Multifunctional certificate information collection system

Abstract

The invention discloses a multifunctional certificate information collection system, which is applied to various types of certificate information. The collection system comprises an image collection module, an image processing module and an image information extracting module, wherein, the image collection module is used for obtaining certificate image information, the image processing module is used for processing the certificate image so as to output images conforming to requirements, and the image information extracting module is used for extracting the written information of the certificate image. The image collection module comprises a CMOS image collection module, a transmitting interface module, an LED light source group module and a power supply module; the image processing modulecomprises a color cast calibration unit, a barrel distortion calibration unit, a tilting and inversion calibration unit and a certificate information division unit; the image information extracting module utilizes the OCR technology to extract the written information of the certificate image. The CMOS image collecting module of the invention adopts a fish-eye-lens to miniaturize equipment; the image processing module can quickly and accurately solve the problems of color cast, barrel distortion, tilting, inversion and certificate information division, provides higher using freedom for users and ensures more accurate image division.

Description

technical field [0001] The present invention relates to a multifunctional certificate information collection system applied to various certificate information, in particular to a certificate information collection system integrating functions such as certificate image collection, image processing, and image information extraction. Background technique [0002] In many fields of social and people's livelihood, it is often necessary to obtain relevant information from certificates. With the maturity of computer technology, image processing and optical character recognition algorithms, it has become possible to use computers to automatically identify and enter document information, which can greatly improve the efficiency of both parties. The document information collection system based on computer OCR can be widely used in Internet cafes, public security, banking, telecommunications, postal services, hotels, railways, civil aviation, securities, civil affairs, education, entry...
