The study and improvement of Augmented reality based on feature matching

Augmented reality is an emerging technology of Virtual Reality, which has a great development and application prospects. Augmented Reality involves knowledge about sensors, image recognition, computer vision, human-computer interaction, virtual reality, and many other areas. The key technologies include displaying, registration and tracking, interactive etc. Among them, registration and tracking is the most important technology. In Augmented reality system, the traditional methods of registration and tracking technology has the problems of not accurate, low efficient. In this paper, improved feature matching algorithm is used in augmented reality system. Experimental results show that, compared with traditional methods, improved algorithm can significantly improve the efficiency of registration and tracking.
