Abstract

The invention discloses calibration paper of a multiple-linear-array charge coupled device (CCD) scanning system and an adjusting method and relates to the field of machine vision. The calibration paper comprises collinear calibration paper. A dotted line is arranged on the collinear calibration paper, the accuracy of the dotted line is equal to the minimum accuracy required by CCD acquisition, and the size of dots of the dotted line is identical to the size of a minimum pixel acquired by a CCD. Corresponding patterns can be printed on common paper to manufacture the calibration paper, the multiple-linear-array CCD scanning system can be conveniently adjusted by using the calibration paper, the calibration paper cost is effectively reduced, and adjusting steps are simplified.

Description

technical field [0001] The invention relates to the technical field of machine vision, in particular to a calibration paper and an adjustment method for a multi-line array CCD scanning system. Background technique [0002] Machine vision mainly uses computers to simulate human visual functions, extracts information from images of objective things for processing and understanding, and is finally used for actual detection and control. This technology can be widely applied to the quality inspection of printed matter, food, fruits and vegetables, electronic devices, automobiles and environmental protection green energy, etc., replacing manual inspection, reducing costs, and improving inspection speed and accuracy. [0003] There are two types of traditional wired array CCD and area array CCD in camera selection. Among them, the advantages of the linear array CCD are: the uniformity of the illumination source of the linear array CCD is easy to correct; the linear array CCD can a...
