SMART DISPLAY: A MOBILE SELF-ADAPTIVE PROJECTOR-CAMERA SYSTEM
Tien Ju Yang, Yi Min Tsai, Liang Gee ChenAbstract
Owing to the diversity of projection surfaces, an effective mobile display system must be adaptive to the surface to avoid introducing a clipped scene. In this paper, we propose a smart mobile display system which automatically adapts to the location and motion of a surface. Firstly, an imperceptible structured light technique is adopted and continuous adaptation is accomplished. Secondly, a specifically designed code image with high distortion tolerance is proposed. Thirdly, we present a priority-based correction method to revise previous decoding results. Finally, a matching procedure resisting noise interruption is introduced. The system achieves 95% correct rate under the common indoor illuminance. In addition, the system performance is independent of the projected content and the surface shapes.
