Abstract
Three-dimensional human face identification card using micro lens array is proposed based on the introduction of integrated imaging technology into three-dimensional human face identification cards. The traditional ID card is a two-dimensional plane photograph. With the development of integrated imaging technology, each unit lens in the integrated imaging technology can record relative parts of information from various directions, combining a lenticular lens array and a concave lens array to realize naked eye in natural light you can see the three-dimensional photos on the ID card. This technology not only achieves visual three-dimensionality and beauty, but also enhances the security of identity cards, and can be widely applied to various situations requiring authentication.
