ABSTRACT:
An apparatus for correcting an inertial sensor includes an inertial sensor module, a storage module and a control module. The inertial sensor module measures angular velocity and acceleration of an object moving in a space. The storage module stores predetermined operation information and parameters required to correct the measured acceleration. The control module calculates motion velocity from the measured acceleration using the operation information and the parameters, and corrects the calculated motion velocity for each interval between zero-angular-velocity time instances at which angular velocity about an arbitrary axis is “0”.
