RepoIMU repository is proposed for the needs of algorithm testing on the basis of the output of IMU sensors (accelerometer, magnetometer and gyroscope). Quaternion coded data from optical motion capture system (Vicon Nexus) are used as a reference. Although data are from two different systems, they were synchronized and properly cropped for the sake of user’s convenience.

Repository features:

– signals from IMU sensors (accelerometer, magnetometer, gyroscope) synchronized with reference orientation quaternion from optical motion capture system;

– data from two kinematic sets: wand (T-stick) and 3-segment pendulum;

– a full range of orientation angles’ changes;

– recording with different acceleration values.

repoimu's Issues

Magnetic reference / dip

Please tell us what the magnetic reference at which magnetometer readings were recorded.

EULER ANGLES IN REPOIMU

Dear colleagues, please tell us, how to calculate Euler angles from quaternion in RepoIMU datasets? May be you have some MATLAB script?
