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.
