QUALITY CONTROL METHOD FOR PAPER MONEY AUTHENTICATION AND SYSTEM THEREFOR

摘要

A quality control method for paper money authentication is used to solve the technical problems that due to differences in paper money classification results caused by differences in performances of a CIS, the identification accuracy of paper money is affected and the risk of incorrect identification exists. The method in the embodiments comprises: acquiring a multi-spectrum signal collected by a CIS; extracting a first eigenvalue of the multi-spectrum signal; obtaining a corresponding second eigenvalue according to the first eigenvalue and a pre-set correction conversion value; and inputting the second eigenvalue into a paper money classifier to obtain a corresponding paper money classification result. Also provided is a quality control system for paper money authentication. The embodiments can solve the technical problems that due to differences in paper money classification results caused by differences in the performances of the CIS, the identification accuracy of paper money is affected and the risk of incorrect identification exists.
