| Abstract: | A rigorous calibration model of inclinometer in TBM (Tunnel Boring Machine) was derived. The two axis angle data collected by the inclinometer was considered as point clouds of a plane, and a method of robust estimation was derived. On the basis of the above model and method, a rigorous combined model was proposed to solve the Fusion data of prism and inclinometer by using the method of least square collocation. Finally, the above model and method were analyzed and verified by experiment, and the results showed that the proposed model of shield configuration is feasible. |
