Application Research of two-dimensional code in mobile augmented reality

Augmented Reality (AR) is an emerging technology that adds computer-generated virtual information to real-world scenarios, thereby enhancing people's understanding of the surrounding real-world environment. With the development of network, augmented reality technology is gradually applied to mobile devices based on smart phones. Augmented reality technology has been widely used in foreign cultural circles, such as ancient architecture research, Museum exhibitions, enhanced travel and campus navigation. At present, our country's mobile augmented reality technology can only aim at a small number of targets, and can not meet the needs of target recognition and tracking for mobile users. On this basis, two-dimensional code is gradually developed in the mobile augmented reality system. A large number of two-dimensional code content coding technology and fast positioning technology can meet the needs of people. Target recognition requirements. Therefore, this paper expounds the general situation of two-dimensional code and mobile augmented reality technology, studies the application of two- dimensional code in mobile augmented reality, and points out its application in library.
