Integrated Design and Recognition Algorithm of Identification Codes in Examination Paper

设计一种可简单书写的数码数字,并将其作为学号识别码直接集成在试卷上,有效地实现试卷与学生的一一对应关系.分析纸质扫描试卷识别码的识别算法,处理了识别中可能出现的多种异常情况,并将该设计和算法应用到选择类试题答案的自动识别和批阅中.实测结果表明:所提出的集成设计,具有占用空间小、连写简便、识别快速、识别率高和低成本等特点.

It designs a simple and easy-writing digital numbers and takes them as recognition identification codes integrated in the examination paper. This design effectively realizes the one-to-one correspondence be-tween the student and his examination paper. It analyzes the recognition algorithm of the digital numbers in scanned examination paper, and solves several abnormal conditions in the recognition process. The design and recognition algorithm are also applied to the automatic identification and marking of objective questions. The experimental results show that the proposed design and recognition algorithm have the advantages of small oc-cupied space, easy-writing, rapid recognition, high rate of recognition and low cost etc.
