Novel method to measure track irregularity based on multiple MEMS-IMU and geometric constraint

Abstract The track regularity with high accuracy is crucial important to protect the dynamic safety in high speed and heavy haul railways, normally, the inertial measurement unit (IMU)is capable to provide the precise solution for track irregularity measurement. However, to achieve high accuracy, th...
