Problems solved by technology
However, the above-mentioned fingerprint type canteen card swiping device still has many deficiencies, which are specifically manifested in: the fingerprint type canteen card swiping device is a contact device, long-term use will cause equipment wear and tear, and the sensitivity will decrease. If other substances are stuck on the hand, it will affect the recognition effect and cause Unable to pay, and because each person's fingerprint carries less characteristic information, the false recognition rate of fingerprint recognition is higher than other biometric technologies, and the security performance needs to be improved

The invention relates to the technical field of iris recognition, in particular to a dining hall card swiping method and system based on iris recognition. The method comprises the steps of inputting a due meal price; collecting a whole eye image of a payer; extracting a needed iris image from the collected while eye image; extracting iris image features from the iris image, and generating a feature vector according to the iris image features; comparing the generated feature vector with teachers' and students' irises and an IC card account database, and finding out a corresponding iris serial number; according to the iris serial number, searching the teachers' and students' irises and the IC card account database for a corresponding IC card account serial number, and executing fee deduction under the account corresponding to the IC card account serial number according to the input due meal price. According to the dining hall card swiping method based on iris recognition, iris collection is of a non-contact type; compared with a contact type fingerprint collection device, the iris collection device does not need to be replaced frequently, software just needs to be updated selectively as needed, and the cost performance is higher.
Description
technical field [0001] The invention relates to the technical field of iris recognition, in particular to a canteen card swiping method and system based on iris recognition. Background technique [0002] At present, the card swiping devices used in school canteens are generally non-contact IC card canteen card swiping devices. This kind of card swiping device has the advantages of being electronic and convenient, and does not require cash transactions, effectively avoiding the need for change belts in cash transactions. Come trouble. [0003] With the development of information technology and pattern recognition technology, biometric recognition technology is also applied to payment consumption, which enriches the payment methods and simplifies the payment process. The fingerprint canteen card swiping device has a built-in fingerprint identification chip, and uses the fingerprint payment method to realize the payment. The feature information such as the characteristic point...
