Abstract
A novel self-calibrating sensing technology using
miniature linear encoders and Inertial/magnetic Measurement
Unit (IMU) provides the accuracy, fast response and robustness
required by many body motion processing applications. Our
sensor unit consists of an accelerometer, a 3-axis magnetic
sensor, 2 gyroscopes and a miniature linear encoder. The fusion
of data from the sensors is accomplished by extracting the
gravity related term from the accelerometer and consistently
calibrating the gyroscopes and linear encoder when the sensor
unit is under static conditions. Using the fused sensors, we
developed a complete motion processing system that consists of
a gateway where the human kinematics modeling is embedded.
A time divided multiple access wireless architecture is adopted
to synchronize the sensor network at 100Hz. Experimental
results show that the combination of the IMU and linear
encoder produces a low RMS error of 3.5° and correlation
coefficient of 99.01%. A video showing the capture a
performer’s upper body motion is also realized.
