Research And Implementation Of Question Card Recognition System Based On Image Recognition

In recent years,the modernization of education in China has been gradually accelerated.In June,2016,the Ministry of Education issued the Notice on the 13 th Five-Year Plan for Educational Information,which paid attention to the work of education information and affirmed the breakthrough progress in the work of "Three Links and Two Platforms".In the cloud computing,large data,mobile computing and other new technologies widely used environment,to promote the modernization of education put forward higher requirements,but also for the education of information technology provides a broader platform.In the policy and market needs,the traditional marking system has been unable to meet the needs of today's schools,it requires optical scanners and dedicated machine-readable card,although the objective problem of marking speed,high accuracy,but its test structure model Fixed,high cost of paper,it is difficult for ordinary schools to answer a large number of questions each test paper and optical scoring machine costs.Therefore,the system set out volumes,generate answer cards,scanning,identification in one,and immediately deal with digital images,according to the structure of the paper identification,and distributed to the teachers in the examination papers in real-time assessment of the examination papers and statistics,and finally after large data Analysis,the test scores for statistical evaluation.This paper mainly focuses on the question-card creation and recognition based on the structure of the test paper.It is mainly based on the image recognition technology to briefly discuss the learning,identify the contour of the answer card using the edge recognition algorithm,then locate the target point,affix transformation to the answer card Bar code area,the objective area,the subjective area,such as accurate identification,so that the bar code automatically identify the candidate information,the objective of the answer output characters,the subjective,the subject of the problem,Title according to the title cut.Based on the image recognition of the answer card recognition system using digital image processing technology to answer the question of identification cards in the ordinary computer can design and implementation of the answer card production and identification,to overcome the optical scoring machine must use special equipment shortcomings.The system can reduce the waste of examination resources,save teachers' marking time and statistical examination results,and the recognition accuracy is high.In this paper,the automatic generation of the answer card template,the corresponding identification card image recognition algorithm widely used,flexible,easy to maintain,has been successfully promoted in many local high school and use,there is a very good evaluation and feedback.
