Description

TECHNICAL FIELD

[0001] The utility model relates to a clearing machine technical field, concretely is a kind of not suitable for circulation banknote identification equipment based on multi-light source fusion. BACKGROUND

[0002] The clearing machine, also known as banknote clearing machine, cash clearing machine, currency clearing machine, etc., is a kind of financial machine that integrates multiple technologies. It is mainly divided into two categories: coin clearing machine and banknote clearing machine. The coin clearing machine mainly detects, clears and counts coins, while the banknote clearing machine performs the above operations on banknotes. The clearing machine identifies various characteristics of banknotes or coins, such as size and color, through image processing algorithms. At the same time, it can also detect special marks such as watermark, magnetic ink and infrared fluorescence on banknotes to prevent the circulation of counterfeit banknotes. The clearing machine is widely used in banks, financial institutions, supermarkets, post offices, self-service ticket machines, automatic teller machines, vending machines and other occasions. It can not only improve people's work efficiency, but also reduce people's contact with currency, ensuring the safety and hygiene of currency.

[0003] The traditional not suitable for circulation banknote identification equipment contains residual old banknotes. Since the system processing mode commonly used by the clearing machine is mostly single processing of images collected by each sensor, this processing method cannot meet the detection and processing of high-precision complex situations, which makes the clearing machine lack in identifying the subtle features of banknotes, especially the wear, stains and writing marks on residual old banknotes. Its recognition ability is limited. Since these marks may cover or change the original features of banknotes, the clearing machine cannot accurately identify not suitable for circulation banknotes, and may misjudge or miss judge. Therefore, a not suitable for circulation banknote identification equipment based on multi-light source fusion is proposed. SUMMARY
