摘 要
相比传统的纸质阅卷模式,答题卡的出现帮助教师缓解了试卷批阅的压力,答题
卡配合光标阅读机的阅卷模式也逐渐普及应用,然而光标阅读机购买及维护费用较高
不利于普通学校的使用。随着计算机视觉研究的不断发展,答题卡识别也成为了计算
机视觉研究的重要内容之一,随着图像识别技术及人工智能系统的快速推广和应用,
可以利用图像识别技术对答题卡进行图像处理,同时通过信息的识别比对来实现成绩
的计算和存储,借助答题卡识别技术可以实现更加便捷的答题卡得分统计,进一步提
升教学阅卷的效率同时对普通学校及个人也可以实现灵活的应用。

Abstract
Compared with the traditional paper marking mode, the emergence of answer cards
has helped teachers relieve the pressure of examination paper review, and the marking
mode of answer cards with cursor readers has gradually become popular, but the high
purchase and maintenance costs of cursor readers are not conducive to the use of ordinary
schools. With the continuous development of computer vision research, answer card
recognition has also become one of the important contents of computer vision research,
with the rapid promotion and application of image recognition technology and artificial
intelligence system, image recognition technology can be used to image processing the
answer card, and at the same time through the recognition and comparison of information to
achieve the calculation and storage of grades, with the help of answer card recognition
technology can achieve more convenient answer card score statistics, further improve the
efficiency of teaching and marking at the same time for ordinary schools and individuals
can also achieve flexible application.
