Library card and certificate comparison method

Abstract

The library card and certificate comparison method comprises the following steps: S1, establishing a library card information database; S2, setting a comparison threshold; S3: performing acquisition and extraction of library card information; S4: performing collection, processing and extraction of the face image of the holder; 5, comparing that information of the library card with the informationof the face image of the holder of the library card; 6, processing that comparison result; The invention compares the right face and the side face of the card holder at the same time, The side face comparison result is added into the positive face comparison result to judge whether the witness is cheating or not, so that the witness consistency test can be carried out with high precision, small error, high efficiency and fast speed, and the cheating in the witness consistency test process by using the plane photograph of the library card owner by the fraudulent user is avoided.

Description

technical field [0001] The invention relates to the field of library monitoring, in particular to a method for comparing library borrowing certificates with witnesses. 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 consistent. However, due to the large error of manual iden...

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
