Obtaining Displacement Information Based on Integration Filter
Kun Hu · Yibiao jishu yu chuanganqi · 2012
Displacement information was got from the acceleration signals by the second-order integration filter.The simulation signal was used to verify the correctness of the algorithm,and the experimental cost was reduced by the method.In order to improve the stability and the anti-noise ability of the system,the acceleration was processed by removing the average and wavelet transform before integration.Finally,the acceleration was measured by the inertial measurement unit XW-IMU5250 and more precise displacement data can be acquired from the algorithm.
