Zusammenfassung:A machine motion trajectory measuring apparatus includes a three-axis acceleration sensor measuring acceleration of a motion-trajectory measurement subject and outputting the result as an acceleration sensor signal, a sensor signal separation unit separating the acceleration sensor signal into two or more frequency bands, a motor signal separation unit separating a detection position signal into the frequency bands identical to those of the sensor signal separation unit, a data calibration unit calibrating the acceleration sensor signal in each of the two or more frequency bands by using the acceleration sensor signal separated by the sensor signal separation unit and the detection position signal separated by the motor signal separation unit and obtaining a motion trajectory component in each of the two or more frequency bands, and a motion trajectory calculation unit coupling the motion trajectory components in the two or more frequency bands and outputting the result as a motion trajectory.
