Calibration system for simultaneous calibration of multiple motion capture elements

摘要

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.

1. A calibration system for simultaneous calibration of multiple motion capture elements comprising:
a motion element; a base coupled with said motion element wherein said motion element is configured to move in relation to said base; a mount coupled with said motion element and configured to hold a plurality of motion capture elements that comprise at least one sensor configured to capture any combination of one or more values associated with an orientation, position, velocity, acceleration of said plurality of motion capture elements; a computer configured to
sample motion from said plurality of motion capture elements when said mount is moved in or about or in and about at least one axis;calculate a calibration matrix for each of said plurality of motion capture elements to convert three axes motion capture data into calibrated motion capture data.
