摘要
为了制止学生使用AutoCAD绘图在各类教学中的诸多图形相似行为,在TRIZ的九屏幕法启发下,提出基于AutoCAD绘图过程的相似辨识方法。利用ObjectARX开发了学生端记录辨识图形相似的特征信息插件,基于Python、Django、MySQL等开发了B/S模式的教师端图形相似辨识系统。先通过九屏幕法对问题进行分析,得到解决问题的资源;其次,分析学生绘图过程的产生相似图形的绘图方式;再次,分析这些绘图方式所引起的特征信息变化;然后,利用开发的插件将特征信息存入数据库;最后,使用这些特征信息来进行相似图档的辨识。通过教学实践表明这套方法可以有效制止学生图形相似,显著提高计算机绘图的教学效果。
In order to prevent students from using AutoCAD to draw many similar behaviors in various teaching,inspired by the nine-screen method of TRIZ,a similarity identification method based on AutoCAD drawing process is proposed.Using ObjectARX,a feature information plug-in for student-side record recognition and graphic similarity was developed.Based on Python,Django,MySQL,etc.,a teacher-side graphic similarity recognition system in B/S mode was developed.Firstly,analyze the problem using the nine screen method to obtain resources for solving the problem;Secondly,analyze the drawing methods used by students to generate similar graphics during the drawing process;Again,analyze the changes in feature information caused by these drawing methods;Then,use the developed plugin to store the feature information in the database;Finally,use these feature information to identify similar image files.The teaching practice shows that this method can effectively prevent students from similar graphics,and significantly improve the teaching effect of computer graphics.
