Abstract

The invention discloses a three-dimensional identity card and a preparation method thereof. The three-dimensional identity card comprises two contents, namely a three-dimensional identity photo, that is, the photo on the identity card is three-dimensional, and a three-dimensional human face image can be seen, and electronic information stored in the identity card for recording the three-dimensional data of a human face, which is recorded and loaded onto an electronic chip in the identity card when the identity photo is photographed; and in operation, a detecting camera can obtain the three-dimensional human face information of a user and judges whether the user is the owner of the original identity card. The three-dimensional identity card is a next-generation identity display and recognition technology, and is to be widely applied to citizen identity authentication; and the three-dimensional identity is necessary in various fields such as customs and airport security check, public security, banking password, computer confidential login and staff identity authentication.

Description

Technical field

[0001] The invention relates to an ID card, in particular to a three-dimensional ID card and a preparation method thereof. The ID card has a three-dimensional photo and internally stored three-dimensional photo information. technical background

[0002] The ID card is a document widely used to identify people's identities. At present, the photo on the ID card is a two-dimensional photo with no three-dimensional effect. It not only lacks vividness and interest, but also when used, it may not be correctly recognized under conditions such as camouflage only by visual observation.

[0003] The current two-dimensional face recognition technology usually makes judgments based on the facial features and the distance between them. However, when the angle between the face and the camera changes, the distance between the facial features changes, which may cause errors. Sentenced. Therefore, the development of a new generation of 3D ID card technology is of great significanc...
