of the metal line in the data channel based on the number of metal line peaks present in each data channel; and determining the version of RMB according to the position of the metal line. The recognition method of the present invention can determine the position and the version of the metal line by detecting the metal line peak data of the area where the RMB security line is located, and is not affected by the characteristics of the RMB itself, such as the paper sample wear and tear. The operation is simple enough to realize rapid and convenient RMB version recognition.
