Abstract

The invention belongs to the field of financial machinery, and particularly relates to a banknote identification method and device, terminal equipment and a readable storage medium. The method comprises the steps of firstly, collecting an infrared transmission image of a banknote to be identified, and extracting a sub-image of a region, where luminous light-variable numbers are located, from the infrared transmission image; secondly, calculating an average gray value of a background region (namely a first background region) of the whole infrared transmission image and an average gray value ofa background region (namely a second background region) of the sub-image respectively, wherein since the printing process of the real currency is exquisite, the average gray values of the first and second background regions can be basically at the same level, since the process of the altered currency is very different from that of the real currency, obvious deviation can occur to the average grayvalues of the first and second background regions, and therefore the abnormal altered currency can be effectively identified. Compared with the prior art, the technical scheme can greatly improve theaccuracy of identifying the abnormal altered currency since the special optical properties of the altered abnormal currency are fully utilized.

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. Its main principle is to use various marks on banknotes to judge the authenticity of banknotes, so as to prevent counterfeit currency from entering the market and affecting the normal financial order. [0003] Guangcai light change is an anti-counterfeiting technology commonly used in banknotes. For example, the number "100" in the middle of the 2015 edition of the 100 yuan bill changed from red and blue in the original version to gold, and with the change of viewing angle, the number "100" The color of the will alternate between gold and green, with a band of light visible scrolling up and down the numbers. [0004] Existing banknote identification technology generally...
