data

This data set contains data from a sacrum mounted 6 degree of freedom inertial sensor from 4 horses in trot.Each data sheet contains the original acceleration, rate of turn and magnetic field data as well as integrated data following the method described in Pfau et al 2005. 10 different versions of the data set are contained in each Excel file: one sheet per sample rate. 100: original sample rate, 50, 45, 40,35, 30, 25, 20, 15, 10, 8: downsampled to 50 (45 ...) Hz (with built-in Matlab function taking into account anti-aliasing filters and then upsampled again to 100 Hz for the subsequent integration process (Pfau et al, 2005).Column headers:Acc_X, Acc_Y, Acc_Z: tri-axial acceleration in sensor reference frameGyr_X, Gyr_Y, Gyr_Z: tri-axial rate of turn data in sensor reference frameMag_X, Mag_Y, Mag_Z: tri-axial magentic field data in sensor reference frameRoll, Pitch, Yaw: Euler angles in world AccRotX, AccRotY, AccRotZ: acceleration rotated into horse based systemVeloRotX, VeloRotY, VeloRptZ: velocities integrated from rotated accelerationsDospRotX, DispRotY, DispRotZ: displacements integrated from rotated velocities<br><br>Pfau, T., Witte, T.H. and Wilson, A.M.
