Abstract: A method for correcting a position error for a motion terminal driven by a driving component may include obtaining a first displacement of the motion terminal acquired by a first sensor associated with the driving component. The method may also include obtaining a second displacement of the motion terminal acquired by a second sensor associated with the motion terminal. The method may further include determining an offset value based on a difference between the first displacement and the second displacement. The method may include determining a calibration displacement value relating to the first displacement based on the offset value.
