Abstract:
A calibration system for simultaneous calibration of multiple motion capture elements (MCEs) of at least one type (accelerometer and/or gyroscope). Includes motion and/or rotational element coupled to a base and configured to move and/or rotate multiple MCEs mounted on a mount in and/or about at least one axis. For one axis movement embodiments, after each motion and/or axial rotation, the motion and/or rotational mount itself is rotated for example manually, so the mount points in a different direction, i.e., the Z axis. In a single axis embodiment, this is performed twice so that each axis of the MCEs experience motion and/or rotation about three axes. The motion capture data is sampled and used in calculation of a 3×3 calibration matrix. The physical format of the motion capture sensors may be any format including chip, memory or SIM card format, PCB format, mobile computers/phones.
