چکیده
2.1 Principles of Inertial Sensors A coordinate system must be defined prior to deployment of an inertial sensor for body motion measurement. If the origin of a moving coordinate system has acceleration (A0) and rotates with a gyroscopic angular velocity (ω), and if a mass (m) has the position vector (r0) and the velocity (u0) with respect to the moving coordinate system, then the inertial force observed is mA0 52mA0 1 2mu0 3ω1mω3 ðr0 3ωÞ1mr0 3 dω dt (1)

متن کامل3d Measurement of Lower Limb Kinematics in Alpine Ski Racing Using Inertial Sensors
INTRODUCTION: In alpine skiing monitoring the 3D segment kinematics is crucial to better understanding the injury risk factors and performance aspects. 3D camcorders have been primarily used to evaluate segment kinematics. While these systems allow valid measurement, their complexity limits their use to research applications. Alternatively, wearable systems fusing inertial measurement units (IM...
