dc.description.abstract | This paper presents a calibration method for
consumer-grade accelerometers, gyroscopes, and magnetometers.
Considering the calibration of consumer-grade sensors, it is
essential that no specialized equipment is required to create
reference signals. In addition, the less is required from the
reference signals, the more suitable the method is on the field.
In the proposed method, the novelty in the calibration of
the gyroscopes lies in the exploitation of only the known net
rotations between the positions in a multi-position calibration.
For accelerometers and magnetometers, the innovation is that
the direction of reference signals, the gravity and the magnetic
field of the Earth, are estimated with calibration parameters. As
a consequence, no precise absolute alignment of the sensors is
needed in the calibration. The rotations need not be done about
a constant axis. In the proposed method, the biases, scale factors,
misalignments, and cross-coupling errors for all the sensors
as well as hard iron and soft iron effect for magnetometers
were modelled. In addition, the drift of the sensors during
the calibration was estimated. As a result, all the sensors were
calibrated at once to the same frame, exploiting only a cube and
a jig and thus, the method is eligible in the field. To estimate the
quality of the calibration results, 95 % confidence intervals were
calculated for the calibration parameters. Simulations were done
to indicate that the calibration method is unbiased. | |
