Abstract: In order to enhance the accuracy of the registration in large range Augmented Reality(AR) system, the reasons which causes the error of linear interpolation in grids are analyzed, and a calibration approach combined with inverse distance weighting is proposed. The new approach improves the search strategy and interpolation algorithm of original method. It discusses the possibility of double transmitters cooperation, and proposes a solution. Experimental results show that registration solution of double transmitters can extent AR system working and interaction range effectively.
