Problems solved by technology

[0003] At present, the traditional fingerprint identification technology still has certain limitations and cannot be applied to the tail box unlocking control with high quality.
On the one hand, the traditional fingerprint matching process cannot guarantee a high accuracy rate, which directly affects the recognition accuracy of fingerprints; on the other hand, the traditional fingerprint recognition model often does not have good universality. It is difficult to judge the detection image

Abstract

The invention proposes an application method and equipment for fingerprint recognition of intelligent tail boxes based on training samples, and relates to the field of safes. The solution of the present invention: use multiple models such as multi-scale image detail optimization processing, autoencoder, SVM (support vector machine), grouped KNN to distinguish whether it is the fingerprint of the smart tail box holder, and it is the fingerprint of the smart tail box. Support for safe use. The invention can improve the accuracy and robustness of fingerprint image recognition and ensure the safe use of the smart tail box.

Description

technical field [0001] The invention relates to the field of safes, in particular to an application method and equipment for identifying smart tail boxes based on training sample fingerprints. Background technique [0002] Smart tail boxes have played an important role in the financial field and are increasingly recognized by the public. It can not only provide users with great convenience, but also guarantee the safety of funds and important documents to a certain extent. Since a large amount of funds and important documents are stored in the smart tail box, its use security has attracted more and more attention. Combined with artificial intelligence technology, many well-known research institutions and high-tech companies apply fingerprint recognition technology to smart tail boxes, and use fingerprint recognition to unlock and control smart tail boxes, aiming to improve the safety of smart tail boxes. [0003] At present, the traditional fingerprint identification techn...
