Abstract

The invention belongs to the mobile augmented reality (MAR) technology field and provides a mobile augmented reality type card identification method based on mirror reflection. The method comprises steps of (1), mirror reflection design, including foundation, reflective mirror casing and reflective mirror design; (2), registration picture design; (3), card design facing mobile terminal adaption; and (4), orthophoto correction of an acquired image. The method is advantaged in that through a specially-designed reflector device, in combination with the image correction technology, a card in front of a bottom portion of a mobile terminal is accurately mapped to a screen, a problem that card scanning and children hand constraint are carried out during equipment holding existing in a traditional AR identification method is solved, moreover, a problem of low identification efficiency caused by a deformed image acquired by a front camera in the traditional identification method can be effectively solved through orthophoto correction of the acquired image.

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 ...
