Claim 7:
8. A method for camera focus alignment of a lens, comprising:
defining a plurality of omni-symmetrical regions within the lens;
defining a localized set of calibration parameters for each of the plurality of omni-symmetrical regions;
defining a field of view of the lens as a union of the fields of view of each of the plurality of omni-symmetrical regions;
setting one or more focus station parameters;
placing a camera and the lens in the focus station;
capturing images via the camera and lens;
estimating the intrinsic parameters for each of the plurality of omni-symmetrical regions;
estimating the extrinsic multi-camera parameters, including one or more portions thereof able to resolve different resolutions of an object being imaged, for each of the plurality of omni-symmetrical regions;
evaluating the results of application of the intrinsic parameters and defining one or more adjustments to be made to the parameters of the camera and lens in the focus station; and sending the adjustments to the focus station.
