Nonlinear distortions of imaging optics within a computer vision system
are quantified as corrective values within a viewing window defined by a
pixel array. A test artifact is displaced within an object plane through
increments of measured distances and the corresponding displacements of
the test artifact within an image plane are recorded within the pixel
array. Comparisons are made between the actual appearances of the test
artifact within the image plane and predicted appearances of the test
artifact within the image plane based on the measured displacements in
the object plane for determining the corrective values.
