Problems solved by technology
However, most of the existing fingerprint databases are contact fingerprints, and it is time-consuming and laborious to re-acquire new non-contact fingerprints as a fingerprint database. especially important
[0003] Most of the traditional fingerprint matching technology is based on the minutiae-based method. This method has confirmed its effectiveness in the traditional fingerprint matching in the past. However, due to the combination of non-contact fingerprint acquisition sensor and contact fingerprint acquisition sensor The distributions are different, and there will be some gaps between the fingerprints collected by the two. These gaps make the results obtained by the traditional method unsatisfactory. The traditional method to solve this difference is to use the image degradation correction algorithm to eliminate the two Acquisition differences between sensors, but poorly

The invention belongs to the field of biological feature authentication, and discloses a contact fingerprint and non-contact fingerprint matching method and a related device, and the method comprises the steps: obtaining a to-be-matched contact fingerprint and a to-be-matched non-contact fingerprint; extracting minutiae of the contact fingerprint and the non-contact fingerprint, and sampling according to the minutiae of the contact fingerprint and the non-contact fingerprint to obtain sampled fingerprints of the contact fingerprint and the non-contact fingerprint; inputting the contact type fingerprint, the sampling fingerprint of the contact type fingerprint, the non-contact type fingerprint and the sampling fingerprint of the non-contact type fingerprint into a preset fingerprint matching neural network model to obtain high-dimensional feature vectors of the contact type fingerprint and the non-contact type fingerprint; according to the similarity between the high-dimensional feature vectors of the contact fingerprints and the non-contact fingerprints, the matching result of the contact fingerprints and the non-contact fingerprints is obtained, the matching accuracy of the contact fingerprints and the non-contact fingerprints is improved, and the method can be more effectively applied to actual application scenes.
Description
technical field [0001] The invention belongs to the field of biometric authentication, and relates to a method for matching a contact fingerprint and a non-contact fingerprint and a related device. Background technique [0002] Non-contact fingerprints are not easily contaminated, easy to collect, and not in contact with other people during the collection process. Moreover, compared with the collection process of contact fingerprints, the collection of non-contact fingerprints is less likely to infect viruses. Therefore, non-contact fingerprints have received more and more attention from academia and industry in recent years. However, most of the existing fingerprint databases are contact fingerprints. It is time-consuming and laborious to re-collect a new non-contact fingerprint as a fingerprint database. Therefore, it is difficult to study the matching method between non-contact fingerprints and contact fingerprints, which is different from the traditional method. especia...
