| Abstract: | Integration of multi-sensors is an effective method to accomplish train positioning precisely and reliably.Aiming at the problem that wearing of train wheels leads to decrease of wheel diameters and damage to the positioning precision of the odometer in the integrated train positioning system,the error characteristic of the odometer in integrated train positioning is analyzed.A novel wheel diameter calibration method is proposed by use of GPS and the inertial sensor aided wheel diameter calibration method o... |
