Pattern Capture Range Structure

Abstract

A pattern image capturing range structure, which is mainly used to define the image capturing range on a carrier. On the aforementioned carrier, there are at least: a pattern area that can be patterns, characters, and symbols, and a bar code area. The bar code area There are a plurality of positioning parts located at least part of the corners of the barcode area, and at least one imaging range information part for interpretation and identification. This imaging range information part is used to generate a reference with at least the partial positioning part The image-capturing shape and relative size information extending to each peripheral side form an image-capturing range at least including the aforementioned pattern area.

Description

technical field [0001] The present invention relates to the structure of the image capturing range of a pattern, and in particular refers to a structure that is easy to identify and operate, can effectively simplify the image capturing procedure, and improve the overall pattern identifying efficiency. Background technique [0002] Fluorescent fiber image is an effective anti-counterfeiting label developed in recent years. It dyes fluorescent materials on chemical fiber carriers, and adds this fluorescent fiber to the chemical fiber carrier in a certain proportion during the papermaking process. Made from pulp. In the process of anti-counterfeiting label identification, the image sensor picks up the image containing the rectangular frame, and the area in the rectangular frame is the fluorescent fiber area, so the positioning and segmentation of the rectangular frame is the first step in identifying anti-counterfeiting information. Generally, there are two positioning methods...

Problems solved by technology

[0004] However, the above-mentioned positioning method still has complex judgment procedures and a large number of numerical calculations, which not only consumes the computing resources of the data processing unit, but also affects the efficiency of data processing, and is not economical in practical applications.

[0005] In the current application form, in addition to the anti-counterfeiting pattern and mark on the anti-counterfeiting label, there is also a structure showing a two-dimensional barcode, but the two-dimensional barcode is a logistics code for providing logistics (transportation, warehouse management) information , it has not been seen that the two-dimensional barcode (logistics code) has been given other functions related to imaging or graphic recognition
