SBIR Phase I: An Expert System for Automated Digitizing of Engineering Drawings

在已安装的计算机辅助设计（CAD）系统中， 将现有的纸质图纸转换为等效图纸的问题 在CAD系统中以电子方式存储表格已被证明是困难的 来解决 如果有计算机辅助设计系统， 一种自动的方法来转换许多现有的图纸， 电子表格，其中原始图纸上的信息 而不是迷失 研究正在进行中，以创建一个系统， 然后，将绘图解释存储在 图纸 将建立一个计算机化的专家系统来执行这一任务 任务 对于每个应用领域，专家系统将使用规则和 在特定领域的图纸知识来翻译数据 变成一种可用的形式。 将制定Vexcel战略， 以可接受的误差产生可接受的吞吐率 这是任何商业系统的基本要求。

In computer-aided design (CAD) systems that have been installed, the problem of converting existing paper drawings into an equivalent electronically-stored form within the CAD system has proven difficult to resolve. CAD systems would be much more effective if there existed an automatic method to convert the many existing drawings into electronic forms, in which the information on the original drawings was not lost. Research is in progress to create a system that would digitize a drawing then interpret the information stored on the drawing. A computerized expert system will be created to perform this task. For each application field, the expert system will use rules and knowledge about drawings in that particular field to translate the data into a usable form. Vexcel strategies will be developed that will result in an acceptable throughput rate at an acceptable error rate--both essential requirements for any commercial system.
