A method and apparatus for calibrating a set of transducers (120). In one illustrative embodiment, an apparatus comprises a target device (137), an imaging device (139), and a calibrator (136). The imaging device (139) generates a plurality of images (140) of a target (138) formed by the target device (137) as the target device (137) is rotated relative to the imaging device (139) about a pivot axis (115) formed at an interface (113) between a first structure (110) and a second structure (112) in response to the first structure (110) being rotated about the pivot axis (115) relative to the second structure (112). The calibrator (136) identifies a plurality of angles (142) of the target (138) about the pivot axis (115) using the plurality of images (140). The calibrator (136) further identifies calibration information (130) using the plurality of angles (142). |
