摘要
AutoCAD环境下工程图学的作业和试卷的智能化评阅中,文本的自动判别是重要的一部分,为了解决这一问题,文中根据AutoCAD中一般图形识别的原理和文本特有的属性特征,对AutoCAD环境下工程图形中文本判别可能出现的“漏填”、“错填”、“多填”、“位置不对”等情况作了分类讨论和研究,并在AutoCAD内嵌的VBA编程环境中,进行了程序实现,可广泛应用于基于AutoCAD的工程图学的智能化作业或是智能化考试软件中。
Automatic identification of text is an important step to realize computer aided marking of homework and examination for engineering drawing in AutoCAD environment. Investigated thoroughly on how to distinguish characters in AutoCAD according to the principle of identifying engineering drawing and belonging of characters. Studied and categorized various error forms, such as ＂no fill＂, ＂multiple fill＂, ＂wrong fill＂, and so on. Solutions to those errors were also given and programmed using VBA in the AutoCAD environment. This program can be widely used in intelligent software to mark homework and examinations for engineering drawing based on AutoCAD.
