Human face identification-based method for verifying consistency of library card and card holder

Abstract

The invention provides a human face identification-based method for verifying consistency of a library card and card holder. The human face identification-based method comprises the following steps ofS1, building card information base; S2, setting a face contrast threshold M1, a first side face contrast threshold M2 and a second side face contrast threshold M3; S3, acquiring and extracting card information; S4, acquiring, processing and extracting a human face image of the card holder; and S5, performing information contrast and processing on the card information and the human face image of the card holder. The face and the side face of the card holder are compared, the influence of face contrast deviation on side face contrast is considered, consistency verification of the card holder isperformed, the verification accuracy is high, an error is small, the efficiency is high, the speed is rapid, and the cheat of a falsely using a planar photo of the card holder is prevented during theconsistency verification process.

Description

technical field [0001] The invention relates to the field of library monitoring, in particular to a method for checking the consistency of library borrowing certificates and witnesses based on face recognition technology. Background technique [0002] The library needs to rely on the library card to enter the borrowed books. The existing library access control only verifies the authenticity of the library card. It often happens that someone fraudulently uses other library cards to enter the library to borrow books, which has a negative impact on the security and order of the library. Assuming responsibility, it is necessary to compare the identity of the library card with the user to determine whether the user is the owner of the library card. However, the existing identification comparison methods often rely on manual identification, that is, by observing the person holding the library card and the library card held by human eyes to judge whether the authentication is cons...

It often happens that someone fraudulently uses other library cards to enter the library to borrow books, which has a negative impact on the security and order of the library. Assuming responsibility, therefore, it is necessary to compare the identity of the library card with the user to determine whether the user is the owner of the library card

However, the existing identification comparison methods often rely on manual identification, that is, by observing the person holding the library card and the library card held by human eyes to judge whether the authentication is consistent. However, due to the large error of manual identification, the accuracy of identification Not high, but to recognize one by one, the recognition speed is very slow, and the workload of the staff is also heavy, which is very labor-intensive and inefficient
