智能图元特征提取与图形匹配技术

Graphic Elements’ Characteristic Extracting Technique and Graphic Matching Technique for Intelligence Correction

实现作业的智能化批改是本课程多年来未能突破的技术难点,作者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。并找到了图形匹配的方法,研究了图形匹配技术,并且成功地利用图形匹配技术,实现了规则图元和非规则图元(曲线)的智能批改。

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 finds and studies the graph matching technique. With the help of it, normal and abnormal graphic elements＇ intelligence correction is feasible.
