1. A computer implemented method of calibrating a tracking system, comprising:

  • receiving positional data of a tracked object from an optical sensor by a computing device;

    computing a first angle of the object with respect to an optical axis of the optical sensor based on the received positional data;

    receiving inertial data corresponding to the object by the computing device;

    based on the inertial data, determining a second angle of an orientation of the object with respect to a plane normal to gravity; and

    in response to a calibrate command from a user, determining a pitch of the optical sensor based on both the computed first angle and the determined second angle.
