METHOD AND APPARATUS FOR CORRECTION OF NONLINEAR FIELD OF VIEW DISTORTION OF DIGITAL IMAGING SYSTEM

摘要

PROBLEM TO BE SOLVED: To quantify nonlinear distortions of imaging optics within a computer vision system as corrective values within a viewing window defined by a pixel array.;SOLUTION: A test artifact 16 is displaced within an object plane 44 through increments of measured distances and the corresponding displacements of the test artifact 16 within an image plane are recorded within the pixel array. Comparisons are made between the actual appearances of the test artifact 16 within the image plane and predicted appearances of the test artifact within the image plane based on the measured displacements on the object plane for determining the corrective values.;COPYRIGHT: (C)2006,JPO&NCIPI
