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 ... [Show full abstract] 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.
