Paper Abstract

The traditional tabletop AR systems general use head mounted display (HMD) that has some shortcomings, such as the imprecise precision and low flexibility. To solve these problems, a new design of video see-through tabletop system is presented. In this paper, we describe an outline of the system and the registration algorithms for the system. A system origin calibration algorithm is proposed. In the calibration experiment, a sign cube is introduced for the first shooting of the camera. The position of the sign cube becomes the origin of the world reference frame, in which the translation and rotation of the virtual objects relative to the origin can be calculated easily. The experimental results show that the video see-through tabletop system meets the precision and flexibility requirements very well.
