摘要
答题卡识别系统通过答题卡模板设计、答题卡图像采集、图像预处理、识别算法、批阅和评分等环节,实现了对答题卡进行高效、准确的识别和判题。通过测试验证,该系统具有高精度、高效性和实时性,具有较好的适应性和可扩展性,可以随着需求的增加灵活扩展和升级。相较于传统光学扫描判题系统,该答题卡识别判题系统不需要专业的光学扫描设备,仅需要普通的USB摄像头或者手机摄像头即可实现答题卡识别和判题。该系统具有更为灵活和便捷的优势。
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 algorithms,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 professional optical scanning equipment,and only requires a regular USB camera or mobile phone camera to achieve the answer sheet identification and determination.This system has the advantages of being more flexible and convenient.
