Tracking system calibration using object position and orientation

摘要

To calibrate a tracking system, a computing device receives positional data of a tracked object from an optical sensor as the object is pointed approximately toward the optical sensor. The computing device computes a first angle of the object with respect to an optical axis of the optical sensor using the received positional data. The computing device receives inertial data corresponding to the object, wherein a second angle of the object with respect to a plane normal to gravity can be computed from the inertial data. The computing device determines a pitch of the optical sensor using the first angle and the second angle.

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.
