Development of real-time markerless augmented reality system using multi-thread design patterns

Abstract

In the field of augmented reality (AR) technology, recently, several studies have been conducted on the real-time operation of a markerless AR system. However, this system has higher computational complexity than a marker-based system. This study proposes a method to implement a real-time markerless AR system using the speeded up robust features (SURF) extraction algorithm and a tracking algorithm based on multi-thread design patterns. Further, a method to quickly identify and execute reference objects even in the case of multiple reference objects is proposed. Single-thread and multi-thread systems are compared, and the performance of the implementation methodology proposed in this study is verified through a performance analysis depending on whether or not the finder thread added to search the reference objects is used. © 2011 Springer-Verlag.
