Research on Answer Sheet Identification and Judgment System Based on OpenCV
The answer sheet recognition system in this paper achieves efficient and accurate recognition and judgment of answer sheet through the design of answer sheet templates,image acquisition,image preprocessing,recognition algo-rithms,grading,and other processes.Through testing,the system is verified with high accuracy,efficiency,and real-time performance,with good adaptability and scalability.It can be flexibly expanded and upgraded with increasing demand.Compared to traditional optical scanning systems,the answer sheet recognition and judgment system does not require pro-fessional optical scanning equipment,and only requires a regular USB camera or mobile phone camera to achieve the an-swer sheet identification and determination.This system has the advantages of being more flexible and convenient.
