Method and device for face recognition technology applied to witness consistency test

Abstract

A method and device for applying face recognition technology to identity verification of witnesses, wherein the method includes the following steps: (1) setting the original similarity score and comparison threshold; (2) acquiring and extracting ID card information ;(21) Acquisition of ID card information; (22) Extraction of ID card information; (3) Collection, processing and extraction of the face image of the card holder; (31) Collection of face image of the card holder; (32) Processing of the face image of the pass holder; (33) extraction of the face image of the pass holder; (4) information comparison between the ID card information and the face image of the pass holder; (41) comparison and calculation of scores; (5) Processing of comparison results; therefore, the present invention has the advantages of faster inspection speed, higher inspection accuracy, and higher inspection efficiency.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a method and a device for applying face recognition technology to the consistency check of witnesses. Background technique [0002] In daily life, for the safety of the people, the stability of the society, and the convenience of managing the personal information of citizens, there are many scenarios that require ID card inspection; the direct purpose of ID card inspection is mainly three: to identify the authenticity of the documents, to identify the identity of the documents and The consistency of the holder (also known as the consistency of witnesses), and the identification of blacklist ID cards, so that the staff of the public security department can pick out fake ID cards, fake ID cards, and blacklist ID cards to prevent lawbreakers Use forged false ID cards or other people's ID cards to do things that are detrimental to the interests of society and others. In the...

Problems solved by technology

[0003] However, a face recognition method and a face recognition device based on an identity document in the above-mentioned prior art, due to the influence of the following factors, make this face recognition method have relatively large errors in the consistency check of witnesses: First, as we all know, the width of the built-in photo of the ID card is only 102 pixels, which is not clear, and there is a problem of loss or distortion of some facial feature information; while the face photo taken by the acquisition device has relatively large pixels and is relatively clear, so , the face feature information in the face photos taken by the acquisition device will be relatively rich or accurate. In this way, there will be a large difference in face feature information between the built-in photo of the ID card and the face photo taken by the acquisition device. , and the difference in facial feature information between the two photos will interfere with face recognition, affecting the accuracy of consistent recognition of witnesses

Second, the shooting time of the photo of the ID card is often earlier than the recognition time of the consistency of the bearer's identity card, that is, there is a relatively large time difference between the face photos taken by the acquisition equipment when the recognition of the identity card is consistent with the identity card, while the photo The difference in shooting time will inevitably bring about subtle changes in facial features, which will also cause differences in facial feature information between the face feature information of the ID card photo and the face feature information in the face photos taken by the acquisition device, and will also Affects the accuracy of consistent recognition of witnesses and witnesses, and ultimately leads to low efficiency of consistent recognition of witnesses and witnesses
