IMAGE DISTORTION COMPENSATION METHOD BY A LENS AND A MIRROR, PARTICULARLY FOR REDUCING THE TIME NECESSARY FOR IMAGE DISTORTION COMPENSATION

摘要

PURPOSE: An image distortion compensation method by a lens and a mirror are provided to reduce the error rate caused by component recognition by correcting a distorted image through a camera lens and a mirror.;CONSTITUTION: The center of each point of an image grid glass is calculated(S20), and the sum of the scalars of an image normal vector and a top normal vector is calculated(S30). A distortion angle of the image grid glass is calculated(S40), and the non-linear higher dimensional functions(f,g) of vertical and horizontal column groups for the image and top grind glasses are respectively calculated(S50). Through a high level function, the function for width and height is calculated(S60). Location compensation, depending on a compensation table, is performed(S80).;COPYRIGHT KIPO 2011
