高校中的计算机绘图考试近几年的考试方式基本上以上机为主,来考察学生的作图能力.结合多年的教学实践,针对评卷方式向计算机智能评判方式转化的发展趋势,采用图像处理技术,实现对图像关键信息的提取,基于图像相似度的计算原则编制图像相似度程序,对学生的作答图与标准图形进行对比,进而实现 CAD 图形自动阅卷判分功能.通过实例计算,得到的判卷成绩与人工阅卷成绩理想化的一致,判分速度快,提高了教师的工作效率.

The examination of the Computer Graphics is basically the computer examination to investigate the drawing ability in universities in recent years. Based on many years of teaching practice and according to the transformation trend of the computer intelligent paper marking, the image processing technology is adopted, and the key information of the image is extracted, and the image similarity calculation program is compiled, and the CAD automatic papermarking fuction is implemented by the contrast of the students'plot with the standard answer. Through the calculation examples, the grading results is consistent with the artificial results ideally. The calculation speed is faster than the manual speed, thus the teacher's working efficiency is improved.
