An inertial frame of reference can be defined in analytical terms as a frame of reference that describes time and space homogeneously. The potential of inertial measurement units imus for ergonomics applications appears promising.

Inertial measurement units body. Validation of inertial measurement units with an optoelectronic system for whole body motion analysis. However previous imus validation studies have been incom validation of inertial measurement units with an optoelectronic system for whole body motion analysis springerlink. Roll pitch and yaw. Authors are encouraged to submit articles dealing with filtering techniques and signal treatment procedures for imus signals as well as applications in clinical and sports related scenarios. An inertial frame of reference in classical physics and special relativity possesses the property that in this frame of reference a body with zero net force acting upon it does not accelerate. Some imus also include a magnetome ter which is commonly used as a heading reference.
An inertial measurement unit also known as imu is an electronic device that measures and reports acceleration orientation angular rates and other gravitational forcesit is composed of 3 accelerometers 3 gyroscopes and depending on the heading requirement 3 magnetometers. An inertial measurement unit imu is an electronic device that measures and reports a bodys specific force angular rate and sometimes the orientation of the body using a combination of accelerometers gyroscopes and sometimes magnetometersimus are typically used to maneuver aircraft an attitude and heading reference system including unmanned aerial vehicles uavs among many others. Most people interact with these devices daily via the imu in their smartphone that. That is such a body is at rest or moving at a constant velocity. It works by detecting linear acceleration using accelerometers and rotational rate us ing gyroscopes. Med biol eng comput.
That is to say one per axis for each of the three vehicle axes. Inertial measurement unit a sensor consisting of a three axial accelerometer and a three axial gyroscope approximately mounted in one point is called an inertial measurement unit imu. Epub 2017 jun 26. This special issue encourages the submission of original research articles presenting novel techniques and applications of inertial measurement units in the area of movement analysis. Validation of inertial measurement units for upper body kinematics. Epub 2016 jul 5.
In theory a calibrated imu measures 3d angular velocity and 3d acceleration and gravity with respect to the sensor housing. Inertial measurement unit imu sensors are electronic devices that measure and report a bodys specific force angular rate and sometimes the magnetic field surrounding the body using a combination of accelerometers gyroscopes and magnetometers. An inertial measurement unit imu is an electronic de vice that measures and reports a bodys specific force angular rate and orientation.
