METHOD FOR PUNCHING AND CREATING/OUTPUTTING QR CODE LABEL AND METHOD FOR RECOGNIZING LABEL BY LIGHTING DIRECT/INDIRECT LIGHT SOURCE ON LABEL

摘要

PURPOSE: A method for punching and creating/outputting a QR(Quick Response) code label and a method for recognizing the label by lighting a direct/indirect light source on the label are provided to increase a recognition successful rate by using an inversion image creation technique of QR code, a label manufacturing technique, and an inverse QR code recognition technique simultaneously for being used in a factory or a storehouse including much dust and a process for injecting gas or liquid. CONSTITUTION: In a method for creating, recognizing, and reading an inverse QR code, a QR code created based on information to be created as a QR code is created into an inverse image. The created QR code is created into a QR code label inverse by selecting one material out of various kinds of metals, nonferrous metals, ceramics, plastics, and papers using a boring machine using a laser, a water jet, a drill, or a punch. The inverse QR code label is recognized and read using an indirect light source and a reflection plate. The inverse QR code label is recognized and read using a direct light source.
