Abstract
A method and apparatus for calibrating a set of transducers. In one illustrative embodiment, an apparatus comprises a target device, an imaging device, and a calibrator. The imaging device generates a plurality of images of a target formed by the target device as the target device is rotated relative to the imaging device about a pivot axis formed at an interface between a first structure and a second structure in response to the first structure being rotated about the pivot axis relative to the second structure. The calibrator identifies a plurality of angles of the target about the pivot axis using the plurality of images. The calibrator further identifies calibration information using the plurality of angles.

An apparatus comprising:
- a target device;
- an imaging device that generates a plurality of images of a target formed by the target device as the target device is rotated relative to the imaging device about a pivot axis formed at an interface between a first structure and a second structure in response to the first structure being rotated about the pivot axis relative to the second structure;
- and
- a calibrator that identifies a plurality of angles of the target about the pivot axis using the plurality of images and identifies calibration information using the plurality of angles.
A calibration system comprising:
- a number of target devices;
- a number of imaging devices in which an imaging device in the number of imaging devices generates a plurality of images of a target formed by a corresponding target device in the number of target devices as the corresponding target device is rotated relative to the imaging device about a pivot axis formed at an interface between a first structure and a second structure in response to the first structure being rotated about the pivot axis relative to the second structure;
- a set of transducers that measure rotation of the first structure about the pivot axis relative to the second structure to generate output data;
- and
- a calibrator that identifies a plurality of angles about the pivot axis for the target using the plurality of images and identifies calibration information using the plurality of angles in which the calibration information is used to convert the output data into angular data in desired angular units.
