Abstract
Sand table technology has a great prospect in wide fields. However, sand table technology is mainly based on two-dimension (2D) display. Based on 3D display and head-tracking technique, a novel 3D sand table technology is proposed. The technology consists of a 3D display module, a head-tracking module and an image processing module. The head-tracking module can track the position of observer's head closing to the center of eyes. According to the position, the image processing module would modify the projection matrix of virtual cameras. 3D virtual scene rendered by the image processing module would be display as if floating upon the projection screen in the display module. An experimental system for the 3D sand table was demonstrated, which offers the observer great field of view (FOV) to watch immersive 3D virtual scene.
