Abstract: We describe an auto-calibrated 3D perspective-corrected spherical display that uses multiple rear projected pico-projectors. The display system is auto-calibrated via 3D reconstruction of each projected pixel on the display using a single inexpensive camera. With the automatic calibration, the multiple-projector system supports a seamless blended imagery on the spherical screen. Furthermore, we incorporate head tracking with the display to present 3D content with motion parallax by rendering perspective-corrected images based on the viewpoint. To show the effectiveness of this design, we implemented a view-dependent application that allows walk-around visualization from all angles for a single head-tracked user. We also implemented a view-independent application that supports a wall-papered rendering for multi-user viewing. Thus, both view-dependent 3D VR content and spherical 2D content, such as a globe, can be easily experienced with this display.
