Intelligent Marking for Mechanical Drawing Answers
Lin Da-jun · 2011
According to the standard answers of vector figure,geometric information and topological information data is extracted as the evaluation criteria of question,a technique of intelligent marking algorithm for mechanical drawing answers is proposed and implemented based on the standard documents drew by AutoCAD software.By analyzing the model of graphical data classification and storage,standard graphic information is classified and extracted.Then,the corresponding graphic objects under the type of graphic elements are compared and matched respectively,annotation is made and appropriate points is deducted for error answers,therefore,scores can be calculated,and intelligent marking process is realized.
