摘　　要：针对现有试卷分析过程中需要手工录入、统计和分析成绩,导致繁琐费时等问题,提出了基于手写数字识别的试卷分析系统。首先利用图像处理技术增强需处理的试卷成绩表区域;然后使用改进的LeNet-5卷积神经网络识别分数;最后,采用OpenPyXL和Python-Docx库函数完成成绩保存、分析和报告自动生成。实验表明,该系统能提高试卷分析效率,减轻教师工作负担。In view of the tedious and time-consuming problems caused by manual input,statistics and analysis of scores in the process of test paper analysis,a test paper analysis system based on handwritten digit recognition is proposed.First of all,the image processing technology is used to enhance the area where the test paper score sheet needs to be processed.Then the improved LeNet-5 convolution neural network is used to identify the score.Finally,OpenPyXL and Python-Docx library functions are used to save,analyze and report the results automatically.The experimental results show that the system can improve the efficiency of test paper analysis and reduce the burden of teachers.
