Research on 3D Visualization of Underground Antique Tomb Based on Augmented Reality

This paper researches on 3D visualization of underground antique tomb based on Augmented Reality .At first,this paper established 3D model of antique tomb with OpenGL in VC++6.0. In order to establish augmented reality 3D model of antique tomb, the OpenGL model of antique tomb was transferred into ARToolKit and realized 3D augmented reality visualization in ARToolKit. As ARToolKit uses computer vision techniques to calculate the real camera position and orientation relative to marked cards,so it is difficult to provide AR applications in outdoor environment. At last, this paper puts forth a new method to allow ARtoolkit to receive the data of GPS and 3D electronic compass, so it can make 3D registration with both computer vision and sensors.
