Design And Implementation Of Integrated Information Collection And Recognition Software System For Identity Card

Identity-card is the valid document that prove the identity of the holder,in the airport,railway station,hotel,mobile phone business hall,bank and other place,are required to use the second generation of identity card for identity authentication.In the process of certification,we need through reading the identity card chip information to complete the identification of identity-card and automatic input personal information.After that,it's necessary to identify the consistency of identity-card and cardholder by human eyes.The current identity card authentication method is not efficient,and loopholes exist when identify the authenticity of identity-card.Besides,there are problems of inconsistencies between Identity-card and it's holder.In the view of above situations,this paper based on the relevant hardware platform,design and develop a software system that integrates ID card image acquisition,chip information reading,identity card authentication and cardholder identification.First of all,we designed ID card image acquisition PC program,receiving ID card image data collected by CIS sensor.Aiming at the dark color of the original image of the collected ID card and the presence of fringe noise,this paper designed a pre-processing method of brightness compensation image correction based on CIS sensor.And through the edge detection and image scaling method to standardize ID card image.Second,this article uses the Ministry of Public Security certified non-contact second-generation card reader secondary development module on the identity card reader to develop the design,read ID card built-in chip information.This paper also realizes the character recognition method based on feature extraction and SVM classifier,and according to the characteristics of ID characters,the design of different classifiers on the identity card on the different character information classification and identification,greatly enhance the ID card character recognition speed.By comparing the identity card chip information and identify the text information,identify the authenticity of identity-card.Finally,this paper location and split out the human face from ID card image,through the camera real-time detected human face head,identify whether the identity-card holder matching the identity card.In this paper,the C ++ language is used to implement the above algorithm,and the related software is developed with MFC.After the experimental test,the system has a high degree of image resolution,chip information read stability,the identity-card image text information has a higher recognition rate,and face detection effect,with face recognition function.
