Research on Similarity Recognition Method of Computer Graphics Based on Nine-Screen Method
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 signifi-cantly improve the teaching effect of computer graphics.
