【摘要】 研究矢量图形识别是建立工程制图自动阅卷与计算机辅助教学系统的基础。由于组成二维矢量图形图元类型的多样化及图形整体位置状态的不确定性,增加了矢量图形的识别与判断难度。结合开发的《三视图智能解答》系统,研究其智能识别与判断技术。系统中引入三视图导航技术,解决了图形整体定位与识别问题。实现了对矢量图形图元素信息的分类和提取,能够对所提取的的信息与标准答案进行智能判断与评定。该方法已在AutoCAD2000环境下使用AutoLISP语言编程实现。更多还原

【Abstract】 It’s a basic that research and estimate vectorgraph for based a system of read test paper automatically and computer assistant teaching in engineering drawing. Graph cell style is diversification and place of whole graph is incertitude for composing two dimension vectorgraph, then it increase difficulty for research and estimate vectorgraph. As airmanship for three-view drawing is introduced in system, and combine the system is already empoldered that《three-view drawing intelligent solution》to do research for intelligent estimate technology, resolve the problem that is orientated and distinguished for whole graph.Realized sort and pick-up for basic information of element for vectorgraph, can do intelligent estimate and assess for pick-up information and normal solution. This method was run in AutoCAD2000 by AutoLISP program.更多还原
