Screen image linkage comparison method

Abstract

A screen image linking-up mapping method is provided, which includes first performing a matching process to a plurality of patterns to be recognized and sending the same to a terminal device; performing a determination step of "whether to use a complete pattern to perform comparison or not"; if the determination result is positive "Y", forming a plurality of independent preview frames on a predetermined display screen of the terminal device and respectively placing each pattern to be recognized with the same size and arrangement direction in each independent preview frame for allowing the operator to easily perform a complete pattern comparison; and if the determination result is negative "N", forming a complete preview frame and at least two local preview frames on the predetermined display screen of the terminal device, selecting one pattern from the plurality of patterns for use as a standard pattern, and placing the standard pattern in the complete preview frame, so that the local preview frame can display the magnified pattern of each pattern corresponding to the same local part on the standard pattern. The method is easy to manipulate and may improve the accuracy of the comparision result.

Description

technical field [0001] The invention relates to a screen-based image linkage comparison method, in particular to an image linkage comparison method with convenient operation and easy comparison. Background technique [0002] In order to combat counterfeiting, countries around the world have continuously developed various anti-counterfeiting technology products. At present, the most common application is to attach an anti-counterfeiting label (such as anti-counterfeiting paper, special printing and laser labels, etc.) Original products can form a basic distinction from counterfeit products; however, with the improvement of counterfeiting technology, imitations of the above-mentioned anti-counterfeit labels are emerging in an endless stream. At the same time, an inquiry serial number and an inquiry channel (telephone or fax number) information are displayed for consumers to use communication tools (telephone, fax machine) to contact, and obtain anti-counterfeiting (voice, fax)...

AI Technical Summary

Problems solved by technology

[0006] 1. When consumers compare structural textures and images, their eyesight needs to switch between the information carrier and the image file to be queried, which is not only complicated and time-consuming, but also increases the burden on consumers’ eyes, and also affects the query speed

[0007] 2. Due to the low resolution of the general query image files, it is impossible to make a fine comparison. As long as the counterfeiters achieve an approximate effect on the shape and position of the anti-counterfeit texture, it will be difficult for consumers to identify, and there is no other solution

[0008] 3. Due to the insufficient identification and disclosure of the position and characteristic information of the structural texture, it is impossible to make a fine comparison. As long as the counterfeiter reaches the information description on the anti-counterfeiting shape and position of the texture, consumers will recognize the fake as real
