A method for reading a code on a substrate by assembly of the code - fragments with the use of an imaging code reader

摘要

A method for reading a code on a substrate, wherein said code within a evaluation region on the substrate by at least two code fragments and the code is represented in each case at least two fragments at different positions within the evaluation area and from which are arranged on a base grid arranged code - elements are assigned to the damaged code and wherein from the evaluation area with an imaging code - reading device at least one digital image is produced and the at least one digital image in an image processing computer having a plurality of storage devices is evaluated, and a decoder for decoding of the signal is supplied to a code,characterized by the following process steps:1.1 The first with the code - reading device is generated digital image of the evaluation-range into a first memory of the image processing computer are read in,1.2 in the image processing computer, those image regions of the digital image which code fragments of the type of the required code, wherein a code fragments of different code types in the digital image is suppressed and the corresponding image regions of the further image processing are ignored, ..
