【摘要】 实现作业的智能化批改是计算机工程制图课程多年来未能突破的技术难点,该文要解决的正是这难点。其关键技术是图元特征提取与图形匹配,它为智能化批改的算法、设计与实现做了理论上的准备。该文详细介绍了各种图元智能批改算法,并且利用了DC[1]方法,实现了规则图元和非规则图元(曲线)的智能批改。更多还原

【Abstract】 Homework intelligence correction was a longtime obstacle for computer engineering graphics.The paper presents the solution.Its critical point is graphic elements’ characteristic extracting and graph matching,which is also served for the design of intelligence correction algorithm in theory.It introduces all kinds of graphic element intelligence correction algorithm,and take use of DC,which realizes regular graphic elements and irregular graphic elements intelligence correction.更多还原
