An anti-dazzle certificate automatic reading system and method

Abstract

The invention discloses an anti-dazzle certificate automatic reading system which comprises a light source, a light source control unit, an image acquisition unit and an image processing unit. The light sources comprise a left light source (11) and a right light source (12), the left light source (11) obliquely irradiates the surface of the certificate (10) rightwards, and the right light source (12) obliquely irradiates the surface of the certificate (10) leftwards; The light source control unit controls opening and closing of the light source independently; The image acquisition unit is usedfor acquiring two images of the certificate (10) when the left light source (11) and the right light source (12) are turned on respectively; and the image processing unit is used for selecting the right half side of the certificate image collected when the left light source (11) is turned on and the left half side of the certificate image collected when the right light source (12) is turned on, and splicing and combining the right half side and the left half side to obtain a complete glare-free image. Therefore, the problem of dazzle interference is solved, high-quality, readable and recognizable certificate images can be obtained, and correct inspection can be carried out.

Description

technical field [0001] The invention belongs to the field of certificate anti-counterfeiting and identification, and in particular relates to an automatic reading system and method for anti-glare certificates. Background technique [0002] With the rapid development of my country's economy and the advancement of reform and opening up, the flow of personnel at home and abroad has increased year by year. This growth has created enormous challenges for institutions such as railway stations, airports, and customs. [0003] In the past, the verification of the certificates of floating personnel was mainly completed through manual verification. Due to the uneven professional level of the staff, it has brought huge hidden dangers to related work. So all kinds of document automatic inspection systems came into being, and achieved good results. [0004] However, with the development of anti-counterfeiting technology, various new materials are used in the anti-counterfeiting coating...

AI Technical Summary

Problems solved by technology

This coating can improve the anti-counterfeiting performance of the document, but its unique glare will also seriously interfere with the collection and reading of text and patterns, affect the performance of the automatic inspection system, and cause the system to produce false inspections

For example, the passport automatic inspection technology mentioned in the patent No. CN101661644A titled "Passport and Document Automatic Inspection Technology" ignores the treatment of glare, and it is difficult to obtain better image quality for documents with anti-counterfeiting coatings.
