Paper money processing method and device

Abstract

The embodiment of the invention discloses a paper money processing device and method. Because the new and old degree or dirt degree causes little effect on an infrared image, a white light reflectogram, an infrared reflection image and a transmission image of paper money are collected through an optical sensor, and the sort of currency and the face value of the paper money are recognized through image feature template matching, the crown character number of the paper money is accurately positioned through the infrared reflection image and the infrared transmission image of the paper money on the basis, the crown character number can be accurately positioned on the white light reflection image after the positioning result is mapped to the white light reflection image, and then character segmentation and character recognition can be performed. The paper money processing device and method can effectively eliminate the effect on the positioning of the crown character number area when the crown character number area is dirty and thus effectively improve the recognition rate of the crown character number.

Description

technical field [0001] The embodiments of the present invention relate to the field of banknote processing, and in particular to a banknote processing method and device. Background technique [0002] In recent years, with the rapid development of world economy and technology, all kinds of financial self-service equipment have been applied in various fields of people's daily life.

Problems solved by technology

However, when the banknotes are old, there are stains in the serial number area, or the image acquisition parts of the self-service equipment are aging due to long-term use, the white light image of the banknote is noisy and has a lot of interference, which is not conducive to the effective positioning of the serial number area. Financial self-service equipment often has the problem of inaccurate interception of banknote serial number images. The inaccurate interception of the image of the serial number area greatly reduces the banknote traceability function of financial self-service equipment, which seriously affects the "anti-counterfeiting and anti-counterfeiting" ability of financial self-service equipment. The key It is impossible to provide judicial evidence with reference value for the judiciary at all times
