Abstract

The invention provides an intelligent trunk fingerprint identification method and system based on a high-quality template, and relates to the field of fingerprint identification. The method comprises the steps of obtaining a plurality of sample fingerprint images, then inputting the plurality of sample fingerprint images into a preset deep hash coding model to obtain a template fingerprint image, then obtaining a to-be-detected fingerprint image, and then performing image decomposition on the to-be-detected fingerprint image and the template fingerprint image, acquiring to-be-detected fingerprint images of multiple scales and template fingerprint images, performing sharpening processing on the to-be-detected fingerprint images of all the scales and the template fingerprint images of all the scales by using a sharpening convolution kernel to obtain sharpening results of all the scales, finally comparing the sharpening results of all the scales, and generating the identification result of the to-be-detected fingerprint image according to the comparison result, so that the comparison of the fingerprint images under multiple scales is realized, the fingerprint identification precision is improved, and the safe application of the intelligent trunk is ensured.

Description

technical field [0001] The invention relates to the field of fingerprint identification, in particular to a method and system for intelligent tail box fingerprint identification based on a high-quality template. Background technique [0002] With the rapid development of the financial industry, smart tail boxes are playing an increasingly important role. It not only provides great convenience for users, but also provides important support for protecting property safety. At the same time, problems such as improper operation and misappropriation by criminals have caused great hidden dangers to the safety of property in the financial field. Based on this, many research institutions and technology companies have focused on how to use fingerprint recognition technology to control the unlocking of smart tail boxes, aiming to better improve the safety of smart tail boxes. [0003] However, traditional fingerprint recognition methods for smart tail box applications often have the ...
