Gyroscope

Revision as of 13:13, 19 September 2017 by CHI (Talk | contribs) (Characteristics)

Physicall the Gyroscope measures the rotational velocity on three axis. By integra-tion the orientation change since the last update can be calculated. Consequently the Gyroscope can´t provide absolute orientation, but is able to propagate the orientation once it is initialized.

Characteristics

  • Provides orientation in world coordinates once it is initialized by another orientation estimation system (e.g. AR-Marker or Compass)
  • The orientation can be propagated accurately, characterized by a growing er-ror of 0.05° per second.
  • Very low standard deviation.
  • The orientation is updated with roughly 250Hz.
  • Very fast and responsive.
  • Requires a Gyroscope sensor.
