| 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. |

| Keywords: | Augmented Reality(AR) magnetic tracing correction linear interpolation spatial interpolation double transmitters |
