Patent ID: 8223208

Claim:
A method for determining a parameterization of the optical characteristics of an imaging device, the imaging device comprising at least one projection unit and at least one camera being under synchronized dynamic optical control; the method comprising performing the steps of: (a) positioning a calibration object at a focal plane at a distance of a plurality of distances from the imaging device; (b) aligning the calibration object at said focal plane with the imaging device; (c) projecting a pattern onto the calibration object at said focal plane; (d) detecting features of the pattern; and (e) using the detected locations of the features to calibrate elements of the imaging device to determine a set of calibration parameters for said focal plane; and repeating steps (a)-(e) for each focal plane at each of the other distances of the plurality of distances from the imaging device, wherein the performing and the repeating occur within a single calibration session.
