Abstract

The invention belongs to the technical field of mobile augmented reality, and provides a mirror reflection-based mobile augmented reality card identification method, comprising: (1) mirror reflection design, including a base, a mirror housing, and a mirror design. (2) The design of the registration picture. (3) Card design for mobile terminal adaptation. (4) Orthorectification of acquired images. The present invention uses a specially designed reflector device, combined with image correction technology, to correctly map the card at the front of the bottom of the mobile terminal to the screen, and the reflector device effectively solves the problem of needing a hand-held device to scan the card and restrain children's hands in traditional AR recognition . At the same time, the orthorectification of the captured image effectively overcomes the problem of low recognition efficiency caused by the deformation of the image captured by the front camera in traditional recognition.

Description

technical field [0001] The invention belongs to the technical field of mobile augmented reality (Augmented Reality, AR), and more particularly relates to a mobile augmented reality card recognition method based on mirror reflection. Background technique [0002] Augmented reality is a branch of the development of the field of virtual reality, and it is also a brand-new research field where various technologies such as computer vision, computer graphics, multimedia, and human-computer interaction intersect and can realize the seamless connection between the real world and the virtual world. Using the feature of combining virtual and real, realize the interaction inside and outside the mobile terminal screen, and exercise children's hands-on ability; from the form of expression, it can enhance children's interest in things, and explore and study deeper content in an interactive way. With the improvement of the computing power of mobile terminals, the integrated use of various ...
