Banknote identification method, device, terminal equipment and readable storage medium

Abstract

The invention belongs to the field of financial facilities, and particularly relates to a banknote identification method, a banknote identification device, terminal equipment and a readable storage medium. According to the banknote identification method, an infrared transmission image of a banknote to be identified is acquired, then a target region of a column pattern in the infrared transmissionimage is estimated according to a position of the column pattern in a standard banknote corresponding to the banknote to be identified, since the printing workmanship of a genuine banknote is exquisite, the column pattern can be ensured to be invisible under infrared transmission, the difference between the printing workmanship of a high-simulation abnormal banknote and that of the genuine banknote is great, and the obvious column pattern is shown under infrared transmission, thus the matching of the column pattern can be carried out in the target region, and the banknote to be identified canbe determined to be an abnormal banknote if the matching is successful. Compared with the prior art, the banknote identification method and the banknote identification device fully utilize the specialoptical properties of the abnormal banknote, and can significantly increase the accuracy of identifying abnormal banknotes.

Description

technical field [0001] The invention belongs to the field of financial equipment, and in particular relates to a banknote identification method, device, terminal equipment and readable storage medium. Background technique [0002] Banknote identification is one of the basic functions of various ATM machines.
