A Survey of ARToolkitBased Augmented Reality Applications

Augumented Reality is a budding area in virtual reality research , which tends to present a combination of real and virtual image to the user. This paper briefs a short survey on Augmented Reality applications that uses ARToolkit . Augmented Reality is one of the research hotspots of many renowned foreign universities and research institutions in recent years. AR technology has a wide range of applications like Advertisement, Navigation, Medical, Military, Architecture and Games. Libraries are needed for developing Augmented Reality applications. ARToolKit is one among the poineer software libraries for building Augmented Reality (AR) applications. One of the key difficulties in developing Augmented Reality applications is the problem of tracking the user’s viewpoint. ARToolKit is resilient to the above described problem by the use of computer vision algorithms. The ARToolKit video tracking libraries calculate the real camera position and orientation relative to physical markers in real time. This enables an easy development of wide range of Augmented Reality applications.
