| 摘 要： | 文章介绍了一个新型的电子电路图纸自动读入系统的构成及其实现。这是一个新进研制成功的实验系统,它不同于以往的常规系统。本文扼要地介绍了其中的模式分离与图象识别技术:对于前者,着重讨论基于Freeman链码边缘跟踪技术的字符分离方法;而对于后者,文中包括二方面的内容;实现字符识别的人工神经网络方法与实现符号识别的决策树方法,最后给出系统的输出结果。

| Abstract: | In this paper we present a new structure of automaticl read-in system for the electronic circuit drawings . It is a prototypy which has been developed by us recently. This system is different from others.We principally describe the methods of the pattern separating and electornic circuit symbol recognition . For the former , we shall discuss the character separating based on the edge-trace technique of Freeman chain-code, for the latter, we shall present a charcter recognition method based on the artificial neural networks and a symbol recognition method of electornis circuit based on the decision tree, finally the output graphy after recognition is given. |
