Abstract:Space-time consistency is of great importance for mapping things from physical world to cyber world, which could be one of the fundamental issues in constructing cyber-physical system (CPS). A two-dimensional code spatiotemporal modeling method is proposed in this paper. We apply the two-dimensional code as an information carrier to store object's characteristics (object's ID, attributes, instructions, spatiotemporal data, etc.), the smartphone as a mobile device to obtain the object's real-time spatiotemporal… Show more
